ISPS Code二、关联题(关联题题干下有4个小题,每小题4个选项)第一组: The Wartsila 50DF operates on the lean-bum principle: the mixture of air and gas in the cylinder has more air than is needed for complete combustion. Lean combustion reduces peak temperatures and therefore NOx emissions. Efficiency is increased and higher output is reached while avoiding knocking. Combustion of the lean air-fuel mixture is initiated by injecting a small amount of LFO (pilot fuel) into the cylinder. The pilot fuel is ignited in a conventional diesel process, providing a high-energy ignition source for the main engine. To obtain the best efficiency and lowest emissions, every cylinder is individually controlled to ensure operation at the correct air-fuel ratio and with the correct amount and timing of pilot fuel rejection. Wartsila has developed a special electronic control system to cope with the demanding task of controlling the combustion in each cylinder, and to ensure optimal performance in terms of efficiency and emissions under all conditions by keeping each cylinder within the operating window. Stable and well-controlled combustion also contributes to less mechanical and thermal load on the engine components. Current stringent emission regulations demand the reduction of NOx emissions. In an internal combustion engine this means controlling peak temperature and residence time, which are the main parameters governing NOx formations. In the Wartsila 50DF engine, the air-fuel ratio is very high (typically 2.2). Since the same specific heat quantity released by combustion is used to heat up a larger mass of air, the maximum temperature and consequently NOx formation are lower. The mixture is uniform throughout the cylinder since the fuel and air are premixed before introduction into the cylinders, which helps to avoid local NOx formation points within the cylinder. Benefiting from this unique feature, NOx emissions from the Wartsila50DF are extremely and comply with the most stringent existing legislation.83. What is the combustion feature of the Wartsila 50DF?A. Lean air in the cylinderB. Excessive fuel in the cylinderC. Excessive air in the cylinderD. Spark ignition84. For the Wartsila 50DF, the complete combustion compared with the lean-combustion can decrease the following results .①Exhaust temperatures ②NOx emissions ③Propeller efficiency ④Output⑤Cylinder knocking ⑥Fuel supplyA.①②B. ③⑥C. ④D.④⑤85. Which system should be supplied to obtain the best efficiency and lowest emissions?A. Lean combustion principleB. Fuel oil systemC. Electrical control systemD. Electronic control system86. What is the most advantage of the lean-combustion different from the routine combustion?A. Continue runningB. Well combustionC. Higher peak temperatureD. Lower holding time of Maximum temperature第二组:Magnetic pickup (MPU) sensors are devices which can be used in conjunction with electronic control modules for monitoring of parameters such as speed, direction of rotation and a variety of alarm conditions. MPU sensors are available in various sizes and types. Following are some guidelines for their selection on industrial engines. MPUs are located near a flywheel, camshaft or other type of gear with rotation relative to engine speed. The passing of the gear teeth through the MPU tip (pole) generates a voltage and frequency. This frequency is converted to a speed reference by a control module. It should be noted here that most MPUs will develop similar signals. However, the magnitude and strength of the signal is dependent on the size of the sensor in relation to the gear teeth, the clearance between the pole piece and the gear teeth, and various other factors. As a general rule of thumb, the following standards should be met:①Dimension of tooth top surface should be equal to or more than the pole piece diameter.②Tooth height should be equal to, or more than the space between teeth.③The space between teeth should be approximately three times the pole piece diameter.④Air gap (clearance) between tooth and pole piece should be between 0.015" to 0.030". MPUs normally have 3/8", 5/8" threads and 2", 3" and 4" lengths. Determining which size is appropriate depends on the space available for installation, the availability of pre-drilled holes and consideration to those rules mentioned above. In most cases, these will be the only factors affecting the selcetion of a MPU.87. MPUs can be used to .①sense speed ②supply alarm ③sense direction of rotation.A.