Abstract:According to the regulations of the international congress, ship registration and ship classification, every ship has to pass the necessary surveys and to be certificated its seaworthiness, then being able to sail to all ports over the world. Ship surveys consist of six kinds, i.e. annual survey, intermediate survey, special survey, dry docking, occasional survey, and extension survey. Their implementing terms form a five-year cycle. The arrangement of ship survey has not only to consider time but space, i.e. port or dry shipyard, also. For merchant ships sailing between ports over the world, it will be called back to the shipyard for conducting ship survey once time and place are decided. This project will explore the contents of ship classification, survey system and certification management in detail. The survey items, constraints in conducting period for surveys and the selection of scheduling shipyards are also investigated. However, the difference characteristics of various shipping industrials makes complex for this issue, this project will focus on the time charter practice of tramp shipping services only. In this field, the date of conducting ship survey is controlled by the owner, but this arrangement will influence charterer’s operation. Normally, the charterer also considers whether the target ships will meet the surveys or not in the chartering period. It is expected to be avoided as possible from the charterer’s part. In the long-run contract, the charterer has to follow the arrangement from the owner. This project will take the routine surveys and dry docking into consideration for scheduling to the whole fleet. In terms of mathematical programming models, this project will provide the promising strategy for ship owners. It is hope that the results of this research can reduce the burden of managers in ship management and avoid the occasion of ship un-seaworthiness.
