【 摘 要 】

Some of the most frequent damages in the ship-mounted machinery occur in the propeller shaft system, and the most frequent damage is due to the exothermic accident occurs in the after stern tube bearing (STB). Recently, engine power and shaft diameter of very large crude-oil carriers (VLCCs) tend to increase whereas the distance between forward and after STB becomes shorter. In this study, the applicability of new shaft system for VLCCs adopting single STB system was investigated. The study results show that single STB system is quite possible by applying proper shaft arrangement and partial slope at the white metal. Also, a considerable economic effect is expected by simplifying related shaft system.
