一、系缆设备主要由系缆索、带缆桩、导缆孔(或导缆钳)、绞缆机以及绳车、碰垫等所组成。 二、利用绞缆机收绞缆索，可使船舶系靠。 三、在船首，系缆卷筒和锚机用同一动力，用离合器啮合或脱开

制冷是用人工方法从被冷对象中移出热量，使其温度降低到环境温度以下，在船舶上，制冷技术主要用于以下几个方面：

一、制冷循环分析和计算，常用压焓图和温熵图 二、船用压缩式制冷装置大都使用中、高温制冷剂 三、高温制冷剂 标准沸点t。>0℃的制冷剂属

一、设在厨房附近，尽可能远离机舱，以减少热量渗入 二、 航线较长的大、中型海船大多分设鱼、肉、蔬菜、乳蛋和干货(饮料、粮食)等库。 三、 航线较短的船舶，至少也分设高温库和低温库

一、是在制冷机内完成热力循环的工质,必须具有较好的热力性质和物理化学性质,选用时根据使用场合、温度要求、制冷量及制冷机的型式等综合考虑

船舶驶达港口，常因等候泊位和引水以及接受检 疫、避风或过驳等而需在港外停泊，为能克服停 泊时作用在船体上的水流力、风力和船舶纵倾、 横倾时所产生的惯性力，以保持船位不变，就需 在船上设置锚设备

一、 船载货物的可用港口起货设备来装卸 二、但并非所有港口都具有足够的吊货机械 三、 同时需考虑船舶在开阔水面过驳及吊运物料、备件等的需要

On the morning of 6th October 2002 the French tanker LIMBURG (299,364 DWT) suffered an explosion and fire as she approached the SBM at the Ash Shihr terminal in Yemen. Initially the cause of the explosion and subsequent fire was unclear but it is now considered likely to have been the result of a terrorist attack. Damage was sustained to No. 4 Starboard tank, which at the time contained some

6.6 Coalescing bed-type oily water separators The coalesce is capable of forming oil globules up to l2 mm diameter and the heavier fuel oils usually form long 'stalagmites' which grow to a considerable size before they are released. Because of the 1ow velocities employed the collected oil can flow past the water screen without becoming re-entrained and carried through into the outlet

Principle The rising velocity of the globules carries them upwards where they become trapped by the under-surfaces of the plates and coalesce until the enlarged globules have sufficient rising velocity to travel along the plate surface and break away at the periphery
