However, the population increase is still hindering that development. One of the major apparent effects for the impediment is the low rate of protein per year for each person specially fish protein when compared with the global average. Fishing has existed since the dawn of mankind. Actually, it is considered one of the oldest ways for obtaining food. Being that old has permitted for the invention and development of fishing vessels. Not only they developed into various types but also, they developed into different sizes Stern trawlers are one type of fishing vessels. They can contribute with an enormous part in providing fish to local markets. This fish is preserved using ice but it does not remain as fish as when it is recently caught. Some stern trawlers are fitted with a processing factory (Factory stern trawlers). When so they become a driving for economy by providing various fish products not just fish. Fish processing increases the value of the products, enriches the markets with this variety, and can be a stable source of foreign currency upon exporting any excess. All these reasons encouraged us to pursue this project in which we aim to achieve an applicable design of a factory stern trawler that may one day assist in pushing the Egyptian economy forward. iii

Dept. INTRODUCTION Fishing economy As long as man existed, he has engaged in the profession of fishing, which makes this activity as old as human existence in the world. Fishing is a global industry. During last 10 years only, the gross global revenues from fisheries only have reached nearly $85 billion annually according to the FAO. [ Fish products have an essential role to play Egypt as well. The Egyptian fisheries resources in marine and fresh waters contribute to people's welfare in the form of nutrition, income, business and foreign currency source from exports. Figure 1: Ancient Egyptians catching fish Fisheries in Egypt Egypt has been fortunate to be located in a position that overlooks to two major seas several lakes and a river providing 11.2 million acres of fisheries. These fisheries are located in: Mediterranean Sea The arable area for fishing in the Mediterranean is nearly 6.8 million acres including areas of 1. 2. 3. 4. 5. Max and Abu Qir in Alexandria Matrouh Rashid, El-Maadia and Baltim in Kafr El-Sheikh Port Said and Izbet El-Borg in Damietta El-Arish in North Sinai 2 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Red Sea The arable area for fishing in the Red Sea is 4.4 million acres, including areas of 1. 2. 3. El-Tor and Dahab in South Sinai Hurghada in Red Sea Governorate Gulf of Suez in Suez Governorate. Nile River, Lake Nasser and Others Figure 2: Aquaculture regions in Egypt 3 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Fisheries production in Egypt [ Despite this large area of fisheries, Egypt’s production of fish does not exceed one 1.34 million tons annually. When compared with the global average, Egypt’s production is considered very low. The global average ranges between 80 and 100 kg of fish protein per year for a person while in Egypt, it is staggering at a rate of just 12 kg per year and that number is falling drastically.

Dept. Causes of fisheries poverty in Egypt There are many reasons behind fisheries poverty in Egypt. They include: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Throwing sewage of touristic villages in the sea along the coasts of Red Sea and the Mediterranean. Throwing sewage of ships at sea. Lack of control over ships. Lack of control over fishermen. Lack of control over the machines and fishing equipment. Ignorance of fishermen and lack of awareness. Fishing spawning seasons. Overfishing. Violation of rules of the net opening sizes (leads to catching small fish and destruction of fisheries eventually). Weakness of the Mediterranean fertility (half of that of the ocean). Figure 3: Dumping at sea 5 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Preservation of fisheries in Egypt According to analysts, the seafood, including fish, will run out by 2050. The whole world as well as Egypt has a vital role in helping to prevent that from happening. This can only be achieved by: 1. 2. 3. 4. 5. 6. 7. Better control over ships. Better control over fishermen. Better control over the machines and fishing equipment. Banning fishing in spawning seasons. Banning dumping of sewage of the ships at sea. Banning dumping of sewage of touristic villages at sea. Increasing the awareness. 6 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. CH.2: FISHING VESSELS 7 Design of a Factory Stern Trawler Fishing vessels Naval Arch. and Marine Eng. Dept. Fishing vessels Fishing vessels are specialized vessels to catch and haul fish from inland waters, high seas or even oceans. They are indispensable to maritime operations because they help to answer the supply demand of fish and fisheries sector. Although their role is uncomplicated, their absence would create a problem. At present, fishing is done by using diverse types of fishing vessels. Types of fishing vessels Purse seiners Purse Seiners are used mainly in the oceans; their utilization of seine fishing nets is the main reason of the name. Their fishing nets shape is exceptional. They are used to catch the fish near the surface. During deployment the nets feature a floating apparatus, but once the fish enter it, the lower part shuts to trap them. Figure 4: Purse seiner These fishing boats are aided with the most advanced technological appliances to enable high fish revenues. 8 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Trawlers Trawlers are one of the most used fishing vessels. These vessels have trawler nets that are suspended by assisting equipment and trailed under the surface of the water, hence the name. Deepness is required to haul and trap the fishes. Trawler vessels are employed to catch a wide array of fishes and for almost every country in the world. Figure 5: Stern trawler Longliners Longliners are different from all other fishing vessels. They use just one really long fishing cord containing up to 1,000 lures instead of fishing nets. The fishing cord is deployed from the stern of the vessel. The vessel maintains its position using automated system that also help reel the haul onboard to be stored Gillnetters Gillnetters are specialized boats that use vertical panels of netting normally set in a straight line known as gillnet system. This system can be either: 1. 2. 3. Set gillnets Encircling gillnets Combined gillnets-trammel nets 9 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Figure 6: Longline Figure 7: Gillnetter Crabbers Crabbers are fishing boats that are specialized to fish for crabs. They are equipped with special equipment to catch crustaceans. Automated windlasses are equipped to haul the trappings. Figure 8: Crab trapping 10 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Drifters Drifters refer to those fishing boats whose nets hang vertically in the water without being anchored. Drift fishing nets haul and trap the fishes. The net is thrown into the water forming a curtain to catch the fish. Figure 9: Drifter Factory ship Factory ship is a ship that does not only catch fish but also it freezes and processes the haul. It is used in deep seas and oceans. The idea of this type of ships originated from the fact that the lifetime of the catch is limited. In order to increase that lifetime, the fishing vessel is equipped with the appropriate facilities for processing and preserving the fish. Factory ships can operate up to six or seven weeks in one journey. They also can function as mother ships that store and process the haul brought by smaller fishing vessels.