①②B. ②③C. ①③D. ①②③88. Which of the following factors will affect the strength and magnitude of the signal?A. The number of the gear tooth.B. The clearance between the pole pieces.C. The size of the sensor.D. The MPUs thread.89. According to the passage, we can infer that the pole piece diameter must be tooth height.A. as same asB. much less thanC. much more thanD. not confirmed90. Which of the following factors will affect the selection of a MPU? ①the pole piece length ②the availability of pre-drilled holes ③the space available for installation.A. ①②B. ②③C. ①③D. ①②③第三组:Following a security incident, in which the response measures outlined in the Ship Security Plan (SSP) have been activated, there will be a thorough review of their effectiveness and details will be made available, on request, to persons duly authorized by the Ship's Flag State Administration. The Ship Security Plan is not subject to detailed inspection (other than confirming its existence on the ship) by duly authorized officials of a port State unless there are "clear grounds" to believe that the ship is not in compliance with the requirements of SOLAS or the ISPS Code, and the only means to verify or rectify the non-compliance is to review the relevant sections of the Plan. In such cases, access to the Restricted parts of the Plan relating to the non-compliance is exceptionally allowed, but only with the consent of the Flag State, or the master. If the master, in his professional judgment, believes that such "clear grounds" exist, and allowing access to relevant sections of the Restricted part of the Plan might resolve the situation, such access can be exceptionally granted. However, this should be immediately reported by the ship to the Company Security Officer (CSO). If access to the Restricted part of the Plan is denied by the master, this should be immediately reported by the ship to the Company Security Officer for guidance and reference to the Flag State.The Confidential part of a SSP cannot be subject to non-flag State inspection unless otherwise agreed by the contracting governments concerned. Any such request or demand by port state officialsto view sections of the Confidential part of the Plan will be immediately reported by the ship to the Company Security Officer for guidance and reference to the flag State before any details are revealed to non-flag State officials. The Confidential provisions, which from an integral part of this Plan, are held by the Ship Security Officer (SSO)91. After a security incident, the revision of the SSP will made by .A. the CSOB. the SSOC. persons duly authorized by the Ship's Flag State AdministrationD. information not given92. Which statement is True?A. The Port State Control Officer has no right to check a SSPB. The Master has the right to refuse the request from a Port State Control Officer to check theconfidential part of the SSP on boardC. The Confidential part of a SSP can never be subject to non-flag StateD. Even the flag State has no right to check the SSP thoroughly93. The Restricted parts of a SSP are kept on board byA. the CSOB. the SSOC. the Flag StateD. the master94. After the SSP being checked by a duly authorized officials of a port State, whom should be reported to by the ship immediately?A. Port StateB. Flag stateC. The CSOD. The Administration。

FSS Code二、关联题(关联提题干下有4个小题,每小题4个选项)第一组:In a closed fresh water system, the engine jackets, the heat exchanger and the circulating pumps form a continuous circuit which is not open to the atmosphere. The cylinder jacket cooling water after leaving the engine passes to a sea water circulating cooler (heat exchanger) and then into the jacket water circulating pumps. It is then pumped around the cylinder jackets, cylinder heads, exhaust valves and turbo-blowers. However, provision has to be made for the expansion of the water due to the increase in temperature and due to small amounts of air which may enter the system and become entrained and for water make-up due to leakages. These are met by a small head tank which is open to the atmosphere and placed at a higher level than any other point in the system so that the small changes in volume can be accommodated by changing the level of the free surface of the water in the tank. The head tank is generally connected into the system at the pump suction, as this minimizes the chance of air being draw into the system at the pump. The minimum height of the head tank may be based on maintaining pressure of fresh water in the heat exchanger above that of the seawater to ensure that in the event of a small internal lock developing seawater cannot enter the fresh water system. Alternatively, it may be based on the need for a minimum pressure to be maintained within the jackets to avoid cavitations effects. The closed systems usually need vents if steam pockets or air locks are not to cause trouble. V ent pipes of small-bore tube are lead from any local high point in the system to the top of the head tank for the release of air from the cooling water. A heater in the