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。

Explain the difference between a single-screw ship and a twin-screw ship.2. Describe the function of a ship's anchor and how it is used.答案：1. A single-screw ship is propelled by a single propeller, which is driven by the main engine. It is simpler in designand usually less expensive to build and maintain. A twin-screw ship, on the other hand, has two propellers, each driven by an engine, which can be the same or different. This configuration provides better maneuverability, redundancy in case one engine fails, and often results in higher speeds.2. A ship's anchor is a device used to secure the ship when it is not in motion, particularly in harbors or at sea when the ship needs to be stationary. The anchor is dropped to the seabed, where it digs into the bottom, providing resistance to the ship's movement. The anchor is connected to the。

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.

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.

The inspection consists of visually examining the piston, the rings and the lower part of the cylinder liner, directly through the scavenge air ports To reduce the risk of scavenge box fire, remove any oil sludge and carbon deposits in the scavenge air box and receiver in connection with the inspection.The port inspection should be carried out at the first stop after a long voyage, e.g. by anchoring if possible, to obtain the most reliable result with regard to the effectiveness and sufficiency of the cylinder lubrication and the combustion cycle (complete or incomplete)A misleading result may be obtained if the port inspection is carried out after arrival at harbor, since manoeuvring to the quay and low-load running, e.g. river or canal passage, requires increased cylinder oil dosage, i.e. the cylinders are excessively lubricated, Further, during low load, the combustion ccle might not be as effective and complete as expected, due to the actual fuel oil qualities and service (running) condition of the fuel injection equipment. It is highly recommended to take this information into consideration.89. The components of an engine involved in normal scavenge port inspection comprise _______.①the piston ②piston rings ③the lower part of the cylinder liner④the fuel injectorA.①②B. ①②③④C. ②③D. ①②③90.

A monitor is required to measure these values and provide both continuous records and an alarm where the permitted level is exceeded.The principle used is that of ultra-violet fluorescence. This is the emission of light by a molecule that has absorbed light. During the short interval between absorption and emission, energy is lost and light of a longer wavelength is emitted. 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。

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.