Figure 11: Fish processing facilities on board a factory ship 12 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Types of fishing vessels in Egypt From all these types of fishing vessels, only certain types are commonly used in Egypt. These types have characteristics that vary from the general characteristics.

DESIGN METHODOLOGY Hull Surface Generation For generating the vessel’s hull, there are two possible ways: 1- Generating an offset table from a series. 2- Scaling a built-in model from a ship design package (Maxsurf). The available series has not shown a satisfactory suitability for the given requirements. On the other hand, a Maxsurf stern trawler model that is scaled is considered a far better option in this case.

CH.4: GENERAL ARRANGEMENT FOR TUNA BAIT 22 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. GENERAL ARRANGEMENT Deck arrangement The superstructure is placed forward with the working deck aft. Gallows are placed on the stern quarters or there is a stern gantry for the operation of the other boards. Net drums and winches are installed to assist in the handling of gear and catch. Fish pumps are often installed on pelagic trawlers. In most cases the handling of the catch and any processing of fish take place below deck or in deck houses. Consideration which should be taken during deck layout selection 1. Trawl warps lead in at right angles to the trawl winch. 2. No possibility of snagging shackles as no interference between ropes on the different load. 3. Minimum number of sharp bends at warps. 4. Large area should be available for fish processing. General design considerations Stern trawlers with fish holds aft and accommodation above main deck Advantages 1. Accommodation could be located above the main deck to reduce the ship length. 2. Fuel oil tanks are located aft to maintain the ship at even keel in the right condition. Disadvantages 1. Torsion stresses in the propeller shaft increase as the shaft length is increased. 2. Locating fuel oil aft increases the piping system length. Stern trawlers with engine room aft and accommodation above main deck Advantages 1. Torsion stresses in the propeller shaft decreases as the shaft length is reduced. 2. There is no need to raise inner bottom under the fish hold to accommodate the propeller shaft which in turn decreases the scantling of the solid floor and increases the capacity of the fish hold. 23 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Disadvantages The fish hold is centered forward of amidship so that the vessel may change trim undesirably between loaded and unloaded conditions. Stern trawlers with engine room aft and accommodation below main deck Advantages 1. The fish hold is located amidship (at the maximum fullness to accommodate maximum capacity). 2. This arrangement is recommended for small crew numbers (3 to 4 people). 3. No change in trim due to loading and unloading. Disadvantages Loading accommodation forward reduces the fish hold capacity. Crew accommodation Crew accommodation arrangement varies with climate and local customs, but in all cases the crew requires sleeping and eating spaces. These spaces must be provided with adequate ventilation and means of protection from the weather. Protection from excessive noise is also a necessity and must meet the local standards and regulations of safety and health. Sleeping rooms The floor area per person excluding spaces occupied by berths and lockers should not be less than 0.9 m2. Mess room 1. Should be separate from sleeping quarters. 2. Should be as close as possible from the galley. 3. Furniture and equipment should be sufficient for the number of people existing in the mess room at any time. 24 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Sanitary room Should include 1. One shower bat for every eight people. 2. One water closet for every eight people. 3. One wash basin for every six people. Galley Minimum outfitting it includes 1. A kerosene or bottled gas burner. 2. Bench and sink for dish washing. 3. Table for good preparation. Navigation The wheelhouse should be laid out with exceptional care as it is the key element of any vessel and in a constant use as long as the ship is at sea. The wheelhouse should have 1. Conveniently arranged steering position with a wheel of adequate size. 2. Navigation area where chart can be laid out on a conventional surface with chart and navigating instruments. 3. Space for the location and operation of any electronics instrumentation to be carried. 4. Adequate floor spaces for helmsman and other operation personnel in the wheelhouse. Equipment Equipment on board fishing vessels can be classified into four main categories: 1234- Nautical equipment Fishing Equipment Communication equipment Deck equipment 25 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Nautical equipment Sonar Sonar is an abbreviation for SOund, NAvigation, and Ranging. Sonar is an abbreviation for SOund, NAvigation, and Ranging. Sonar is used for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves. It is also used for developing nautical charts, locating underwater hazards for navigation, searching for and mapping objects on the seafloor such as shipwrecks, and map the seafloor itself. Sonar has two types. Figure 16: Radar scans a) Active Sonar Active sonar transducers give off a sound pulse into the water. If the sound pulse is obstructed by anything in its path, the sound bounces off the object and returns to the sonar transducer as an echo. The transducer can be also used to measure the strength of the signal on the occasion that the transducer is equipped with appropriate equipment. The range and orientation of the object is determined by measuring the time interval between the emission of the sound pulse and its reception. b) Passive Sonar Marine animals such as whales and marine objects such as submarines are prone to produce noise. Passive sonar systems are developed to detect these noises without emitting a source signal. They offer an advantage for the military purpose that is stealth, or for scientific missions that concentrate on quietly listening to the ocean do not want to disturb their equipment with unwanted noises. 