摘要
针对惠州25-8DPP动力定位浮托组块的退船阶段进行模型试验,分析浮托安装船在不同的海洋环境下的退船过程,测量并分析浮托驳船的运动轨迹、推进器功率消耗以及护舷靠垫力,得到退船阶段的特性与规律。结果表明,180°与0°的退船工况具有较好的退船特性,并且在退船过程结束时,由于缺少靠垫力的作用以及受到风浪流环境力的作用,浮托驳船受到艏摇力矩的影响,容易出现甩尾现象。
Float-over installation executed by dynamic position system has more advantages in reducing costs than traditional mooring system.This research focused on the undocking operation in Huizhou 25-8 DPP float-over installation and completed model test to obtain information of track,consuming power and collision between vessel and fenders which were helpful to study the properties and laws in undocking case.Compared to other incident angles,undocking operation performs better in 180° and 0°.At the end of undocking operation,float-over barge shows spin phenomenon.The phenominon involves a variety of technical reasons.The main reason is bow wave moment caused by environment force and the lost of cushion force.This work can provide advice to build time domain simulation of float-over executed by dynamic position system and practical instruction for engineer to conduct practice engineer.
