Abstract

The invention relates to a protection device for an underwater oil and gas facility. The device comprises a protection main body covering the underwater oil and gas facility, wherein the protection main body is of a hollow housing structure and is manufactured through a glass fiber composite material; the upper side surface of the protection main body is provided with the hatch, and the hatch is provided with a hatch cover which can open and close the hatch; and two horizontal opposite sides of the protection main body are provided with openings for leading out pipelines of underwater oil andgas facility covered by the protection main body. According to the device, the protection main body is manufactured through the glass fiber composite material, so that the product structural design shape is diversified; the manufacturing cycle is short; a die is recyclable; the cost is low; the chemical corrosion is resistant; the mass is light; the strength is high; the design and manufacturing are flexible; the high and low temperature is resistant; and the hoisting and transporting are convenient. The device is capable of preventing the underwater oil and gas facility from being damaged bymatters falling from upper part and fishing tools.

Description

technical field [0001] The invention relates to the field of offshore oil development, in particular to a protection device for underwater oil and gas facilities. Background technique [0002] With the rapid development of domestic marine fishery fishing methods and offshore oil underwater facilities, the impact of fishing activities on underwater facilities has become more and more obvious. [0003] Fishing trawls are getting deeper and deeper, causing underwater facilities to be damaged by fishing nets and fishing gear, forcing oil fields to stop production and requiring a lot of money for repairs. [0004] At present, domestic underwater oil and gas production facilities all use steel structure protection devices. The structure is large in size, high in weight, difficult to design in shape, requires anodic anticorrosion, and high in cost. Therefore, it is impossible to carry out post-protection of underwater oil and gas facilities. Contents of the invention [0005] T...