26 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. One of the disadvantages of this system is that it can’t measure the range of the object without being linked to other listening devices. Multiple passive sonar devices may allow for triangulation of a sound source. Figure 17: Active Sonar Figure 18: Passive Sonar 27 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Echo sounder Echo sounder is a special type of sonar. It is used to calculate the water depth by transmitting sound pulses into water. The time interval between emission and return of a pulse is recorded, and then used to determine the depth of water along with the speed of sound in water at the time. This information is used either for navigational purposes or in order to obtain depths for charting purposes. Another use for echo sounding is studying the marine life. In this case it is referred to as hydroacoustic echo sounders. Figure 19: Fish aggregations recorded by echo sounder Gyrocompass Gyrocompass is a non-magnetic compass. It is a fast spinning disc that depends on the rotation of the Earth. It is used to find the geographical direction. One of the main components of the gyrocompass is the gyroscope. However, there are different devices. The gyrocompass only exploits the effect of gyroscopic precession. Gyrocompasses are widely preferred to magnetic compasses in ship navigation because of two main reasons: • They find the true north which is defined by the axis of Earth’s rotation which is different from magnetic north and more useful navigationally. 28 Design of a Factory Stern Trawler • Naval Arch. and Marine Eng. Dept. They are not affected by ferromagnetic materials which distort the magnetic field such as the ship’s steel hull. Figure 20: Gyrocompass in the bridge Marine radar Marine radars are one of the most important equipment onboard ships. They are used to detect other ships and land obstacles, to avoid for collision and for navigation at sea. They can be X band or S band. They use a rotating antenna span a narrow beam of microwaves around the water surface surrounding the ship. When these microwaves are reflected from the targets back to the radar, they are detected. The radar displays a picture of the ship’s surroundings on a display screen. Radar is a vital component of safety. In the worst-case scenario at sea or near the shore, where there is no visibility at night or due to bad weather, the ship’s captain should be able to steer and maneuver the ship blindly using the radar. In commercial application, radars are not used alone. They are integrated within a complete system of instruments that can be complex and distracting to look at several different screens. Because of that that integration must be handled carefully, and displays overlay charting, radar, sonar into a single system. 29 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Figure 21: radar scan Chartplotter Chartplotter is a device used in marine navigation that integrates GPS data with an electronic navigational chart (ENC). The chartplotter displays the ENC along with the position, heading and speed of the ship, and may display additional information from radar, automatic information systems (AIS) or other sensors. Aside from positioning, these types of navigation tools will also notify you once your vessel is within close proximity to hazards such as reefs, rocks, shoreline, and other obstructions under the water. Figure 22: Chartplotter A marine GPS chartplotter is commonly placed on the controls of the marine vessel; and if it has an external GPS antenna, this antenna is usually placed on top of the ship. The process of providing the navigation information starts with GPS getting signals from multiple satellites. These signals are then converted by the chartplotter into longitude as well as latitude data. This data is then shown on the chartplotter screen. The information that is shown includes water depth, obstructions on the path, environment, and other small but important data. 30 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Speed Log Speed log is a ship speed measuring device. There are many types of speed logs. 1. 2. 3. 4. 5. Electromagnetic log. Doppler log. Impeller log. Pito meter log. Acoustic Co-relation Log. Electromagnetic log The electromagnetic log works by generating a small alternating current in a transducer producing an electromagnetic field in the adjacent water. As the vessel moves through the water, the voltage proportional to the speed is generated at 90⁰ to the direction of travel. This signal voltage is detected by the probes and transmitted to the master electronic unit where it is amplified and processed digitally before being passed to the speed and distance displays. Doppler log Doppler log is an acoustic speed log based on the Doppler Effect in which the wave lengths of moving objects appear to shift in relation to the observer. This shift can be converted to speed, thereby giving a very accurate result. The Dual Axis Doppler Speed Log utilizes the Doppler shifted returns from high frequency acoustic energy transmitted into water to provide precise speed data, distance travelled, and water depth below the transducer. The transmitted signal is scattered back from the sea bottom and/or scatters in the water mass. The system amplifies the received signals and processes them to determine the Doppler shift. The time required for the signal to bounce back from the sea bottom is measured to calculate depth. The standard system consists of a Master Display Unit, an Electronics Unit, a Transducer Assembly, a Sea Chest or Tank, and interconnecting cabling. Autopilot An autopilot (or pilot) is a mechanical, electrical or hydraulic system which can maintain a vessel on a predetermined (set) course without the need for human intervention. Using a direct or indirect connection with a vessel’s steering mechanism, the autopilot relieves the crew from the task of manually steering the ship. Figure 23: Ship autopilot Autopilot have evolved from simple course holding systems to adaptive computer systems that offer reduced fuel costs and increased transit times. These new systems learn the characteristics 31 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. of the vessel’s handling and minimize rudder movement reducing drag on the vessel. Increased speed and lower fuel consumption makes autopilot more user friendly. Autopilots do not replace a human operator, but assist them in controlling the ship, allowing them to focus on broader aspects of operation, such as monitoring the trajectory, weather and systems. Communication equipment AIS (Automatic Identification System) AIS is a maritime technical standard developed by the International Maritime Organization (IMO). AIS is a sophisticated radio technology which combines GPS, VHF and data processing technologies to enable the exchange of relevant information in a strictly defined format between different marine entities. This may be the simple exchange of position, course, speed and identity information between individual vessels or more