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.

FSS 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Older loop scavenged engines may have a single injector mounted centrally in the cylinder head. Because the exhaust valve is in the center of the cylinder head on modern uniflow scavenged engines the fuel valves (2 or 3) are arranged around the periphery of the head. The pressure at which the injector operates can be adjusted by adjusting the loading on the spring. The pressures at which the injectors operate vary depending on the engine, but can be as high as 540 bar. Some injectors have internal cooling passages in them extending into the nozzle through which cooling water is circulated. This is to prevent overheating and burning of the nozzle tip. Injectors on modern engines do not have internal cooling passages. They are cooled by a combination of the intensive bore cooling in the cylinder head being close to the valve pockets and by the fuel which is re-circulated through the injector when the follower is on the base of the cam or when the engine is stopped. As well as cooling the injector, re-circulating the fuel when the engine is stopped keeps the fuel at the correct viscosity for injection by preventing it from cooling down. Fuel injectors must be kept in good condition to maintain optimum efficiency, and to prevent conditions arising which could lead to damage within the cylinder. Injectors should be changed in line with manufacturers' recommendations, overhauled and tested. Springs can weaken with repeated operation leading to the injector opening at a lower pressure than designed. The needle valve and seat can wear which together with worn nozzle holes will lead to incorrect atomization and dribbling.83. Modern uniflow scavenged engines have .A. a single injector mounted in the center of the cylinder headB. several injectors mounted around the external boundary of the cylinder headC. a single injector mounted at the external boundary of the cylinder headD. several injectors mounted in the center of the cylinder head84. Cooling water is circulated through in some injectors.A. the nozzleB. the nozzle tipC. the internal passagesD. the fuel re-circulated85. Re-circulating the fuel when the engine is stopped can .①keep the fuel at the correct viscosity②cool the injectorA. ①B. ②C. ①②D. neither ① nor ②86. Springs in fuel injectors will become not strong enough to work because .A. the injector opens at a lower pressure than designedB. the needle valve and seat wear outC. the nozzle holes wear outD. long time in use第二组Displacement pumps are those where the volume of the pump chamber is alternately increased to draw the liquid in from the suction pipe and then decreased to force the liquid out into the delivery pipe. Centrifugal pumps are those wherein an impeller rotating at high speed throws the liquid by centrifugal force from the center to the periphery of the impeller where the liquid is discharged through the delivery outlet.Gear pump consists of two or more meshing gears (spur, single or double helical teeth) enclosed m a close-fitted housing. These are used extensively for pumping fuel oil, lubricating oil and hydraulic oil. When gears are unmeshed on the inlet side, a pressure drop occurs that helps the atmospheric pressure acting on the surface of the oil in the reservoir to force it up the pipe to fill the void, the oil is then transferred around the periphery of the pump housing. As the gear teeth mesh again on the outlet side, they form a seal that prevents oil from backing up to the inlet, the oil in the void is then be forced out into the discharge line.All vane pumps have a rotor driven within a ring (cam ring) by a drive shaft coupled to a prime mover. A cylindrical rotor with sliding vanes, generally in radial slots, rotates within the ring. The center of the rotor is offset from the center of the ring. In a simple vane pump, as the rotor turns, the vanes are forced outward against the inner surface of the cam ring by centrifugal force. This outward radial movement of the vanes and turning of the rotor causes the chamber between the vanes to increase as the vanes pass further away from the inlet port. This increase in volume results in a lowering of pressure until the atmospheric pressure is sufficient to force oil from the reservoir into the inlet chamber. Oil from the inlet is swept away by the vanes toward the outlet port through a decreasing series of chambers until it is forced through the outlet port. A vane pump of balanced design has an elliptical cam ring so that two pumping chambers are formed. This pump is in hydraulically balance, since the two intake and two outlet ports are diametrically opposed to each other. Therefore the side loads exerted on the rotor cancel out, thereby increasing bearing lift and permitting high operating pressure.87. According to the last sentence of paragraph 1, from where the liquid is discharged through the delivery outlet?A. from the eye of the impellerB. from passage of impellerC. from the periphery of the impellerD. from the impeller88. Which statement is NOT true?A. In a simple vane pump, the rotor and cam ring are exactly concentricB. Balanced vane pump has an elliptical cam ringC. Liquid in both gear pump and vane pump are forced out to the outlet.D. Balanced vane pumps can work at a higher pressure than the simple vane pump89. Gear pumps are widely used to transfer any one of the following but .A. fuel oilB. lube oilC. hydraulic oilD. fresh water90. Which statement is NOT true?A. While displacement pump works, volume of the working chamber will increase and decrease alternatelyB. A gear pump always has two gears.C. Any vane pump will have a rotor within a ringD. A balanced vane pump has two outlet ports and they are positioned symmetrically.第三组：Ship recycling contributes to sustainable development and is the environmentally friendly way of disposing of ships with virtually every part of the hull, machinery, equipment, fittings and even furniture being re-used. However, while the principle of ship recycling is a sound one, the reported status of working practices and environmental standards in recycling facilities often leaves much to be desired. Such growing concerns about environmental safety, health and welfare matters in the ship recycling industry have resulted in a growing belief that an international instrument to regulate the ship recycling process is urgently needed.Having become aware of the need to reduce the environmental, occupational health and safety risks related to ship recycling, as well as the need to secure the smooth withdrawal of ships that have reached the end of their operating lives, the International Maritime Organization (IMO) has taken action to develop a realistic and effective solution to the problem of ship recycling, which will takeinto account the particular characteristics of international maritime transport and the economic realities.91.

