Finite element analysis of overall structural strength of multifunctional offshore platform
多功能海洋平台整体结构强度有限元分析

摘要

本文结合自升式生产储油平台引入水下储油概念，提出了一种可移动组装式水下储油平台概念，成为集钻、采、储、输于一体的边际油田多功能平台，适用开采水深200米左右的海上边际油田，以解决传统自升式生产储油装置储油量有限、成本高等问题。针对新型的可移动组装式新型海洋平台，利用有限元软件ANSYS对其进行整体结构强度分析，并对工况类型、载荷施加计算等问题进行相应说明。

Abstract

In this paper, the concept of underwater oil storage is introduced into the jack-up production and storage platform, and a concept of mobile assembled underwater oil storage platform is proposed. It becomes a multi-functional platform of marginal oil field integrating drilling, production, storage and transport, which is suitable for the marginal oil field with a depth of about 200 meters, so as to solve the problems of limited oil storage and high cost of traditional jack-up production and storage device. Aiming at the new movable assembly type offshore platform, the strength analysis of its whole structure is carried out by using the finite element software ANSYS, and the problems of working condition type and load calculation are explained accordingly.
