Anti-collision device for stand column oil tank in semi-submersible production platform

Abstract

The invention discloses an anti-collision device for a stand column oil tank in a semi-submersible production platform. The anti-collision device comprises an oil tank wall, an outer wall and a plurality of horizontal plates; the oil tank wall and the outer wall are sequentially arranged on the periphery of the oil tank from inside to outside, and the oil tank wall and the outer wall are connectedthrough the horizontal plate. The anti-collision device is small in occupied space, steel is saved, and oil substances stored in the multi-stand-column column column-stabilized platform stand columncan be stably protected in an anti-collision mode.

Description

technical field

[0001] The invention relates to an anti-collision device for a column oil tank in a semi-submersible production platform, and belongs to the field of structural design of floating platforms in marine engineering. Background technique

[0002] As the development of offshore oil and gas advances to deeper and farther seas, it will face the problem of how to dispose of the oil products produced in the production of gas fields. Due to the long offshore distance, it is not economical to build new pipelines for such oil products alone, or the surrounding pipeline network is not good enough. If it is suitable for oil transportation, it is necessary to store the produced oil products on the platform. In the production of deep-water gas fields, a column-stabilized platform in the form of multiple columns is a better choice, such as a semi-submersible platform. However, when oil products are stored on a semi-submersible platform, it is required to meet safety requireme...