circuit facilitates warming of the engine prior to starting by circulating hot water. The temperature of the water entering the engine jackets is regulated by means of a by-pass across the jacket water cooler. The proportions of water passing through the cooler, or bypassing it are controlled by a three-way valve. The temperature is usually adjusted to maintain a constraint outlet water temperature from the engine regardless of the load or speed or the temperature of the seawater. The piston cooling system may be an open system which employs similar components with the closed system, except that a drain tank is used instead of ahead tank and the vent are then led to a hopper or tundish at the high point in the machinery space. The hopper serves as a visual flow indicator. A separate piston cooling system is used to limit any contamination from piston cooling glands to the piston cooling system only.89. The loop of the jacket cooling water is ______A. engine----heat exchanger----circulating pumps-----engineB. heat exchanger-----engine----circulating pumps----heat exchangerC. circulating pumps----heat exchanger-----engine-----circulating pumpsD. circulating pumps----engine-----heat exchanger----head tank90. A small head tank is provided in the closed jacket cooling water system for _____A. water expansionB. water make-upC. warming of the engineD. water expansion and make-up91. The head tank is connected to the closed circuit at _____A. engine inletB. pumps inletC. heat exchange inletD. engine outlet92. The jacket water temperature is regulated to maintain a constraint temperature of ___A. engine inletB. pumps inletC. heat exchanger inletD. engine outlet第二组Following a security incident, in which the response measures outlined in the Ship Security Plan (SSP) have been activated, there will be a thorough review of their effectiveness and details will be made available, on request, to persons duly authorized by the Ship’s Flag State Administration. The Ship Security Plan is not subject to detailed inspection (other than confirming its existence on the ship) by duly authorized officials of a port State unless there are “clear grounds” to believe that the ship as not in compliance with the requirement of SOLAS or the ISPS Code, and the only means to verify or rectify the non-compliance is to review the relevant sections of the Plan. In such cases, access to the Restricted parts of the Plan relating to the non-compliance is exceptionally allowed, but only with the consent of the Flag State, or the master, If the master, in his professional judgment, believes that such “clear grounds” exist, and allowing access to relevant sections of the Restricted part of the Plan might resolve the situation, such access can be exceptionally granted. However, this should be immediately reported by the ship to the Company Security Officer (CSO). If access to the Restricted part of the Plan is denied by the master, this should be immediately reported by the ship to Company Security Officer for guidance and reference to the Flag State.The Confidential part of a SSP cannot be subject to non-flag State inspection unless otherwise agreed by the contracting governments concerned. Any such request or demand by ort state officials to view sections of the confidential part of the Plan will be immediately reported by the ship to the Company Security Officer for guidance and reference to the flag State before any details are revealed to non-flag State officials. The Confidential provisions, which from an integral part of this Plan, are held by the Ship Security Officer (SSO)93.

The hydraulic servomotor is actuated by a hydraulic circuit and controlled by control valves.CPP in large vessels are usually fitted with combinatory controls on the bridge. These are single-lever controls, the single lever controlling both propeller pitch and engine speed, either through pneumatic circuits operated by cams driven by a common shaft, or by electronic means.In either case closed loop circuits are employed, so that feedback, of propeller position and of engine speed, balances off the control signal.Additional control stands are often fitted on the bridge wings. These are commonly “slaves” to the main central bridge control stand.It is usual practice to take control of both engine and CPP by separate levers in the MCR after starting machinery, switching to bridge control from the MCR before leaving harbour. It follows that the consoles housing power supplies etc. for the CPP controls are generally fitted in the MCR.75.The blade palms of a large CPP are operated by______.A.the hubB.a hydraulic servomotorC.push rodsD.a crankpin-sliding block mechanism76.Which statement is NOT correct regarding to the single-lever controls?A.

