摘要
渤海自立号采油平台是由大沉垫基础的自升式钻井平台改造而成。由于大沉垫式基础在渤海使用曾发生过多次滑移,该平台采用了导流基础结构刚性防滑桩。本文对防滑桩的设计制造、海上安装、起浮搬迁的全过程进行了实践经验的总结。
Zili production platform was converted from a jack - up drilling platform with large size mat foundation. Since several slip were resulted from the mat type foundation used in Bohai, the rigid slip prevention pile of diversion foundation structure was adopted by the platform. The process of design and fabrication, offshore installation and float/remove of slip prevention pile are summarized in this paper.
