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 ports through Port State Control Officers (PSCOs).89. The purpose of PSC is ______.①to check and inspect foreign ships②to verify the condition of a ship in compliance with requirements of international conventions③to make sure that the ship is manned and operated well④to detain shipsA. ①②B. ②③C. ①③D. ①②③④90. Who will be responsible for ensuring that a ship maintains a standard at least equivalent to that specified 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 too low, result in the crankshaft rotating more slowly if there is a failure at 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 valve2.the fuel oil pump piston seizing in the barrel. This failure can be ascertained by trying tomove the pump‟s toothed rack.. Defective fuel pumps must be changed.3.the compression being too low because of sticking, worn or broken piston rings4.leaking inlet or exhaust valves5.no clearance in the valve operation gearThe 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 afterthe fuel oil filter.2.the fuel oil primary pump‟s bypass slide valve sticking in the open position3.leaking fuel oil pipes or joints4.water in the fuel oil5.the regulating mechanism being jammed6.the governor not functioning correctly7.the electrical shutdown valve (the monitoring system) being activated93. This passage is mainly about ______.A. the failure of reduced rpmB. 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 ______.①will invariably decrease ②does not decrease ③will decrease under certain circumstancesA. ①B. ②C. ③D. None of ①②③is true95. Which of the following is NOT mentioned as the reason for a cylinder suddenly working at reduced 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 more slowly or stopping?A. changing from heavy oil to light diesel oilB. connections leakingC. there being too much waterD. malfunction of the governor。

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。
