Stern Tube Sealing
This special type of sealing is arranged to prevent the entry of sea water and also the loss of lubricating oil from the stern bearing.

Shaft LineThe main propulsion shaft line consists of shafting sections connected by means of bolted flange couplings and supported by bearings that keep the shafting in the proper alignment. When in service,the shafting can be checked for static and dynamic alignment. The static check can be done by clocks or strain gauges and the dynamic alignment by measuring the amplitude of axial vibrations at variousspeeds when the ship is underway.


Intermediate Shaft
The intermediate shaft has flanges at each end and is supported by bearings. There may be one or more sections of intermediate shaftingbetween the crankshaft of the main engine and the tailshaft (the propeller shaft), depending upon the machinery space location.

Shaft Line
All the shafting sections are manufactured from solidsteel with integral flanged couplings. The shafting sections are joined by fitted bolts made of solid steel.

Bilge/Fire Pumps and Sea Water Cooling Pumps
All the pumps produce a flow of fluid underpressure. The piping systems are often interconnected and most pumps installed appear in pairs. Pump failures can prove disastrous in case of emergency on board.

ME Lubricating Oil Cooler
Coolerson board ships are heat exchangers where a hot liquid is cooled by sea water. However, fresh water cooling is sometimes used to avoid corrosion problems. The plate-type cooler consists of a number ofsealed titanium plates screwed together into a frame. The plates are extensively corrugated to improve the heat transfer process.

Lub Oil Filters and Separators
The centrifugal separator is used to separate oil and water, or a liquid and solids in the contaminated oil. The separation of impurities and...