As the air passes through the charge air cooler, its temperature may be reduced and moisture condensed, with the condensate in danger of being carried into the engine. So a water separator should be mounted beneath the bottom part of the engine inlet manifold.Lubricating oil from the compressor will pass along the air lines and deposit on them, in the event of a cylinder air starting valve leaking, hot gases would pass into the air pipes and ignite the lubricating oil. If starting air were supplied to the engine, this would further feed the fire andcould lead to an explosion in the pipelines. In order to prevent such an occurrence, cylinder-starting valves should be properly maintained and the pipelines regularly drained. Also oildischarged from compressors should be kept to a minimum, by careful maintenance.69.A water separator is used in order to ______.A. keep the air from being carried into the engineB. keep the moisture from being condensedC. keep the danger from being carried into the engineD. take away the condensate from the air70.Why should we use a charge air cooler?A.

Air starting valve leaks and starting air is supplied into the engine.C. Cylinder-starting valves are properly maintained.D. Oil discharged from compressors is kept to a minimum.72.In order to avoid igniting the lubricating oil and leading to an explosion in the pipelines, ______.A. pipelines should be regularly drainedB. cylinder-starting valves should be properly maintainedC. oil discharged from compressors should be kept to a minimumD. A+B+C第二组：Maintenance and OverhaulingSatisfactory and proper operation of the engine depends not only on correct manoeuvring but also on how well it is kept in order. Regular maintenance of the engine helps a lot in preventing early wear of parts and in ensuring a long service as well as the working efficiency of the engine.With various types of engines, of course, the maintenance and overhaul is different. Instruction books are to be referred to whenever necessary.The individual parts of the engine should be inspected and thoroughly cleaned at regular intervals. The periods for such overhaul work depend largely on the quality of the lubricating oil and fuel, on the load and on the efficiency of the operator in locating troubles and remedyingthem in time..During overhaul the safety rules have to be observed as required in order to prevent the danger of accidents.

A control system is a system which measures the condition of some entity and, with the information, governs the state of a variable; i.e., speed, temperature, pressure, position, etc. The open-loop system is the simplest form a control system may assume. It is distinguished from the closed-loop system by the lack of an input which measures the state of the controlled variable; such an input is called a feedback. In modern ships the open-loop system has practically disappeared and the closed-loop system which operates with a feed-back is extensively used. An information system serves the parallel function of monitoring system or plant performance. The monitoring function may serve a number of purposes; specifically it may indicate values of controlled variables to guide remote control operations, w arn ofoff-limit conditions and provide record of performance. In many cases a visual and audible alarm may be provided to warn of off-limit conditions on board ship and, associated with this, the important variables will be recorded on demand. The automatic control system can be more sophisticated by incorporating digital-processing equipment, that is, a computer. This computer is usually fed with signals from all sensors. It scans the values of the sensors and generates alarm signals for off-limit conditions, acting as a super-supervisor. Sometimes, it can even make necessary and take the necessary action to optimize performance without human intervention.69. The closed-loop system differs from the open-loop system byA. the lack of a feedbackB. the presence of a feed backC. the lack of a computerD. the presence of a computer70. A feedback is an input ____A. which governs the state of a variableB. which provides a visual and audible alarmC. which indicates values of controlled variablesD. which measures the state of the controlled variable71. The monitoring function may serve all of the following purposes exceptA. instigating corrective actionB. indicating values of controlled variablesC. warning of off-limit conditionsD. providing record of performance72. The word "off-limit" in the passage may mean .A. off-setB. off-stateC. within limitsD. beyond the limit第二组The only attention that heat exchanger should require is to ensure that the heat transfer surfaces remain substantially clean and the flow passages generally clear of obstruction. Indication that undue fouling is occurring is given by a progressive increase in the temperature difference between the two fluids, over a period of time, usually accompanied by a noticeable rise in pressure loss at a given flow.Fouling on the sea-water side is the most usual cause of deterioration in performance. The method of cleaning the sea