Ship Auxiliary Machineries
 Machinery, other than the main propulsion unit, is usually called 'auxiliary' even though without some auxiliaries the main machinery would not operate for long. The items considered are air compressors, heat exchangers, distillation equipment, oil/water separators, sewage treatment plants and incinerators.
 
Air compressor
Compressed air has many uses on board ship, ranging from diesel engine starting to the cleaning of machinery during maintenance. The air...

 
Pumps and pumping systems
At any one time in a ship's machinery space there will be a considerablevariety of liquids on the move. The lengths of pipework will cover manykilometres, the systems are often interconnecting and most pumps are inpairs. The engineer must be familiar with each system from one end tothe other, knowing the location and use of every single valve. Thevarious systems perform functions such as cooling, heating, cleaning andlubricating of the various items of...

Deck machinery and hull equipment
The various items of machinery and equipment found outside of the machinery space will now be described. These include deck machinery such as mooring equipment, anchor handling equipment, cargo handling equipment and hatch covers. Other items include lifeboats and liferafts, emergency equipment, watertight doors, stabilisers and bow thrusters.
The operations of mooring, cargo handling and anchor handling all involve controlled pulls or lifts using chain...

Flow pattern
  Parallel flow contra flow or counter flow cross flow mixed flow
 
  Contra flow or counter flow heat exchangers are those where the two fluids flow in opposite directions.  (the inlet branch for the fluid passing through the tubes will be adjacent to the outlet branch on the body for the fluid circulating outside the tubes.  Similarly the outlet branch for the fluid passing through the tubes will be...