sophisticated data exchanges between specialist shore and buoy located devices. Types of automatic identification systems are: Class A They report their position autonomously every 2-10 seconds dependent on the vessel’s speed and/or course changes (every three minutes or less when at anchor or moored); and, the vessel’s static and voyage related information (message 5) every 6 minutes Class B They report every three minutes or less when at anchor or moored, but, their position is reported less often and at a lower power. Likewise, they report the vessel’s static data every 6 minutes, but, not any voyage related information. Search and Rescue Aircraft It is aircraft mobile equipment that is normally reporting every ten seconds. AIS Aid to Navigation (ATON) It is a shore-based or mobile station providing location and status of an aid to navigation (ATON); which may also broadcast Application Specific Messages. AIS Search and Rescue Transmitter (SART) It is mobile equipment to assist homing to itself (i.e. life boats, life raft). When active the unit also transmits a position message (message 1 with a 'Navigation Status' = 14) in a burst of 8 messages once per minute. 32 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. AIS Base Station It is a shore-based station providing identity, time synchronization, text messages, which can also act as an AIS ATON station or transmit Application Specific Messages for meteorological or hydrological information, marine safety information, etc. Figure 24: Automatic Identification System (AIS) configuration VDR/S-VDR Information is stored in a secure and retrievable form, relating to the position, movement, physical status, command and control of a ship over the period and following an incident. This information is used during any subsequent safety investigation to identify the cause of the incident. VDR or voyage data recorder is an instrument safely installed on a ship to continuously record vital information related to the operation of a vessel. It contains a voice recording system for a period of at least last 12 hours (for Figure 25: VDR VDRs installed post-July 2014, the period of the integrated details recorded is 48 hours as per the MSC Resolution 333.90). This recording is recovered and made use of for investigation in events of accidents in a compressed and digitized format. 33 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. A ship’s VDR is far superior to a black box of an airplane as it stores a variety of data and that too for not less than a period of 12 hours. The data records covering the last 12 hours are continuously overwritten by the latest data. The S-VDR is nothing but a simplified VDR. It records information that is only absolutely necessary and does not record information as extensive as the VDR. Naturally, it is more cost effective and more in usage on board ships. A VDR is capable of withstanding heavy weather, collisions, fires and pressure conditions even when a ship is at a depth of several meters in water. The VDR can be classified to Data Collection Unit (DCU) It is fitted on the bridge that pulls in data from all the integrated sources. Data Recording Unit (DRU) It is fitted on the monkey island that stores all of the data that is recorded via the unit within the wheelhouse) and microphones to record bridge audio. The flash memory in the DRU stores the data coming from the DCU. The data can be retrieved by using playback software for investigation after an incident. The DRU components are embodied in the protective capsule. The capsule ensures survival and recovery of the recorded data after an incident. Inmarsat (International Maritime Satellite) Inmarsat is perhaps the most reliable communications method in the marine industry; however, it is shadowed in the Polar Regions by the curvature of the earth. There are several technologies employed in this system and they are identified as Inmarsat A, Inmarsat B, Inmarsat C, Inmarsat M4 and Fleet 77. VSAT VSAT is an acronym for Very Small Aperture Terminal. VSAT is a continuous connection satellite system that requires a shore-based hub system. They provide high bandwidth, broadband Internet connectivity for vessels. VSAT is an extremely reliable but often expensive system to operate. Typically, they are used where high data rates are required. 34 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Figure 26: VSAT configuration Figure 27: VSAT coverage 35 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Fishing Equipment Trawl winches Trawl winches are electrical winches aboard fishing vessel used to drag the net during fishing process then hoist the haul onto the vessel. Figure 28: Trawl winches aboard fishing vessels Fish finder Fish finder has the same concept as Sonar. It is used primarily to locate fish, underwater. A fish finder displays the location of a fish in a digital screen that can be either of a LCD or a CRT type. The technology of the fish finder was first used in the 90s and has been constantly upgraded since. Modern electronics allows a high degree of integration between the fish finder system, marine radar, compass and GPS navigation systems. One of the parts of the main components of a fish finder is the transducer. It is the sensor portion of the Fish finder. There are 2 types of transducers used in Fish finder: • • Single frequency Dual frequency. Single frequency is generally best for lakes and shallow coastal fishing. Dual frequency transducers are generally better for deep sea fishing. Dual beam and dual frequency are essentially the same thing. Dual beam transducers limit the beam size for the high frequency beam so these depth finders are truly best for deep water. Figure 29: Fishfinder Higher powered Fish finder are expensive, yet they are better. Even in shallow water such as lakes, higher power will still help with better imaging. The most weight to the power rating is often recommended for a unit. 36 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Net drum Net drum is a wide powered spool (usually hydraulic) on which a trawl net is wound when hauling. It can be used alone or aided with other equipment to haul the trawl net aboard. Net drums are offered in a variety of pulls and net capacities. There is a choice of low pressure hydraulic or frequency controlled electric drive systems. Figure 30: Fishing vessel net drum Net sounder third wire winches A winch specifically designed for handling cable instead of wire rope. It is typically used to deploy the cable transmitting information from the net sounder which collects data about fish entering the trawl net to the display on the bridge.

