Study on the Design of Planar Pure Passive Anti-rolling Tank

Ocean engineering vessels have the actual need for motion stabilization 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.
