摘要
为降低大型锚泊定位起重船在不同水深区域吊装作业的安全风险,以 7 000t起重船为例,采用数值模拟方法,在MOSES软件中建立起重船、吊物和系泊系统耦合分析模型,对系泊下大型起重船吊装作业工况进行模拟,结果表明,系泊吊装作业受浪向、波高、波周期、锚缆预张力和作业水深变化的影响,在实际操作中,根据作业水深采取相应的船位和预张力,可以有效地改善大型起重船系泊吊装作业的适用性.
Abstract
In order to reduce the safety risks during the lifting operation of mooring derrick barge,with numerical simulation methods,a coupled analysis model including 7 000 t derrick barge,lifting object and mooring system was established in MOSES to simulate the lifting operation of mooring derrick barge.The results indicated that the lifting operations are influenced by chan-ges in wave direction,wave height,wave period,mooring line pre-tension,and operating water depth.In practical operations,a-dopting corresponding barge arrangement and pre-tension according to the operating water depth can effectively improve the appli-cability for lifting operation of mooring derrick barge.
