 ABSTRACT

Offshore gravity platform has been proved to be an effective way to exploit marginal oil fields since its first application. In offshore gravity platforms, heat preservation performance of submarine oil caisson is the key factor determining whether the oil will solidify or remain liquid which is easy to extract. In order to provide technical support for submarine oil storage in offshore gravity platform, the heat preservation performance of the submarine concrete oil caisson in gravity platform is investigated through experiment in laboratory and numerical simulation by ANSYS software. Obtained results from experiment and finite element simulation show that there is great consistency between them. It was proved that FEM model built in this paper is feasible and effective to simulate the temperature field of the oil caisson. It is demonstrated from experimental and numerical results that heat preservation performance of the submarine concrete oil caisson in gravity platform is effective and can meet the requirements of submarine oil storage generally