Deck equipment Cranes A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places. The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Capstans and Windlasses A ship’s capstan is a drum shaped device that is used for hoisting weights or for winding ship’s anchor cable. In the modern ships, the traditional capstans are replaced by hydraulically or pneumatically operated windlass. A windlass is a complex device meant for the same purpose as that of capstan, but comprised of different parts, which together make the anchorage process smoother and easier. Figure 32: Traditional capstan A capstan differs from a windlass only in the matter of the axis on which the rope or cable is wound (for a capstan it’s vertical axis, whereas for a windlass it’s horizontal) Figure 33: Capstan 38 Design of a Factory Stern Trawler Naval Arch. and Marine Eng.

Dept. CH.8: PIPING SYSTEM FOR TUNA BAIT 191 Design of a Factory Stern Trawler Bilge system Naval Arch. and Marine Eng. Dept. PIPING SYSTEM The bilge system is used to remove small quantities of fluid that have leaked or condensed into a dry space. The system serves the machinery spaces, cargo holds, cofferdams, voids, stores, tunnels and pump rooms. Each space has its own piping but the pump is likely to be shared. The capacity of a bilge system is defined by the diameter of the bilge main and pump capacity for the volume of the enclosed space. The pumping system on the ship must be able to drain water from any dry space when one or more of the ship’s other compartments are flooded. However, the system is not required to empty the flooded space. A flooded passenger ship is required to have at least one bilge pump, with its own power supply, available for pumping. Bilge suctions must have remotely operated suction valves. The minimum number of pumps required is three or more, depending on the ship’s design. Mud boxes and strum boxes (line filters) are fitted at the ends and in bilge lines to stop debris being drawn into the pipe. The requirements for bilge systems on ships carrying dangerous goods are basically the same as those for general cargo ships. However, systems drawing fluids from gas-dangerous spaces are kept segregated with their own pumps and pipes, where appropriate, from systems serving gassafe spaces. Ballast system Ballast is taken on to increase a ship’s draught, particularly the stern draught, when sailing without cargo. On a dry cargo or passenger ship, the ballast system is commonly operated from the engine room. On a tanker, the entire ballast system is commonly located in the cargo area and is operated from a pump room and cargo control room. Ballast piping is usually made from ordinary mild steel which corrodes. Some ships have ballast piping manufactured from glass reinforced epoxy (GRE) which does not corrode, but care is needed with clamping arrangements to ensure that the pipe is secure and does not move along its axis; this may cause coupling joints to fail. Spare sections of GRE piping should be carried, along with joining couplings and gaskets. A ship’s size determines the capacity of its ballast system. 192 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Firefighting systems Piping is used extensively throughout a ship for fire control purposes. The specific features of ships’ firefighting equipment are governed by the International Convention for the Safety of Life at Sea (SOLAS). Many SOLAS requirements have been incorporated into classification society rules. They include: 1. Fire main Mild steel piping fitted with hydrants for hoses where saltwater is used for manual firefighting. The fire main is designed for a typical working pressure of 10 bar. Pipes in the fire main are affected by corrosion both externally and internally. Pipes are joined with flanged connections. 2. Sprinkler systems Small-bore pipes kept permanently charged with freshwater at 10 bar pressure. A sprinkler system is arranged to release automatically at temperatures of about 70°C, so the system can react and extinguish a fire. The system uses saltwater after the freshwater. After use, it must be flushed with freshwater to minimize corrosion. Some systems operate at higher pressures and produce a fine high pressure mist or fog. These systems are used in oil purifier compartments and above diesel engines to protect the high fire risk areas in engine rooms. It has been proven that rapid operation of this system can quickly contain and extinguish pressure-fed oil fires. 3. Water spray systems Usually small-bore piping, which is dry when not in use. A water spray system is operated manually and looks similar to a sprinkler system. 4. Inert gas system Fitted on all tankers over 20,000 dwt and on all tankers with crude oil washing systems. Inert gas piping is usually large diameter low-pressure mild steel, with smaller diameter branch lines. The internal surface of inert gas piping does not usually corrode. The external 193 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. surface is often painted but will corrode if the paint coating deteriorates. The water wash pipework of an inert gas system is usually lined with a corrosion resistant coating, as the wash water from the inert gas scrubbing tower is highly corrosive. 5. Deck water spray systems Fitted on gas tankers, these are prone to rapid corrosion, particularly if not flushed through with freshwater and drained. 6. CO2 piping Relatively small-bore hot-dipped galvanized mild steel piping designed to withstand the surge pressures and low temperatures that occur with the release of CO2. Main CO2 lines are designed to withstand the same pressure as that of CO2 bottles, while distribution lines off the main valve are designed for a lower pressure. Typically, the main line is pressure tested to 200 bar, the design pressure being at least 160 bar. Care must be taken to ensure that the system is fully reinstated after it has been tested. Incidents have occurred where CO2 has not been correctly released as a result of maintenance valves being left in the incorrect position and even worse, the crew not understanding the method of activating the CO2 release system. CO2 release instructions must be clear, concise and available at the release station. Only appointed persons should be permitted to release the CO2. Arrange regular onboard training and instruction exercises. After maintenance has been carried out on the system by either crew or shore technicians, ensure that the system has been fully reinstated and is ready for use. 7. High-expansion foam Uses foam with an expansion ratio of 900 to 1 in mild steel low-pressure piping. Pressure in the lines ranges from 4 to 5 bar. Foam compound in storage tanks is pumped to a foam generator. The system is required to deliver foam at a rate of one meter of compartment depth per minute. 