辽东湾某平台位于辽东湾海域,距海岸最近距离15km.由于特殊气候及海域环境特点,辽东湾某平台所在海域每年冬季都会形成大量的海冰.该平台自2009年冬投产以后,由于平台特殊的结构特点,在连续几个年度冬季现场的冰激振动监测中,平台都发生较强的冰激振动,强烈的冰激振动给平台主结构及上部设施的安全带来严重威胁.根据现场监测及观察结果,针对辽东湾某平台结构特点,对平台冰激振动成因进行分析,并提出应对措施及建议.
Liaodong Bay a platform located in the Liaodong Bay waters, 15km away from the coast .Because of special climate and marine environment characteristics, a large number of sea ice is formed every winter in a certain platform of the Liaodong Bay. Since the platform was put into operation in the winter of 2009, due to the special platform In the continuous monitoring of ice-induced vibrations in winter, the ice-cooled vibrations of the platform are intense, and the intense ice-induced vibration poses a serious threat to the safety of the main structure and the upper part of the platform. According to the on-site monitoring According to the structural characteristics of a platform in Liaodong Bay, the cause of ice-induced vibration is analyzed and the countermeasures and suggestions are put forward.
