5.2 Operation Safety regulations In all centrifugal separators the bowl rotates at a very high speed, normally between 100 and l50 revolutions per second. Thus, very great forces are released and it is essential, therefore, to follow strictly the directions given in the Instruction Book concerning assembly of parts, starting, stopping and overhaul

6.2 Pumping considerations Since the rate of separation depends on the oil globule size it will be appreciated that any disintegration of oil globules in the oily feed to the separator should be avoided and this factor can be seriously affected by the type and rating of the pump used. Tests were carried out by a British government research establishment some years ago on the suitability of various pumps for separator feed duties (Double vane, Triple screw and Single vane )

6.5 Cleaning the Comyn oil/water Separater To clean out the separator ensure that all oil possible has been drawn off through the oil recovery valve and scum valve, and that the separator is full of water. Turn on steam to heating coil; also steaming out connection, and allow the separator to become thoroughly hot

（1) Subject to the provisions of regulations 10 and l1 of this Annex and paragraph (2) of this regulation, any discharge into the sea of oil or oily mixtures from ships to which this Annex applies shall be prohibited except when all the following conditions are satisfied a) for an oil tanker, except as provided for in subparagraph (b) of this paragraph :

A leaking oil tanker split in two and sank Tuesday off Spain's northwestern coast, spewing thousands of tonnes of fuel oil into the sea and adding to a growing environmental disaster along one of Europe's most picturesque and wildlife-rich coasts. The two halves of the 26-year-old single-skinned vessel went down in deep

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

On 29th March the BALTIC CARRIER, a double-hulled chemical tanker, collided with the TERN, a bulk carrier, off the Danish coast, spilling approximately 2700 tonnes of heavy fuel oil. The oil drifted north-westwards from the collision point and started coming ashore during the afternoon and evening of 29th March. The heaviest concentrations were along the south shores of Farøand Bogø in the sound between the islands of Falster

船用泵概述-泵在船上的功用 用来输送液体的一种机械。约36～50台泵/船 液体机械能有位能、动能和压力能三种形式， 它们之间可以相互转换。 机械能量较低的液体是不可能自发地到达机械 能量较高的位置，况且液体在管路中流动还要克 服管路阻力而损失一部分能量

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

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：