8. Low expansion foam Uses foam with an expansion ratio of 12 to 1 in mild steel low-pressure piping. Typical pressure in low expansion foam piping is 12 bar. 194 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. 9. Dry powder Used mainly for the fixed fire-extinguishing system on the deck of gas carriers and on older chemical tankers. Dry powder is held in tanks and is propelled by nitrogen gas stored in pressure bottles. Dry powder delivery pipes are pressurized to approximately 18 bar. Pipes Carrying Fuel Oil There are two principal types of pipes that carry fuel and they are categorized by the pressure the pipe is designed to withstand. Low-pressure pipes are primarily used to move fuel from a storage tank to a service tank and via feed pump on to injection pumps. High-pressure pipes are used to deliver fuel from an injection pump to an engine combustion chamber. Ship’s fuel is usually stored in double-bottom tanks, deep tanks, side bunker tanks, settling tanks or service tanks. Piping between a service tank and a fuel transfer or booster pump is rated as low pressure. However, between each pumping stage, pressure increases. It is a mistake to assume that even if a pipe’s pressure is relatively low, fuel will not spray from a crack or small hole. A small pin hole in a fuel pipe can atomize leaking fuel even at low pressure, creating a highly volatile mixture of air and fuel. Low pressure fuel pipes, particularly on diesel engines, should be regularly checked for signs of leakage in way of connections and fretting against other piping or objects. Pipe clamp security should be checked closely. Pipes from fuel tanks can pass through ballast tanks, and pipes serving ballast tanks can pass through fuel tanks. Because of pollution risks, classification societies have stringent rules restricting the length of any oil pipe passing through a ballast tank; it must be short, have increased wall thickness and stronger flanges and subjected to more frequent inspections and testing during survey. SOLAS includes requirements for fire safety in engine rooms. In particular, special double-skinned pipes must be used to deliver fuel to engine combustion chambers. These are made of low carbon steel alloys and operate at high pressures between 150 and 900 bar. Double skins are necessary because pipe fracture will cause fuel to spray in a fine aerosol. Fuel will ignite on contact with a hot surface, such as a turbocharger casing or exhaust pipe. The second skin is to guard against direct spraying. The pipe is designed so that fuel will be contained in the annular space between the outer skin and the main pipe, and will drain into a collecting tank fitted with a high-level fuel leakage alarm. 195 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Low-pressure lubricating and fuel oil pipes passing close to a hot surface must be secured against the possibility of oil spraying from a flange. To prevent this danger, the flange is usually taped. In addition, and whenever possible, the pipes are routed clear of hot surfaces. Similarly, to prevent leaking oil falling onto a hot surface, such pipes should never be allowed to run above a hot surface. Fuel oil transfer pipes are usually of mild steel and may corrode. The calculation for minimum wall thickness includes a small allowance for corrosion. As a pipe ages and corrodes, leakage can occur. Inspection programs should concentrate on identifying worn or corroded pipes. Engine cooling systems Water carried in pipes is used to cool machinery. The main engine is cooled by two separate but linked systems: an open system in which water is taken from and returned to the sea (sea-to-sea) seawater cooling, and a closed system where freshwater is circulated around an engine casing (freshwater cooling). Freshwater is used to cool machinery directly, whereas seawater is used to cool fresh water passing through a heat exchanger. Many engine room systems also use sea water to cool oil, condense steam and even produce drinking water. The particular feature of any engine room cooling system is continuous fluid flow. Fluid in motion causes abrasive corrosion and erosion. To reduce the effects of turbulent flows, seawater systems incorporate large diameter mild steel pipes, the ends of which open to the sea through sea chests where gate valves are fitted. If a seawater cooling pipe bursts, both suction and discharge valves will have to be closed to prevent engine room flooding. In order to make sure the valves operate correctly when needed, open and close them at regular, say monthly, intervals. Ensure that all engine room personnel are familiar with the location and isolation of the main sea inlet valves and overboards. Freshwater cooling pipes are generally made of mild steel. These systems are treated with anticorrosive chemicals and should be tested regularly using the chemical manufacturer’s supplied kits to ensure that the water treatment is always at its most effective. Some freshwater cooling systems may become contaminated with microbes and will require treating with biocide additives which are available from the chemical manufacturers. 196 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Hydraulic piping systems Hydraulic pipes are high-pressure pipes. These are used for: 1. 2. 3. 4. 5. 6. 7. 