Abstract

The invention provides an underwater emergency oil control device. The device comprises an anti-settling plate, a long apron plate, mud inlet plates, a main shell steel plate, oblique shell steel plates, a top shell steel plate and a steel structural frame, wherein the main shell steel plate, the oblique shell steel plates and the top shell steel plate are mounted on the steel structure frame andform a room-shaped space with the bottom end opened and the upper end closed, a dustproof plate is horizontally arranged at the lowermost layer of the steel structure frame, the long apron plate is vertically arranged below the end part of the dustproof plate, the four mud inlet plates are arranged at the lower end of the steel structure frame, four groups of drag reduction holes are formed in each oblique shell steel plate, each group of drag reduction holes are arranged in two columns, and a drag reduction structure is arranged on each group of drag reduction holes. When the underwater emergency oil control device completely covers leakage points, a sealing slide plate 102 is moved to the clamping end through an ROV operating handle 101 to realize closing of the drag reduction holes, andleaked crude oil is collected in the underwater emergency oil control device.

Description

technical field [0001] The invention relates to an underwater emergency oil control device, which belongs to the field of offshore oil engineering. Background technique [0002] With the shortage of oil resources on land, people's attention has gradually focused on the exploitation of offshore oil. With the continuous improvement of offshore oil engineering technology, the number of offshore oil exploration platforms has increased sharply, which also puts forward more requirements for underwater emergency oil control transfer devices. High requirements, the working water depth is 500m, the pressure is 5MPa, and it is suitable for the seabed cohesive soil layer or sandy soil layer with a shear strength of 5kPa~30kPa. This makes the mechanical structure of the oil control transfer system more complex, requiring higher stability, faster response speed and overall performance improvement, resulting in more complicated installation of the oil control device.
