Problems solved by technology

[0005] In view of this, the present invention aims to provide a semi-submersible platform oil storage tank, which can meet the oil and gas circulation of condensate oil, and solve the problem of complex and cumbersome external transportation equipment related to condensate oil; A semi-submersible platform with an inert gas pipeline system that integrates the functions of inert gas venting, ventilation, storage oil overflow and diversion, etc., and can avoid condensate oil tanks caused by excessively high vent holes on the top of the inert gas pipeline. The design pressure head is too large in the structural design to ensure that the oil storage in the column of the semi-submersible platform is safe, reliable, and economical and reasonable

Embodiment Construction

[0024] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to understand the purpose, features and advantages of the present invention more clearly. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but merely to illustrate the essential spirit of the technical solution of the present invention.

[0025] The oil storage tank designed in the present invention is innovatively designed on the basis of the traditional sub-cabin design of the semi-submersible platform to meet the needs of oil storage related functions and solve the need for multiple sets of condensate related export equipment due to multiple cabins The complex and tedious problems of equipment, and make the structure of the oil storage tank meet the strength design requirements, can solve the structural design problems such as stress concentration an...

Abstract

The invention relates to a semi-submersible platform oil storage cabin and a semi-submersible platform. The oil storage cabin is arranged in a stand column of the semi-submersible platform, the interior of the oil storage cabin comprises a continuous type or non-continuous type cabin wall, and the cabin wall divides the oil storage cabin in the stand column into a plurality of spaces which communicate with one another in the horizontal direction. The semi-submersible platform comprises a set of stand columns, and each stand column comprises the semi-submersible platform oil storage cabin. According to the semi-submersible platform oil storage cabin and the semi-submersible platform, the semi-submersible platform oil storage cabin with an enough strength supporting structure can be provided, the oil and gas circulation of condensate oil can be met, and the problem that condensate oil related external conveying equipment is complex and tedious is solved; and furthermore, an inert gas pipeline system integrates the functions of inert gas venting, air permeability, storage oil overflow and diversion and the like, and the problem that a design pressure head is too large in the structural design of a condensate oil cabin due to the fact that air holes formed in the top of an inert gas pipeline are too high is solved.

Description

Technical field [0001] The invention relates to the technical field of marine engineering oil storage platforms, in particular to a semi-submersible platform oil storage tank and a semi-submersible platform. Background technique [0002] In the process of offshore oil and gas field development, as the distance and water depth of the sea area explored increase, the investment in oil and gas field development is also increasing. Reducing oil and gas field development engineering facilities is an effective way to reduce costs, but the basic functions must be retained. For example, for some gas field development, although the main product is natural gas, condensate will be produced at the same time. If the gas field is close, it can be transported by the corresponding pipeline, but for the deep water gas field offshore, whether it is a separate pipeline transportation Whether condensate is transported together with natural gas, it will encounter technical problems and increase invest...