Oil fluoresces more readily than water and this provides the means for its detection.A sample is drawn off from the overboard discharge and passes through a sample cell. An ultra-violet light is directed at the sample and the fluorescence is monitored by a photoelectric cell Where an excessive level of contamination is detected an alarm is sounded and diverting valves are operated. The discharging liquid is then passed to a slop tank.93. The passage is mainly about ________.A. oily water separatorB. current regulations related to oil pollutionC. oil in water monitorD. the principle of ultra-violet fluorescence94. A monitor can obtain all of the following functions except _______.A. measuring oil content valuesB. providing continuous recordsC. lowering the oil content below 15 ppmD. providing an alarm unit warning of levels of discharge in excess of 15 ppm95. From the passage, we can learn that the ultra-violet fluorescence is a kind of________A. oil sampleB. lightC. photoelectric cellD. alarm unit96. A sample is drawn off from ______ and passes through a sample cellA. bilge waterB. discharge of oil separatorC. slop tankD. discharge of oily water separator。

Talk about the equipment in engine room.There are all kinds of equipment in a typical engine room, such as themain engine, the auxiliary engine, the boiler, the oil separator, the fresh water generator, the incinerator, the oily water separator, all kinds of pumps and so on.The main engine is the most important one of all the equipment. It is usually a two-stroke low speed diesel engine. The auxiliary engines are usedto drive the alternators. They are usually four-stroke trunk piston engines. The steam on board is produced by the boiler. There are two distinct types about marine boilers in use, the fire-tube boiler and the water-tube boiler. The fresh water generator produces fresh water by evaporation of sea water. It can also be called an 'evaporator' or3'distiller'. A vacuum boiling evaporator consists of an evaporatingsection and a condensing section. The incinerator and the oily water separator are pollution prevention equipment in the engine room.2. The main engine in our engine room.The main engine is the most important one of the equipment in our department. It is a two-stroke low speed marine diesel engine. The main engine is used to drive the propeller. Because of low speed, it requires no reduction gearbox between it and propeller.In general, the main engine consists of two parts: the moving parts andthe fixed parts. The moving parts are also called the driving gear. These include the crankshafts, the connecting rods, the crossheads and the pistons. Among the fixed parts there are the bed plates, the frames, the main bearing and the cylinders. In addition to these main parts, the necessary system that should be used to run the main engine is fuel oil system, starting air system and cooling water system.We take good care of the main engine to ensure its good working condition. Everyday during the watch we note and verify the parameters of the main engine.And verify the parameters of the main engine. And at appropriate intervals we inspect it carefully.3. Look at the illustration and say something about the marine diesel engine.This marine diesel engine is two-stroke diesel engine. The scavenging method is uniflow scavenging. It is pressure charged.A marine diesel engine can be divided into two parts, the moving parts and the fixed parts. The main moving parts of the marine diesel engine are the piston, the connecting rod, the crankshaft and the piston rod. The main fixed parts of the marine diesel engine are the bedplate, the frame, the main bearing and the cylinder.In additional to these main parts, the necessary systems that should be used to run the diesel engine are fuel oil system, lubricating oil system, starting air system and cooling water system. These systems are very important to the marine diesel engine. Its successful operation and trouble free life depend on these systems.The diesel engine is a type of internal combustion engine. The marine diesel engine is a type of diesel engine used on ships.The operation between two injections is called a cycle. This cycle may be achieved either in four strokes or two. In a four-stroke diesel engine, the cycle requires four separate strokes of the piston. They are suction, compression, expansion and exhaust. If we combine the suction and exhaust operations with the compression and expansion strokes, the four-strokes, the four-stroke engine will be turned into a two-stroke one.When the air is compressed, its temperature rises so that it ignites the fine spray of fuel injected into the cylinder. The burning of the fuel adds more heat to the air charge, causing it