12500载重吨重吊多用途船破损稳性研究

在保证大开口货舱功能需求的前提下,研究12 500载重吨重吊多用途船的破损稳性,使其满足分舱指数要求。对货舱数量、边舱数量、边舱宽度、水密二甲板分隔高度、双层底高度、压载水舱型式等各因素进行定性分析,获得各因素对该船破损稳性的影响趋势,指导该船的破损稳性设计。同时也评估了机舱区域船底破损,使其满足公约的要求。最终得出同时兼顾船舶功能和破损安全的设计,对类似的万吨级重吊多用途船的开发具有借鉴意义。

On damage stability of 12 500 dwt heavy lift multi-purpose vessel

The damage stability of a 12 500 dwt heavy lift multi-purpose vessel is studied to meet the requirement of the subdivision index with the functional assurance for the large hatch cargo hold. The qualitative analyses of the various factors, such as cargo hold quantity, side tank quantity, side tank width, the height of the watertight tween deck, double bottom height and ballast tank type are performed to obtain their influence on the damage stability to guide the design of the ship. The damage to the bottom of the engine room is also assessed to meet the requirements of the convention. Finally, the produced excellent ship design with the consideration of both the ship function and the damage safety can be refered for the development of similar 10 000 dwt class heavy lift multi-purpose vessels.
