摘　　要：为提高油田守护船上船员生活的舒适性和安全性,提升船舶的作业效率,要求船舶具有较好的耐波性。以某油田守护船为例,通过为其设计矩形减摇水舱,减小船舶的横摇幅值,适当增大横摇周期,减少甲板上浪,提升船舶的耐波性。阐述矩形减摇水舱的力学模型和设计原理,并根据设计原理给出该型船舶的可自动调节液面矩形减摇水舱设计方案;通过减摇水舱模型试验和船模水池试验,论证减摇水舱对提升船舶耐波性的真实有效性。通过在船舶试航过程中对减摇水舱系统数据进行收集,证明该型船舶的可自动调节液面矩形减摇水舱设计是成功的。To improve the comfort and safety of the crew and to increase ship operation efficiency, a rectangular anti-rolling tank is designed for the Anchor Handling Tug Supply (AHTS) vessel to reduce roll amplitude, increase roll period and decrease green water on deck so as to improve the sea-keeping performance of the ship. This paper elaborates the mechanical model and design principles of the rectangular anti-rolling tank, and proposes a design that can adjust the tank water level automatically. The anti-rolling tank model test and the ship model test in the basin have validated the effectiveness of the anti-rolling tank in improving the ship's seakeeping performance. Data collection for the anti-rolling system during sea trial also confirms that the proposed design with automatic water level adjustment is successful.
