Year: 2001 Language: english Author: Mitsui O.S.K. Lines Publisher: Mitsui O.S.K. Lines Format: PDF Quality: eBook Pages count: 322 Description: We, in the group of Mitsui O.S.K. Lines, currently operate about 500 vessels. According to the statistics of vessel accidents in 2000 contained in data base for MOL-operated vessels (refer to the attached charts), the incidence of accidents (breakdowns which actually affected ships’ schedules or those which had such a potential) was as high as 0.94 case per vessel. Ever since 1996 when statistics were first compiled, about 40% of the accidents which occurred with vessels under our operation, are related to ships’ machinery. It is said that about 80% of accidents with ships are attributed to human error but this statistical figure is not directly applicable to engine-related damage. It is because the engine of a ship is a “man-machine system” operated with man and machinery complementing each other and, as a result, accidents of machinery always involve human beings. The causes of engine accidents are varied, but statistics of engine damage show that structural defects, and problems with design or workmanship, largely account for such accidents. We do not encounter, with a high frequency, cases where the mishandling of equipment and instruments on the part of crew members directly contributed to accidents. There is also a tendency for similar accidents to occur on board many vessels with similar specifications. Essentially, even if it is possible to reduce the number of failures of equipment and instruments or human errors, it is impossible to bring it to “zero”. It is, therefore, important that, in order to prevent accidents, a breakdown or failure, if incurred, be averted from developing into a serious event. This means that crew members are required to recognize abnormal engine conditions as such as early as possible and stop or arrest, in the process, the flow toward degradation of the failure to a seriousaccident. In order to realize that various phenomena (e.g., temperature, sound, pressure, leak, discoloration) which appear in equipment and instruments are signs which may precede subsequent accidents, experience as a professional is naturally required. However, in reality, there is a limit to the experience one engineer can have in the performance of his duties on board vessels. It is, therefore, important to sufficiently analyze accidents which have occurred on board other vessels and utilize such analyses as lessons to prevent accidents of similar kinds. The Marine Engineering Group, Marine Division, shoulders the role to make continued efforts to investigate into causes of machinery damage and, on the basis of such investigations, determine guidelines for the operation of engines on board vessels under our operation. This time, we have put a large number of engine trouble cases in perspective in terms of the cause, countermeasure and lesson, to compile this set of “Engine Accident Cases”. We request you to take full advantage of this material for training those who embark vessels under MOL’s operation as engineers, thereby to prevent the occurrence of engine-related accidents.
