It is Jasa Merin (Malaysia) Sdn Bhd intention and policy to operate safe and reliable ships. To this end we have established a Safety inspection program to monitor the safety readiness of the vessels. It is the province of the maintenance department to make the necessary repairs and to maintain safety and other equipment aboard the vessels. The maintenance department is charged with insuring the reliability of the ship’s and the machinery. To do this we employ a combination of planned and predictive maintenance techniques. On the planned maintenance programs:
DRYDOCKINGS - JMM vessels are drydocked every two and half years, thus it is called a biennial drydocking. In the event that a vessel is drydocked in an emergency its next drydocking will be scheduled two and half years after that emergency drydocking.
ENGINE MAINTENANCE - All work recommended by the manufacturer to be done on the prime movers is also planned maintenance. The time basis for this work is generally engine operating hours. In the event that the machinery is idle for long periods of time, real time can become a limiting factor for lube oil and filters also. Engine operating hours are also used to determine engine overhauls. Engine overhaul intervals, tune up intervals, top overhaul intervals, are all listed in the manufacturer’s maintenance recommendations.
PAINT WORK - Vessel deck departments are charged with maintaining the vessels paint work. The Chief Mate can schedule and allocate this work in any way that he wishes so long as a good appearance is maintained.
GENERAL LUBRICATION - This includes greasing of rudders and deck machinery (i.e. anchor windlasses and towing winches). This type of greasing is normally done on a real time basis once a month or once a week for instance.
Predictive maintenance techniques that we employ include:
LUBE OIL ANALYSIS - Lube oil analysis is the back bone of our predictive maintenance system. It supplies us with information regarding where metals, etc. in the lube oil of our operating prime movers and gear boxes. Lube oil analysis has gone into great depth in another section of this manual.
VESSEL INSPECTION - Vessel inspection by based personnel and safety department vessel inspections provide us with invaluable information regarding vessel condition. This information allows us to better plan for drydockings and other maintenance type intervals.
ENGINE INSPECTION - Sometimes called trend analysis the close inspection of a diesel engine reveals what stage the engine is in its useful life. Knowing all the vital signs of a diesel engine allows us to better plan for maintenance intervals.
FEED-BACK AND SUGGESTIONS - Perhaps one of the most valuable sources of information for planning maintenance and predicting maintenance is the feed-back and suggestions that we receive from the field. This includes all the information given to us by vessel engineers, vessel deck officers because these individuals are close to the problem, they are most likely to see the best solution to the problem.
When there is a failure in the maintenance area or in the event that there is human failure, a repair is necessary. The large repairs are normally supervised by based repair supervisors or superintendents. Under normal conditions, however, vessel engineers undertake to repair most of what goes wrong on the vessel.
