- 摘要:
- 合理地选择安全可靠且经济性好的锚固基础，是保障圆角倒棱台形浮式生产储卸油装置平台作业安全和边际油田开发效益的关键技术问题。针对IQFP平台拟作业的某浅海边际油田海域的海洋环境条件及海底土层地质特点，结合桩基础和吸力基础的总体结构与锚泊点载荷特征，从承载能力、施工技术、适用范围、利用率及经济性等多方面，详细对比了这两种基础形式对本工程的适用性，最终优选出吸力基础作为IQFP平台的锚固基础。研究成果可为浮式平台锚固基础的选型设计提供参考。
Selecting a safe, reliable, and cost-effective anchor foundation is a crucial technical issue in order to ensure the operational safety and marginal oilfield development benefits of the fillet inverted quadrangular frustum pyramid shaped FPSO (IQFP) platform. In light of the marine environmental conditions and geological characteristics of the seabed soil layers in some marginal oilfields in shallow sea areas where the IQFP platform was planned to operate, the adaptability of pile and suction foundations for the engineering case was evaluated in detail from multiple aspects, including bearing capacity, construction technology, application scope, utilization rate, and economy. This evaluation considered the overall structure and anchor load characteristics of the pile and suction foundations. The results indicate that the suction foundation is the optimal choice for the project example. The findings of this study can serve as a reference for the selection and design of anchor foundations for floating platforms.