8. maneuvering the steering gear actuating controllable pitch propellers and thrusters control of watertight doors and valves lifting appliances and deck equipment opening stern, bow or side doors moving mobile ramps for hatch covers driving cargo and ballast pumps minor shipboard utilities It is a requirement that hydraulic systems for steering, pitch control and watertight doors have dedicated piping and pumps. Hydraulic pipes operate at very high pressure. Pipes are weakened because of damage, chafe and fretting, or corrosion. They can burst, allowing hydraulic fluid to spray in a highly flammable, atomized oil mist. As a result, hydraulic equipment and pipework must be kept clear of hot surfaces. Alternatively, hot surfaces must be protected by spray shields. It is important to prevent external corrosion of hydraulic piping located on deck. A high standard of cleanliness is necessary when working with, or replacing, hydraulic piping. Check the systems regularly for leaks, corrosion or mechanical damage. If a leakage occurs during equipment operation, ensure personnel stay well clear. High pressure oil can penetrate the skin and lead to blood poisoning. Always ensure that pollution prevention procedures are followed. Steam piping systems Steam is used for indirectly heating oils, water and air. It is also used as a scavenge fire-fighting medium on some slow speed engines. The steel piping that carries the steam must be of seamless construction and joined by flanges with suitable steam-resistant gasket materials. Any welding that is carried out on a steam pipe must be done by a certified welder. Ship’s staff should never carry out any welding on a steam pipe. Temporary repairs may be undertaken, but only after a risk assessment and permission from the owner has been obtained. Emergency temporary repair may include a welded patch or a bolted on clamp with steam gasket material providing the seal, but extreme care should be taken around the repair and the area roped off to prevent personnel access. The pipe must be renewed at the next port of call. Tapered plugs should never be used to plug a leak in a steam pipe. 197 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Every steam pipe and every connecting fitting through which steam passes must be designed, constructed and installed to withstand the maximum working stresses to which it may be subjected. Means shall be provided for draining every steam pipe in which dangerous water hammer action might otherwise occur. If a steam pipe or fitting can receive steam from any source at a higher pressure than that for which it is designed, a suitable reducing valve, relief valve and pressure gauge must be fitted. There have been many accidents resulting in serious injury or death from working on or near steam pipework. Always ensure that the steam line is completely vented with double valve isolation or blank flange before opening a pipe. Always wear the appropriate personal protective equipment (PPE) when opening the pipe, as even when vented, scalding water may still be present in the line. Always carry out a risk assessment and ensure a permit to work is issued. Valve isolation and venting must be cross-checked by another senior engineer. 198 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept.

CH.9: PROCESSING FACTORY FOR TUNA BAIT 204 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. PROCESSING FACTORY Introduction In spite the processing process starts and depends on the previous fishing process, only the indoor activities will be explained for the sake of simplicity. The flow diagram of the fish processing is depicted. Initially, the captured fish on deck is introduced into the processing plant by means of a ramp connected to a hopper which feeds a distribution conveyor belt. A manual classification sends the fish to the filleting line - Product “Fillet”. If it is too big or too small to go to this filleting line, it goes to the whole fish line - Product “HG product”. If it is not able to be processed in time or it does not fit the requirements, it is returned to the sea – Discards. Figure 68: Flow Diagram of the Factory Ship Process 205 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. Processing Steps On the whole fish line, the fish undergo three sequential operations, named heading, gutting and wrapping. Heading and gutting operations are performed by two machines assisted each one by an operator. The fish without the head and the guts - around a 70% of the weight of the fish - is washed in the second machine. It waits into an intermediate buffer to be wrapped by an operator. Finally, it is placed into a box with similar sized HG products (headed and gutted). The full box is ready to go to the freezing stage. Figure 69: Manual Classification of the Fish Figure 70: Wrapped Fish in a Box 206 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. If the fish has an adequate size, it is sent to the fillet lines. Three parallel workstations accomplish the heading, gutting, filleting and skinning of the fish. Each fish yields two fillets that directly go to the skinning, an operation that removes the skin from each fillet. The overall yield is estimated in 40% of the initial weight of the fish. The fillets are the directed to a common belt to be manually put into trays. This operation, the packing, consists on selecting similar sized fillets, trimming them if they still have rests on skin or bones, and place them forming several layers into a tray. A plastic sheet is placed between layers to avoid the adherence of fillets. The full box of fillets goes then to the freezing stage. Figure 71: Packed Fillets in a Tray The fillets can be rejected from the packing operations. This can be because they don’t reach the quality requirements or because the packing operators have not enough capacity to process them. In that case, they go to the block conformation. This third product is a block of fillets weighing 7.5 kg and measuring 485 mm x 255 mm x 63 mm, intended for further processing (breaded sticks, skewered fish, cooked dishes, etc.) 207 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. CH.10: REFRIGERATION PLANT FOR TUNA BAIT 208 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. REFRIGERATION PLANT General Basic refrigeration systems Refrigeration is a process whereby heat is removed and rejected, and this can be achieved by any of the following methods: 1. 