Auxiliary pumps and motors
Significant reductions in the amount of time spent pumping bilges can be achieved by reducing water leakage from centrifugal and reciprocating pumps and the associated valve and pipe work. In addition, external corrosion and the risk of electrical grounding and burnout will be reduced. Oil seals should be well packaged with appropriate packing and oil seal leakage should be kept to a minimum. Copper cooling and calibration pipes with their associated joints and connections must be leak-tight and in good condition.
Centrifugal pumps should never run dry, and no positive displacement pump should start or run against closed valves. When operating a deck washing system, the bridge should always inform the engine room when they are running low.
heat exchange equipment
Significant loss of heating/cooling capability will occur if deposits (such as marine growth, sludge, and dirt) accumulate on the heat exchangers. Regular cleaning as outlined in the maintenance schedule will reduce this, but monitoring the position of valves or refrigerators/heaters online may indicate deteriorating heat transfer. Increasing the flow rate with additional pumps should be avoided as erosion of the pipes and separating plates may occur.
Bilge pumping (how to get a job on a gas carrier)
Due to the serious nature of oil pollution, the “Law on Oil in Navigable Waters” must be strictly enforced. All mechanics must know and follow the principles set out in the "Guidelines for the Prevention of Marine Pollution by Oil". Please refer to publication MARPOL 73/78.
The oily water separator should always be kept free of oil and the bilge water tank where it is installed should be pumped out ready for use in port whenever possible. Ballast pumps and general purpose pumps should not be used, except in emergency cases, in engine room bilges.
The deck officer must be informed of the intention to pump out the holds. A log entry for any bilge pumping must be made in the engine room log book. Details of bilge water transfer or slurry transfer should be recorded in the "oil book" as required.
Cleanliness of the Engine Room (how to get a job on a gas carrier)
To ensure the smooth and safe running of the vessel, it is important that the engine room is kept as clean as possible. Jerseys and paintwork must be kept clean to
promote early
Detection of potentially dangerous or costly leaks. Oil leaks must be repaired immediately. Cans of hashish must be emptied regularly and all savings must be free of oil. Oil stains on stoves and equipment must be wiped up immediately.