to expand and force the engine piston to do work on the crankshaft. Then the crankshaft in turn drives the ship's propeller.4. Look at the illustration and say something about the working cycle of the marine diesel engine.This is the exhaust turbo-charging illustration of a two-stroke of marine diesel engine.. As the air4density determines the maximum weight of fuel that can be burned. It also determines the maximum power that can be developed by the engine. If the charge-air density is increased by a compressor, a greater amount of fuel can be burned and result in an increase of power output.From the illustration, we can see that: The compressor is driven by the heat energy obtained from the engine exhaust gases. The gas-turbine is driven by the engine exhaust gases and directly coupled to the compressor (blower). The blower then draws fresh air from the engine-room and discharges it into the air inlet manifold on the engine. The air is pumped into the cylinder through the inlet ports. When air is burned, it becomes exhaust gases and discharge from the discharge valve which is on the top of combustion space. The exhaust gases then drive the compressor as describe above.The charge-air cooler is fit after the passage of compressor. Here,charge-air is cooled by cooling water and its density increases. Because the amount of air flowing into the cylinders is increased and as the charge-air temperature lowers, it is not only power output is increased, but also the exhaust temperature and the engine thermal load are reduced.5. Look at the illustration and say something about the exhaust gas turbocharger and supercharging.With supercharging a large mass of air is supplied to the cylinder by blowing it in under pressure. The exhaust gas turbocharger is the most commonly used on board to increase the density of the charge air.The exhaust gas turbocharger is composed of five parts: the air manifold, the exhaust manifold, the turbine, the compressor and the charge air cooler.The principle is as following: the exhaust air from the exhaust manifold enters the turbine room. Inertia of exhaust air drives the turbine. Theturbine is rigidly coupled to a centrifugal type air compressor. Then by the use of the compressor, the increase in charge air density is accomplished. Both four-stroke and two-stroke cycle engines may be pressure charged. The supercharging does a great favor to the thorough burning of the fuel. Then the output power is increased.The exhaust gas turbocharger is very important. We must pay attention toit and ensure its good working condition.6. Look at the illustration and say something about the cooling water system.The cooling water system is made up of jacket cooling water system and piston cooling water system. The coolant used in the cooling water system is fresh water. Cooling enables the engine metals to retain their mechanical properties.The main devices in the cooling system are expansion tank, jacket cooler, LO cooler, piston cooler, piston cooling water pump and so on. After leaving the engine, the jacket cooling water passes partially to the cooler and then into the jacket cooling water pumps, it is then pumped around the jacket.The expansion tank can ensure the jacket against cavitations effects. It can make up water due to leakages in the system. It can also ensure that the sea water can’t enter the fresh water system in the event of a small leakage in the jacket cooler.The cooling water system is very important. We must ensure it’s in good order and maintenance.5感谢您的阅读,祝您生活愉快。

Unfortunately this is not the case as evidenced by the many marine accidents around the world-hence the need for additional control.The authority for exercising PSC is the national law based on relevant conventions. It is therefore necessary for a port State to be Party to those conventions and to have promulgated the necessary legislation before exercising PSC. In accordance with the provisions of the applicable conventions, Parties may conduct inspections of foreign ships in their ports. They are Port State Control Officers (PSCO).89. The purpose of PSC is _________.1) to check and inspect foreign ships2) to verify the condition of a ship in compliance with requirements of internationalconventions.3) to make sure that the ship is manned and operated well4) to detain shipsA. 