双月池对某援潜救生船运动性能及波面升高的影响

介绍某援潜救生船配设双月池的船型特点,规划双月池和不带月池2种方案来评估双月池开口对援潜救生船船体运动性能的影响。采用三维势流理论对2个方案的运动性能进行计算,得到船体运动响应函数,对船舶运动性能进行短期预报,研究总结双月池效应对援潜救生船运动的影响规律。对比双月池内水面和舷外波面升高的情况,比较两个位置处波面升高的差异性,总结双月池波面升高对潜水钟收放的影响。

Influence of Dual Moon Pool on Motions Performance and Wave Elevation of a Rescue and Saturation Diving Support Vessel

The character of rescue support vessel (RSV) which is with dual moon pool in the middle of the hull is introduced. To study the effect of dual moon pool to motion of the RSV, 3D potential theory is used to calculate the motion RAO of RSV with dual moon pool and without moon pool. The hull motion response function of the RSV is gained. The short-term prediction for the RSV motion performance can be done. The influencing law of dual moon pool on the motion of RSV is studied and summarized. The wave elevation conditions of RSV in moon pool and outboard is compared. The difference of the wave elevation at the two positions is compared. It is evaluated that the influence of the wave elevation in the dual moon pool on the retractable system of the diving bell.