water-side surfaces depends on the type of heat exchanger. With shell-and-tube heat exchangers, the removal of the header covers or, m the case of the smaller heat exchangers, the headers themselves, will provide access to the tubes. Obstructions, dirt, scale etc., can then be removed, using the tools provided by the heat exchanger manufacturer. Flushing through with fresh water is recommended before a heat exchanger is returned to service. In some applications, such as piston oil cooling, progressive fouling may take place on the outside of the tubes. Most manufactures recommend a chemical flushing pr6cess to remove this in situ~ without dismantling the heat exchanger.Plate heat exchangers may be cleaned by unclamping the stack of plates and mechanically cleaning the surface of each plate as recommended by the manufacturers. The plate seals may require replacement from time to time and here the manufacturers' instructions should be closely followed 73. By which of the following indication, can we conclude that the lube oil-sea water heat exchanger is unduly fouled?A. the heat exchanger lube oil inlet temperature loweringB. the heat exchanger sea-water outlet pressure riseC. the heat exchanger temperature difference between lube oil and sea water increasingD. the heat exchanger pressure difference between sea water inlet and outlet decreasing74. What is the most usual reason for the fresh water-sea water heat exchanger fouling in the sea side?A. lube oil sludge accumulating in itB. dirt and scale etc., formed on the surfacesC. deformation of the tubes and the shell or the platesD. lube oil leakage into sea-water side75. According to the passage, it is recommended that the heat exchanger side be cleaned by .A. flushing with chemical solvent without being dismantledB. brushing mechanically after being disassembledC. flushing with flesh water onlyD. flushing with clean oil only76. According to the passage, which of the following statement is not true?A. the heat exchanging surfaces should be kept substantially cleanB. the heat exchanger flow passages should be clear of obstructionC. seals for the plate heat exchanger needs to be renewed oftenD. the cleaning process of the plate heat exchanger should be done following our experiences only三、中译英（共2题，请将答案写在答题纸上）77. 在船舶以主机“正常全速”运行时，尽管速度设定及压力正常，转速逐渐下降，驾驶台控制立即转换至机旁控制。

The generation of pressure and injection of fuel are not interconnected in a common rail system. Unlike in conventional systems, the injection pressure is independent of the engine speed. Thus there is always full pressure available. The fuel is first stored in the fuel line and then, when a signal is given by the engine controls to the magnetic valves, it is injected into the cylinders. This creates an extremely fine fuel-air mixture which burns particularly efficiently. For the engineers at MAN B&W Diesel the challenge was to apply this injection system to large marine engines - and to adapt it for operation on heavy fuel oil, which means dealing with a fuel heated to approx. 150℃.Reliability and durability are an absolute necessity in engines on sea-going vessels. For this reason the new MAN B&W Diesel common rail engine is especially designed for reliability. The whole system, including the electronic controls is fully redundant, i.e. every major function has a back-up. Thus there are at least two high-pressure pumps to every machine, ensuring that the pressure necessary for fuel injection is available, even if one pump fails. Unlike in most other common rail engines, the MAN injection system is based on conventional pressure-controlled injection. In conventional stroke controlled systems which function with pilot and post-injection, there is a permanently high pressure of 1600 bar, for example, at the needle seat near the combustion chamber. In the MAN B&W system, the pressure on the valve needle is released by means of the solenoid valve controls which is located away from the cylinder !lead, at the common rail accumulator. As a result there is not permanently full pressure on the valve needle seat next to the combustion chamber and the electronic components are protected.By means of CR injection it is possible to control combustion precisely and in within the operating range of the engine flexibly. This lowers the fuel consumption. Optimistic fuel injection also diminishes combustion noise and the exhaust mission of pollutants. Thus soot emission at part loads is for example reduced to a level below the visibility limit. This is becoming increasingly significant in marine applications as the pollutant emission limits are becoming increasingly stringent worldwide. In particular, start-up soot should be avoided. Common rail technology proves a particular advantage at low speeds and when operating conditions change fast, for example in suction dredgers or in cruise liners traveling very slowly in coastal waters.83. Regarding to the common rail system, which statement is NOT true?A. The injection pressure has nothing to do with the engine speedB. The CR used in MAN B&W Diesel engines can deal with heavy fuel oil.C. If electronic controls