The invention provides an underwater emergency oil control device, which includes an anti-settling plate, a long skirt plate, a mud entry plate, a main shell steel plate, an inclined shell steel plate, a top shell steel plate and a steel structure frame, a main shell steel plate, an inclined shell steel plate and a top shell The steel plate is installed on the steel structure frame and constitutes a room-shaped space with an open bottom and a closed upper end. The dust-proof board is horizontally arranged on the bottom layer of the steel structure frame, and the long skirt board is vertically arranged under the end of the dust-proof board. There are four and Set at the lower end of the steel structure frame, each set of inclined shell steel plates is provided with four sets of drag reducing holes, each set of drag reducing holes has two columns, and each set of drag reducing holes is provided with a drag reducing structure. The present invention can achieve: when the underwater emergency oil control device completely covers the leakage point, the sealing slide plate 102 is moved to the clamping end through the ROV operating handle 101 to close the drag reduction hole, and the leaked 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.
