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 be frequently 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.

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 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.

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.

It is essential therefore that the bridge is informed of the location and extent of the fire.A small fire might reasonably be immediately tackled by the finder but attempts should be made whilst fighting the fire to attract attention. Shouting ‘Fire’, banging on bulkheads, deliberately setting off equipment alarms in the vicinity, all are possible means of attracting attention. Anyonefinding a fire must decide whether to fight it immediately or whether to leave it and inform others first. The more people who know of a fire the greater the efforts that can be brought to bear upon it.If in doubt—inform!Ships are built to contain fires in the space where they begin.Fire resisting bulkheads and decks are positioned at appropriate distances in order to limit the spread of fire, and it remains for fire fighting personnel to ensure that these barriers are secure whilst attempting to fight the fire.All doors and openings should be closed, all ventilation and exhaust fans stopped, and flammable material isolated from the space. It should be remembered that a fire exists in three dimensions and therefore has six sides, so it must be contained on six sides.69.According to the passage, once a large fire detected, _____should be informed immediately.A. chief engineerB. bridgeC. masterD. deck officer70.All of the following methods that may possibly be used to give alarms to others in case of a fireare mentioned in the passage except ____.A. shoutingB. banging on bulkheadsC. setting off equipment alarmsD. phoning71.Fire resisting bulkheads and decks provide barriers to______.A. control the spread of fireB. form a room for fire fighting personnelC. secure fire fighting personnelD. isolates fire fighting personnel72.Which one is NOT right for fire fighting?A. doors and openings to be closedB. exhausts fans to be stoppedC. fire to be controlled best in one directionD. flammable material to be isolated第二组:The introduction of invasive marine species into new environments by ships’ ballast water attached to ships’ hulls and via other vectors has been identified by the GEF as one of the four greatest threats to the world’s oceans. The other three are land-based sources of marine pollution, over exploitation of living marine resources and physical alteration/destruction of marine habitat.The I nternational Convention for the Control and Management of Ships’ Ballast Water and Sediments was adopted at an IMO Diplomatic Conference held 9-13 February 2004. Australia signed the Convention, subject to ratification, on 29 May 2005.The Convention will enter in force 12 months after 30 Stateswith combined merchant fleets constituting 35% of the gross tonnage of the world’s merchant shipping have signed the Convention.The Australian Maritime Safety Authority (AMSA) and other responsible agencies have commenced detailed discussions with a view to reaching agreement on how each provision of the new Convention is to be implemented. Work will then commence on the formal consultationprocess and development of a Regulatory Impact Statement.

The pilot pistons are controlled by a cam connected to the camshaft end. When the main starting valve opens, the pilot pistons are pressed onto the cam, whereby the pilot piston for the engine cylinder which is in starting position admits control air to the main piston of the starting valve . The starting air valve opens and admits compressed air into the engine cylinder forcing that piston down. Shortly before the exhaust valves are opened the pilot valve interrupts the control air to the starting air valve and starting air to that cylinder is stopped. This procedure will be repeated as long as the main starting valve is activated or until the engine speed is so high that the engine fires. After the main starting air valve is closed, the main starting air system is de-aerated, the pressure drops quickly and the springs will lift the pilot plungers off the cam. This means that the pilot plungers touch the cam only during the starting process and thus wear is insignificant.If a pilot liner is worn out, press it out. It may be necessary to heat the distributor up till about 200℃ as Loctite is used for fixing and sealing.69.According to the passage, the liners of the starting air distributor ______.A. can be replaced when worn outB. are made of heat resistant materialsC. are welded preciselyD. are worn out easily during the starting process70.During the starting process, when ______, the main starting air valve is closed.A. the exhaust valves in the starting cylinder are openedB. the pilot air to the starting air valve is stoppedC. the engine speed reaches fire speedD. the pilot pistons are pressed onto the cam71.When some cylinder of the engine admits compressed air into it, the pilot piston of the starting airdistributor should be ______.A. separated from the camB. pressed onto the camC. lifted off the camD. pressed onto the cam repeatedly72.From the passage we know that "Loctite" is probably______.A. a type of gasketB. a kind of lubricantC. a glue bondD. an anti-corrosion additive第二组:Maintenance and OverhaulingSatisfactory and proper operation of the engine depends not only on correct maneuvering but also on how well it is kept in order. Regular maintenance of the engine helps a lot in preventingearly 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. Special precaution is necessary when the engine is running with the lagging removed. During overhauls with the engine shut down, safety measures should be taken to avoid undesirable turning of the crankshaft. All pipes should be pressure-relieved before the repair work is started. Read the pressure gauges and /or check the pipes by carefully loosening the screw plugs or connections.If some parts of the running gear are dismantled, before using the turning gear, make sure that no loose parts are jammed in the crankcase where it is easy for them to cause damage.73.According to the passage, which the following factors are involved to keep the engine satisfactoryand proper running?A. correct maneuveringB. keep the engine in orderC. refer to the instruction booksD. all of above74.According to the passage, which the following items do influence the periods of the overhaulingwork?A. the quality of the lubricating oilB. the load of the engineC. the efficiency of the operator in locating troubles and remedying them in timeD. all of the above75.According to the passage, we should take special precaution when ____.A. the engine is running with the removal of laggingB. the engine is shut downC. pipes are removedD. the screw plugs or connections are lossened76.According to the passage, line 17 the bold and italic word “it” may propabably mean ____ .A. running gearB. turning gearC. crankcaseD. to cause damage三、中译英(共2题,请将答案写在答题纸上)77.船东,港口国监督检查中发现,应急消防泵驱动柴油机排气管漏泄,且机旁缺少用工作语言写明的使用说明;机舱固定二氧化碳灭火系统气体释放警报,包括时间延迟继电器在内,在PSC检查中测试不合格,要求立即整改。