1) +2)B. 2)+3)C. 1)+3)D. 1)+2)+3)+4)90. Who will be responsible for ensuring that a ship maintains a standard at least equivalent to thatspecified in international conventions?A. PSCOsB. Ship ownersC. Flag statesD. Port states91. Before exercising PSC, a port state should __________.A. become a contracting Party and promulgate regulations for implementing PSCB. inform ship ownersC. establish proceduresD. inform shipping companies92. PSC inspection is implemented by ________through _________.A. flag states/ PSCOsB. flag states/ ship ownersC. port states/ PSCOsD. port states/ ship owners第二组Almost all failures in the fuel oil system, including the compression being to low, result in the crankshaft rotating more slowly if there is a failure at one or more cylinders simultaneously. If only one or two cylinders fail, and the engine is not fully loaded, the crankshaft rev./min. does not decrease, the reason being that the governor ensures that the remaining cylinders are loaded to a correspondingly greater extent. If the engine is already fully loaded, the cylinders that are working normally become overloaded causing a smoking exhaust and higher exhaust temperatures etc. The load must always be reduced until the failure has been located and rectified. The reasons for a cylinder suddenly working at reduced load, or failing completely, may be:1. a defective or blocked fuel injection valve.2.the fuel oil pump piston seizing in the barrel. This failure can be ascertained by trying to movethe pump‟s toothed rack. Defective fuel pumps must be changed.3.the compression being to low because of sticking, worn or broken piston rings.4.leaking inlet or exhaust valves.5.no clearance in the valve operation gear.The reasons for the crankshaft rotating more slowly, or stopping completely, can also be:1.the fuel oil filter being blocked. This failure is identified by decreasing oil pressure after thefuel oil filter.2.valve sticking in the open position.3.leaking fuel oil pipes or joints.4.water in the fuel oil.5.the regulating mechanism being jammed.6.the governor not functioning correctly.7.the electrical shutdown valve (the monitoring system) being activated.93. This passage is mainly about ________.A. the failure of reduced rpm.B. the failure of the governorC. how to ensure the constant rotational speedD. the reasons for the fuel system to shut down94. If one or two cylinders fail in fuel oil system the crankshaft rev/min __________.1) will invariably decrease 2) does not decrease 3) will decrease under certaincircumstancesA. 1)B. 2)C. 3)D. None of 1),2),3) is true95. Which of the following is NOT mentioned as the reason for a cylinder suddenly working atreduced load?A. fuel valve failureB. failure of fuel pump discharge valvesC. too large gaps of piston ringsD. the fuel oil filter being blocked completely96. Which of the following is NOT mentioned as the reason for the crankshaft rotating moreslowly or stopping?A changing from heavy oil to light diesel oilB. connections leakingC. there being too much waterD. malfunction of the governor。

The main starting valve can be locked shut and this must be done before the engine mining gear is engaged. When this valve is open, air passes through a non-return valve and flame arrester to the main manifold supplying pressure to the cylinder valves.one of which is fitted to each cylinder of the engine・The cylinder air start valves are normally held closed by a compression spring together with cylinder pressure acting over the calve lid.air from the manifold enters these valves where it forms a pressure balance between the underside of the valve lid and a balance piston of equal area on the vale spindle. Consequently this does not cause the valve to open.cylinder valves are opened when operating air, transmitted from the distributor, applies pressure to the larger operating piston on the valve spindle. As the valve is force open , starting air from the manifold enters the cylinder, applying pressure on the piston and causing the engine to rotate in the corresponding direction. To close the cylinder calves the connection from the distributor is opened to atmosphere, allowing the spring to close the valve and return the operating piston.75.The timing valves(in the first paragraph) refer to ____ .A.

With good management, to facilitate subsequent starting from cold, the fuel system of large boilers will have been flushed through with diesel oil when the boiler was on light duty immediately prior to being secured. When burning such diesel fuel it is essential for safety that only the correct (small) burner tip should be used. It should be kept in mind that if fire does not light, immediately shut off fuel and vent furnace.Complete ignition of fuel in the furnace is essential. The burner flame, the smoke indicator and the funnel should befrequently observed. With satisfactory combustion, the flame should appear in candescent (白热的)with an orange shade at the flame tip, and a faint brownish haze should show at the funnel. If on first ignition the flame is uncertain, badly shaped and separates from the primary swirler, momentary opening or closing of air register may correct.75.

