海洋工程船U型减摇水舱设计

Design of U-shaped anti-rolling tank for offshore construction vessels

采用经验公式及设计经验相结合的方式研究U型减摇水舱在初期阶段设计的过程。首先对U型减摇水舱的工作机理、减摇水舱参数、固有周期进行分析,研究U型被动可控式减摇水舱的特点,然后对其适用船型、布置位置、设计约束条件、效果评价等方面进行研究,提出一种对被动可控式减摇水舱的设计流程,最后举例设计并验证目标船舶的减摇水舱设计。

This paper investigates the initial design stage of the U-shaped anti-rolling tank by the empirical formula combined with the design experience. Firstly, the operation principle, anti-rolling parameter and natural period of the U-shaped anti-rolling tank are analyzed. Then, the suitable hull form, arrangement location, design constraint and effect evaluation are studied for the design process for a passively controlled anti-rolling tank.Finally, an anti-rolling tank of the target ship is designed for the validation.