being used are break down, the whole common rail system will be paralysedD. There are two high-pressure pumps in CR engines.84. Which one is NOT a feature of CR system?A. Main functions have stand-by equipmentsB. Easy to operateC. No combustion noise and low emissionD. Easy to control in different working conditions85. The fuel injection in CR system is .A. stroke-controlledB. pressure-controlledC. speed-controlledD. load-controlled86. According the writer's view, the CR system is most suitable for .A. ocean-going shipsB. suction dredgersC. merchant fleetsD. no information given第二组：The sewage treatment system must be capable of discharging an effluent that comes within the limits of the tests. Sewage can be treated biologically so that it may be discharged with minimal damage to ecosystem. Biological treatment involves the use of living organisms to treat the sewage within the sewage treatment plant so the liquids and sludge discharged are within the standards specified.Biological treatment plants are usually built up as a module and consist of various sections.Waste matter collected from the ships sanitary appliances is led through a sanitary piping system to the treatment module. The solid matter is broken up by passing it through a screen or a series of revolving cutters. The broken up solid material, together with the waste liquid, passes into a tank containing bacteria which require oxygen and a nutrient to propagate. The nutrient is contained in the solid waste material, and oxygen is supplied by bubbling compressed air through the broken up waste. The propagated bacteria change the waste material into a sludge by aerobic digestion. The sludge is finally treated to kill the coliform bacteria before it is passed overboard.When a biological sewage plant is started up, such as when activating a new ship or after cleaning out the tank, a pellet containing bacteria is introduced into the tank. It takes approximately one week for the bacteria to propagate and make the system fully effective. The choice of sanitary appliance cleaners requires extreme care, as many cleaners are toxic to the active bacteria. Once a biological sewage plant is made active it should not be shut down. If it is it will have to be reactivated again because the bacteria will die without a supply of nutrients and oxygen.Bacteria that require oxygen for their survival are referred to as aerobic. Aerobic bacteria are normally used in ships' sewage treatment equipment. Other forms of bacteria that do not require oxygen are referred to as anaerobic. Anaerobic bacteria are used in shore based sewage treatment works where methane is obtained as a by-product for use as fuel.87. This passage is mainly about .A. sewage treatment methodsB. the various sections of a sewage treatment plantsC. biological sewage treatment systemD. how the sewage treatment plants are started up88. Biological treatment may use __ to treat sewage.(1)living organisms (2)chemicals (3)additivesA. (1)B. (2)C. (3)D. (1)(2)(3)89. Sanitary waste matter will .(1)pass through a screen or cutters (2)come into contact with thebacteria in a tank (3)be discharged, normally without bacteriaA. (1)B. (1)(2)C. (2)(3)D. (1)(2)(3)90. According to the passage, the screen or cutters are fitted to __ (1)kill bacteria (2)break up thesolid waste (3)remove solid matter with large sizeA. (1)B. (2)C. (2)(3)D. None of (1)(2)(3) is true.第三组：For a certain provision cooling plant, the capacity regulator is generally controlled depending on pressure, temperature or relative humidity. The pulse emitter is therefore either a pressostat, thermostat or hygrostat. The switching difference of the control units should be rate as large as possible. This applies in particular to control by means Of the pressure, because change to the load in the refrigeration circuit results in relatively quick pressure changes compared to temperature, which can in mm lead to inadmissible oscillation of the regulator.Under partial load, the suction volume and. thus the gas speedcan undergo marked changes depending on the regulation stage.For this reason, the rating and routing of the suction line must begiven particular attention. In order to guarantee sufficient oilreturn, neither full load nor partial load operation may allow thegas speed to fall below a minimum level: 4 m/s in horizontal pipesections; 8 m/s in vertical pipes.For this reason we recommend that vertical pipes be staggeredinto two separate sections (as illustration). As a result of thefalling suction gas speed velocity in partial load operation, the pipe elbow B is blocked by an accumulation of oil. This increases the gas velocity in pipe section A. In order to guarantee adequate oil return, both cross sections must 'be rated so large that the velocity does not fall below the minimum level in full and partial load operation. In plants with extensive pipe systems it is recommended at least for R22 and NH3 to install an additional oil separator.This reduces the oil circulation period and can have positive effects above all for cold starts with relatively high oil ejection.1. According to