This is achieved by the superior combustion performance with the common-rail fuel injection.This system maintains the fuel injection pressure at the optimum level right across the engine speed range, ensuring optimum combustion under all operating conditions. In addition, a selective shut-off of single injectors at very low speeds and an optimized exhaust valve timing help to keep smoke emissions below the visible limit.Sulzer RT-flex engines also have the advantage of steady running at lower speeds than engines with mechanically-controlled injection. They can run very steadily, andwithout smoking, at 10-12% of nominal speed, which for the RT-flex 60C is about 10-14rpm. This is made possible by the precise control of injection, together with the higher injection pressures achieved at low speed, and the sequential shut-off injectors.75.According to above massage, the advantage of common-rail injection is______.A. smokeless operationB. shockless operationC. noiseless operationD. no vibration operation76.According to above massage, RT-flex engine can optimize______.① fuelinjection pressure ② combustion ③ exhaust valve timingA.①②B. ①②③C..③D. ②77.The key feature of the Sulzer RT-flex system is that it gives complete freedom inthe _____ and operation of fuel injection and exhaust valve actuation.A. meteringB. timingC. controlD. using78.The RT-flex engine can run at very low speed, this is made possible byfollowing things except _______.A. the precise control of injectionB. the higher injection pressuresC. the optimized exhaust valve timingD. the sequential shut-off injectors4三、中译英(共2题,请将答案写在答题纸上)79、(轮机日志)上午10时30分,由于不明原因运行中NO.1发电机跳闸,导致全船失电, NO.2发电机自动起动恢复正常供电。

FSS Code二、关联题(关联提题干下有4个小题,每小题4个选项)第一组:In a closed fresh water system, the engine jackets, the heat exchanger and the circulating pumps form a continuous circuit which is not open to the atmosphere. The cylinder jacket cooling water after leaving the engine passes to a sea water circulating cooler (heat exchanger) and then into the jacket water circulating pumps. It is then pumped around the cylinder jackets, cylinder heads, exhaust valves and turbo-blowers. However, provision has to be made for the expansion of the water due to the increase in temperature and due to small amounts of air which may enter the system and become entrained and for water make-up due to leakages. These are met by a small head tank which is open to the atmosphere and placed at a higher level than any other point in the system so that the small changes in volume can be accommodated by changing the level of the free surface of the water in the tank. The head tank is generally connected into the system at the pump suction, as this minimizes the chance of air being draw into the system at the pump. The minimum height of the head tank may be based on maintaining pressure of fresh water in the heat exchanger above that of the seawater to ensure that in the event of a small internal lock developing seawater cannot enter the fresh water system. Alternatively, it may be based on the need for a minimum pressure to be maintained within the jackets to avoid cavitations effects. The closed systems usually need vents if steam pockets or air locks are not to cause trouble. Vent pipes of small-bore tube are lead from any local high point in the system to the top of the head tank for the release of air from the cooling water. A heater in the circuit facilitates warming of the engine prior to starting by circulating hot water. The temperature of the water entering the engine jackets is regulated by means of a by-pass across the jacket water cooler. The proportions of water passing through the cooler, or bypassing it are controlled by a three-way valve. The temperature is usually adjusted to maintain a constraint outlet water temperature from the engine regardless of the load or speed or the temperature of the seawater. The piston cooling system may be an open system which employs similar components with the closed system, except that a drain tank is used instead of a head tank and the vent are then led to a hopper or tundish at the high point in the machinery space. The hopper serves as a visual flow indicator. A separate piston cooling system is used to limit any contamination from piston cooling glands to the piston cooling system only.89.

The Ship Security Plan is not subject to detailedinspection (other than confirming its existence on the ship) by duly authorized officials of a port State unless there are “clear grounds” to believe that the ship as not in compliance with the requirement of SOLAS or the ISPS Code, and the only means to verify or rectify the non-compliance is to review the relevant sections of the Plan. In such cases, access to the Restricted parts of the Plan relating to the non-compliance is exceptionally allowed, but only with the consent of the Flag State, or the master, If the master, in his professional judgment, believes that such “clear grounds”exist, and allowing access to relevant sections of the Restricted part of the Plan might resolve the situation, such access can be exceptionally granted. However, this should be immediately reported by the ship to the Company Security Officer (CSO). If access to the Restricted part of the Plan is denied by the master, this should be immediately reported by the ship to Company Security Officer for guidance and reference to the Flag State.The Confidential part of a SSP cannot be subject to non-flag State inspection unless otherwise agreed by the contracting governments concerned. Any such request or demand by ort state officials to view sections of the confidential part of the Plan will be immediately reported by the ship to the Company Security Officer for guidance and reference to the flag State before any details are revealed to non-flag State officials. The Confidential provisions, which from an integral part of this Plan, are held by the Ship Security Officer (SSO)93.
