Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The large-scale oil storage device that the present invention designs and is applicable to shallow sea seabed cuboid form is as follows:

[0035] 1. Target working environment: 40 meters deep seabed environment.

[0036] 2. Type and type of oil storage device: double-layer (divided into inner and outer plates), bottomed, cuboid steel structure.

[0037] Dimensions of the oil storage device: length × width × height = 111.4m × 27.4m × 11.4m, using a longitudinal frame structure, the inner and outer plates of the device and welded steel on the closed watertight bulkhead, the inner and outer plates The board spacing is 1.7m. There are three cabins in the device (the cabins can be 2, four or more), and the three cabins are arranged in a line along the length direction. The cross section of each cabin is rectangular. Each cabin is ...

Abstract

The invention belongs to the technical field of ocean engineering, in particular to a large-scale oil storage unit applicable to a shallow sea area. The oil storage unit is a cuboid two-layer steel plate steel structure and comprises a deck, a bottom board, a shipboard and a naval ship which are all longitudinal skeleton-type two-layer steel plate components; a closed watertight bulkhead and a man-hole bulkhead are arranged between the inner layer plate and the outer layer plate; the steel stiffeners are welded on the inner layer plate, the outer layer plate and the closed watertight bulkhead; the inner layer plate has a watertight welding steel plate structure; the steel structure is internally provided with two or more cabins which are arranged in a horizontal way; the cabins are communicated one another and separated by struts; and an oil removal system of the steel structure comprises an oil film, an oil separation plate and an oil separation interlayer. The oil storage unit can meet the oil storage requirement of short time of a marine moving platform, and overcomes the sea pollution problem caused by produced crude oil.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to a large-scale oil storage device in the form of a cuboid in shallow sea area, which is suitable for storing crude oil in the development of marginal oil fields. Background technique [0002] Oil and natural gas occupy a very important position in the energy structure. After long-term and large-scale exploitation of onshore oil and gas resources, worldwide oil and gas exploration and development have moved to the vast ocean, and gradually formed a new field of energy industry with high investment, high risk, and high-tech intensive. With the development of offshore oil development from offshore to far sea and deep sea, the storage of crude oil has also developed from onshore oil storage to offshore oil storage. Offshore oil storage can be divided into three main methods: above-water oil storage, surface oil storage and underwater oil storage. [0003] Oil ...