paragraph 1, if the pulse emitter were a pressostat and its switching difference were set smaller than normal, what would occur for a certain provision cooling plant?A. liquid stroke in compressor during start upB. capacity regulator oscillationC. compressor starts and stops too oftenD. compressor fails to start2. What is the main factor that affecting the oil return from the suction line?A. the load of refrigerating compressorB. the suction volume of refrigerating compressorC. the refrigerant gas speed in suction lineD. the capacity of refrigerating compressor3. According to the passage, which of the following statements is NOT true?A. the oil return is relative easy under partial loadB. the oil return is relative easy under full loadC. the refrigerant gas speed is higher under full loadD. the pipe elbow B is blocked by an accumulation of oil under partial load4. When the refrigerating plant is under full load, the refrigerant gas can return to the compressor through .A. the pipe elbow AB. the pipe elbow BC. both A and BD. either A or B。

Both these motions may cause the ship to head first to one side of its course, and then to the other. This is called yawing. When waves are sufficiently large, the whole vessel may be moved vertically up and down; this is called heave. Large waves passing under the ship from one side impart a side-to-side motion known as sway. The movement of the whole ship ahead and astern is called surge. If the ship is under present at any moment and at any particular place on the surface of the sea are complex, because they are the product of large numbers of different wave motions, of different sizes and moving in different directions, so also the motion of the ship is complex, and is the product of components of each of the six ship motions.93 What does yawing mean in the passage?

The primary responsibility for ensuring that a ship maintains a standard at least equivalent to that specified in international conventions rests with the flag State and if all flag States performed their duties satisfactorily there would be no need for port State control. 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 through Port State Control Officers (PSCOs).69.The purpose of PSC is ______.① to check and inspect foreign ships② to verify the condition of a ship in compliance with requirements of international conventions;③ to make sure that the ship is manned and operated well;④to detain shipsA.①②B.②③C.①③D.①②③④70.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 states71. 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 companies72.PSC inspection is implemented by______ through______.A. flag states/PSCOsB. flag states/ship ownersC. port states/PSCOsD. port states/ship owners第二组:The field current supply in older machines comes from a lower voltage direct current generator or exciter on the same shaft as the alternator. Modern machines however are either statically excited or of the high-speed brush-less type. The exciter is required to operate to counter the effects of power factor for a given load. The power factor is a measure of the phase difference between voltage and current and is expressed as the cosine of the phase angle. With a purely resistance load the voltage and the current are in phase, giving a power factor of one. The power consumed is therefore the product of voltage and current. Inductive or capacitive loads, combined with resistance loads, produce lagging or leading power factors which have a value less than one. The power consumed is therefore the product of current, voltage and power factor. The alternating current generator supplying a load has a voltage drop resulting from the load. When the load has a lagging power factor this voltage drop is considerable. Therefore the exciter, in maintaining the alternator voltage, must vary with load current and also the power factor. The speed change of the prime mover must also be taken into account.73.The word “machines” in the passage refers to _____.A. the direct current generatorB. the alternating current generatorC. the exciterD. the prime mover74.Which of the following statements is true according to the passage ?A. With a purely resistance load, the power factor is zero.B. Inductive loads combined with resistance loads produces leading power factors.C. Capacitive loads combined with resistance loads produces lagging power factors.D. With a purely resistance load, the phase angle is zero.75.When the load has a lagging power factor this voltage drop is considerable. This sentence meansthat _____.A. with a purely resistance load, the voltage drops too muchB. there is a considerable voltage drop in the capacitive load combined with resistance loadC. when the load is the capacitive load combined with resistance load, the voltage drops to zeroD. when the load is the inductive load combined with resistance load, the voltage drop is fairlylarge76.The exciter must vary with:① load current② the power factor,③ speed change of the prime mover.A.①B.②C.①②D.①②③三、中译英（共2题，请将答案写在答题纸上）77.主机以83转/分钟正常航行时，增压器的转速为11700转/分钟，上午10时增压器突然开始产生异常声音，出现振动，主机转速降至60转/分钟, 同时增压器转速降至2400转/分钟。
