摘要
针对大型油船在现有码头停靠、改造时的空载系泊情况,采用物理模型试验方法,分析了处于改造作业过程中吃水较小、受风面积较大的30万t级油船的缆绳受力情况,研究了吹开风作用下以及风浪联合作用下波浪与风速对缆绳受力的影响,得出了原系泊方案最不利缆绳位置。针对风暴情况下船舶系缆布置方式存在的问题,提出了相应的优化方案,并开展相关试验研究。研究结果表明:优化方案可使各个缆绳受力更加均匀,避免某根缆绳受力较大的情况,试验结果可为相关设计提供一定的依据。
Aiming at the no-load mooring situation of large oil tankers during the reconstruction operation of the existing wharves,the method of physical model test was used to analyze the cable resistance of the 300,000-ton oil tanker with shallow draft and large wind area.The influence of wave and wind speed on the cable force under the action of blowing wind and the combined action of wind and wave was studied,and the most unfavorable position of the cable in the original mooring scheme was found.In view of the problems existing in the mooring arrangement during storm conditions,a corresponding optimization plan was put forward,and relevant experimental studies were carried out.The research shows that the optimized scheme can make the force of each cable more uniform and avoid the situation that a certain cable is subjected to a large force.The test results can provide a certain basis for the relevant design.
