Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water cutting, in particular to a high-efficiency high-pressure water cutting device for offshore platform cutting. BACKGROUND

[0002] According to the abandonment requirements of offshore oil platforms and the requirements of offshore environmental protection, a large number of fixed jacket platforms for oil production on the sea need to be dismantled. The dismantling of offshore oil platforms can be specifically divided into the dismantling of wellheads, the dismantling of process equipment and mechanical equipment, the dismantling of upper blocks, and the dismantling of jacket platforms. The dismantling of jacket platforms is the longest and most costly project in the entire dismantling process. Underwater conduit dismantling generally involves a number of cutting operations, such as focused explosion cutting, underwater electric oxygen cutting, mechanical cutting, diamond wire saw cutting, and abrasive jet cutting. Regardless of the dismantling scheme adopted, a large number of underwater cutting operations are involved. When cutting operations are performed on offshore oil and gas conduits, cutting techniques such as electric oxygen and focused explosion are often selected, which may potentially cause explosions. Offshore platforms are generally built with columns on the lower side and platform surfaces on the upper side. When dismantling offshore platforms, water cutting is often used. Water cutting generally requires manual platform construction or divers to enter the sea surface to control the equipment for cutting. However, due to the large number of columns on the lower side of the platform, a platform needs to be constructed for each cutting operation, which results in low cutting efficiency. In addition, since the columns are deep into the seabed, divers need to enter the seabed to complete the cutting operation, which results in low efficiency of the equipment during operation and seriously affects the work progress of the equipment, and poses a certain risk to the workers.