2. 3. 4. Vapour compression Vapour absorption Air cycle Thermoelectric The most widely used is the vapour compressions system and only in exceptional circumstances would another method be contemplated in a modern fish processing installation. Even applications which apparently do not use this method, such as chilling with ice or freezing with a cryogenic liquid, are indirect uses of the vapour compression system, since such a system would have been used to make the ice or liquefy the gas. Figure ۷۲: Vapour compression cycle Vapor absorption is still used in some domestic refrigerators and there has been a revival of interest in this system for some commercial applications since it can be operated from a waste heat source. The absorption system does not require mechanical power, therefore, there is no requirement for an electrical supply of direct drive engine. The only requirement is an input of heat, therefore, this type of refrigeration system may be considered for limited applications in situations where a heat source is cheaper or more readily available than an electrical or mechanical drive. The air cycle system is inherently safe and is now almost exclusively used for cabin cooling in aircraft. Design of Stern Trawler 209 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. The thermoelectric cooling system is confined to use with applications which require very small refrigeration effects, such as instrument cooling and laboratory use. Other methods have been used, but they either have not been suitable for commercial operations or have now become obsolete for a variety of other reasons. Cryogenic refrigeration, as mentioned above, is an indirect application of the vapour compression system and liquid nitrogen and liquefied or solid carbon dioxide cryogenic systems have a limited application in fish processing. A high purity fluorocarbon refrigerant, R12, is also used in immersion or spray cooling systems, but again there is only a limited use in the fishing industry. Refrigerants Although there are a wide range of refrigerants available, many have properties which suit them for special purpose applications only. The refrigerants listed in the following Table are those commonly used in the fish industry. And a number of secondary refrigerants, such as ethyl alcohol, methyl alcohol, glycol solutions and salt/sugar solutions, have also a limited use. The choice of refrigerant is usually based on technical requirements, but other considerations, such as safety, high costs or import controls, may result in a compromise choice being made.

Dept. Many of the physical properties of a refrigerant are important to the design engineer and this information is now readily available in suppliers’ catalogues and in text books. Only some of their attributes and likely applications are, therefore, given in the following notes. a. Refrigerant 12: has a relatively low latent heat value and this is an advantage in small machines since the higher flow rates required allow for better control. R12 is usable down to lower temperatures, but below -29.8°C negative pressures will prevail on the lowpressure side of the system with potential problems resulting from leaks of air and moisture. R12 is completely miscible with oil at all likely operating temperatures, therefore, oil return systems are relatively uncomplicated. b. Refrigerant 22: This refrigerant is mainly used as a replacement for R12 at lower evaporating temperatures since a positive pressure will prevail throughout the system down to a temperature of -40°C. It is, therefore, more likely to be used than R12 when there is a requirement to freeze and store fish at temperatures of -25°C or lower. R22 is completely miscible in oil down to a temperature of -9°C, but at lower temperatures there is a separation with oil collecting on the surface of the refrigerant. With the flooded systems used for most fish-freezing operations, special measures will therefore be necessary to return oil from the low-pressure receiver to the compressor. c. Refrigerant 502: This azeotropic mixture of R22 and R115 combines some of the good properties of R12 and R22. For instance, it allows positive pressure operation at lower temperatures like R22, but it has also some of the oil miscibility qualities which are desirable and similar to those of R12. It is, however, costlier and this, together with availability, may be major factors relating to the use of this refrigerant. d. Refrigerant 717 (ammonia): In spite of some of its unfavorable qualities, ammonia is still the most widely used refrigerant for larger installations. In terms of evaporator- operating temperatures, its properties are between those of R12 and R22, and since leaks into an R717 system do not have the long-term damaging effects as those experienced with halocarbon refrigerant systems, R717 is suitable for nearly all fish- freezing and cold storage operations. R717 has a highly irritant effect on the eyes and nose, therefore, small leaks can be readily detected and repaired without the need for systematic testing, as is the case with other refrigerants. In the presence of water, it is corrosive to many non-ferrous metals, therefore, copper, which is widely used with other refrigerants, cannot be used in pipes, evaporators, instruments and controls. R717 forms an explosive mixture when mixed in Design of Stern Trawler 211 Design of a Factory Stern Trawler Naval Arch. and Marine Eng. Dept. the right proportions with air, therefore, special precautions should be taken to avoid the presence of nearby sources of ignition when major leaks occur. The use of R717 may be restricted; for instance, it is not used on fishing vessels in the UK. Oil separates out from R717 at low temperatures and, with the oil being the heavier, it has to be periodically removed from the bottom of the evaporators and low-pressure receivers.
