渤海某新建升压站平台的抗冰性能分析

Analysis of the Structural Ice-resistant Performance for the Booster Station Platform in the Bohai Sea

为了明确海上升压站平台设计中抗冰设计的合理性,以渤海某新建升压站平台为例,采用有限元数值模拟方法分析典型冰况下升压站平台的抗冰性能,与渤海典型的油气平台对比表明,动冰力下,结构的振动不明显,在极值静冰下结构具有很大的静力安全储备;新设计的升压站平台具有较好的抗冰性能。

In order to make clear the ice-resistant performance and the rationality of the ice-resist design for the offshore boost station platform. A new boost station platform in Bohai is taken as an example. Its ice resistance performance under typical ice conditions is analyzed by FEM,and compared with the typical oil and gas platforms in Bohai. The results showed that the structure of the new designed boost station platform has a lot of static safety reserve under the extreme ice condition,and the structural vibration is not obvious under the dynamic ice loads. So the new designed booster station platform has good ice-resistant performance.
