Applicability Analysis of Lifting Operation for Large Derrick Barge under Mooring Based on MOSES
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.
