摘要
海洋工程船的减摇是适应其服务的海洋与气象环境的实际需要,关系到海工船工作效率、舒适性和安全性。阐述了横摇的减摇基本原理、减摇的运动微分方程式并编制了适用于平面纯被动减摇水舱的计算程序;分析了自摇周期的经验公式的适用性,以及不同减摇水舱尺寸、不同介质对减摇效果的影响;通过对PSV(海洋平台供应船)和AHTS船(多功能海洋锚作拖船)的减摇计算与分析,展望了纯平面减摇水舱实际使用的前景。
Ocean engmeenng vessels have the actual need tor motion stabization in order to adapt to different ocean and weather environment in service, which is related to their working efficiency, comfort level and safety. This study elaborates the basic principle of anti-rolling, introduces the anti-rolling motion differential equation, and programs a computer code suitable for planar pure passive anti-rolling tanks, to analyze the applicability of empirical formula for estimating self rolling period and the influence of various anti-rolling tank dimensions and media on the anti-rolling effect. Based on the anti-rolling computation and analysis of a Platform Supply Vessel （PSV） and an Anchor Handling Tug Supply vessel （AHTS）, some outlooks for the practical application of planar pure passive anti-rolling tanks are given.
