摘要
辽东湾某平台位于辽东湾海域,该海域每年冬季都会形成大量的海冰,海冰给平台的作业生产及船舶运输带来严重安全威胁.由于辽东湾某平台结构特殊,海冰不仅使平台发生较强的冰激振动,同时海冰也在平台底部形成堆积,给平台冬季的安全运行带来一定的安全隐患.基于多年冬季现场监测,针对平台底部冰堆成因及冰阻塞对平台安全影响进行分析,并给出应对措施及建议.
The platform is in the Bohai sea area,about 6 km distance from the main platform in the west.This area covers with large number of sea ice during the winter time every year.Sea ice has caused a serious security threat to the production and shipping of crude oil in the platform.Because of the special structure of platform,sea ice not only causes the vibration of the platform,but also form ice accumulation at the bottom of the platform,bring certain potential security problems to the safety of the platform in winter.In this paper,based on many years of field monitoring,we will analysis the formation and the impact of the ice accumulation to the platform,and give some countermeasures and suggestions.
