渤海新型抗冰导管架平台研究

根据渤海海洋平台长期现场监测结果,对渤海海域冰与导管架平台相互作用问题进行了系统研究,指出冰激结构振动是目前渤海冰区导管架平台的主要危害。应用冰激导管架平台冰激振动及动冰力研究成果,对新型抗冰振平台设计方案进行了分析。对适用于导管架平台的冰激振动控制装置进行了理论分析与实验研究。在新建JZ20-2NW平台的设计建造中应用了上述研究成果。新建平台现场监测结果分析表明,新型平台比以往平台具有更好的抗冰振性能。

Study of a new ice resistant jacket platform in Bohai Sea

The interaction of sea ice and jacket platform was studied systematically on basis of field monitoring results of platforms in Bohai Sea and it was found that ice induced vibration of the structure is the main problem to the jacket platform in Bohai icing waters.The study results of dynamic ice load and ice induced vibration have been used to analyze the program for designing a new ice resistance platform.The theory analysis and experimental study were performed to the ice induced vibration mitigation method for jacket platform.The study results mentioned above were adopted in the design and construction of JZ20-2NW platform.The field monitoring result of the platform shows that the new platform has a better ice resistant capability than other platforms in the same oil field.
