【正文】 e various equipment and devices safely, and introduce as much safety knowledge as I can.4. Please describe the work on board.As the engineer officer in charge of watch, my daily work on board is as follows: I shall ensure that the main propulsion plant, auxiliary machinery and steering gear are in good order. The current operational parameters of all machinery should be observed, such as the exhaust gases temperature of main engine, the cylinder jacket outlet cooling water temperature and pressure etc. During watch, the bridge orders must be carried out right now. Any abnormal parameters in relation to the equipment should be paid attention.Lesson 4Task31. Talk about the auxiliary machinery in the engine room.The auxiliary machinery is much more in number. They are not as big as the main engine. They include the generators, the boilers, the fresh water generators, the pumps and the steering gear, the windlass, the winches and cranes. They are very important for voyage. Without them, the ship can’t sail at sea.2. Describe the two types of boilers on board.There are two distinct types of marine boilers in use on board ship, the firetube boiler in which the hot gases from the furnaces pass through the tubes while the water is on the outside, and the watertube boiler in which the water flows through the inside of the tubes while the hot furnace gases pass around the outside. The watertube boiler is employed for high pressure, high temperature, high capacity steam applications, . providing steam for main propulsion turbines or cargo pump turbines. Firetube boilers are used for auxiliary purposes to provide smaller quantities of low pressure steam on diesel engine powered ships.3. Talk about oil treatment.Both fuel oil and lubricating oil require treatment before passing to the engine. This will involve storage and heating to allow separation of water present, coarse and fine filtering to remove solid particles and also centrifuging. Lesson 5Task33. Say something about the function and management of ballast water.The ballast water is used to ballast or trim the vessel. The ballast system is arranged to draw water from any tank or the sea and discharge it to any other tank or the sea. When transferring ballast water from one tank to another, we must pay much attention. Open the related valves correctly. Close other valves start the pump. Otherwise we could not pump the water. we must ask for the permission from the port authorities before discharge ballast water or we’ll be fined.Lesson 6Task31. Say something about the maintenance work of electrical equipment.Cleanliness is essential for good operation of the electrical equipment. Electrical connections must be sound and any signs of sparking should be investigated. Parts subject to wear must be examined and replaced when necessary. Care must therefore be taken to ensure isolation of equipment before any inspection or maintenance is undertaken. Regular insulation resistance measurement and the piling of records must be taken to protect the electrical equipment.2. Talk about the importance of water on board.The water is used widely on board. Without water, The seaman can’t live and the engine also can’t operation fresh water is used for drinking water、toilet、boiler water. The sea water used for coolant、sanitary、extinguisher、ballasting and so on.Lesson 7Task31. Talk about the telegraph in the engine room.The telegraph is on the control room console. It is used to control and indicate the Main Engine condition. On the telegraph, two directions are shown, that is, ahead and astern, and between them is the stop position. Every time before sailing, this telegraph must be checked. It should have no difference with the bridge telegraph.2. Talk about the engine room orders.Any engine order given should be repeated by the person operating the bridge telegraph and the engineer on watch should ensure the order is carried out correctly and immediately. The engine orders include:Stand by engine。rags,聽力100分 看圖/讀句選單詞 單句選相近意思的選項(xiàng) 聽一段對(duì)話/文章選問題口語會(huì)話100分 讀文章20分 抽取topic 20分 10個(gè)問答題每個(gè)6分問答題Lesson 1Task2 is your name？My name is Wang Wei.2.
