Lubrication is a system where all moving machine parts need to be
lubricated, in order to avoid direct friction between the components can cause the
most damage. In motor fuel lubricity do thorough all of the moving parts, and
therefore required the maximum pressure in supporting the work of the auxiliary
engine. The pressure should reach a value of 4.0 to 4.5 kg / cm2 to achieve
maximum lubrication. This prevents the engine when the auxiliary overloaded
then the pressure was not until approaching the limit poor lubrication and an
alarm occurs at a pressure of 3.7 kg / cm2. The author formulates the problem by
searching for the factors of the decline in the cylinder liner lubrication systems,
lubrication systems the impact of falling cylinder liner, and the efforts taken to
address the decline in the cylinder liner lubrication system.
The author summarizes the problems and try to solve the problem by
using the method of hazard operability is with a systematic way of analyzing the
risk of a system whereby the operating activities of potential problems in a system
that is identified using a circuit.
There are many causes less optimal lubrication system maintenance on
auxiliary engines. Among them is happening in MV. Energy Prosperity, of causes
found. In MV. Energy Prosperity less optimal lubrication system so that the
pressure lubricating oil is not normally caused by problems with filters and pumps
and piston cooling case cover, filters and pumps is a component of risky
impending penurunanan pressure and also the influence of the components of the
piston cooling case cover, though not too conspicuous in its work it can cause
lubricating oil pressure is not normal.
