Description

Offshore platform prying block with waste liquid collecting tank

Technical Field

The utility model relates to the technical field of ocean platform skid blocks, in particular to an offshore platform skid block with a waste liquid collecting tank.

Background

The equipment on the offshore oil and gas production device is integrated into the equipment skid to operate on the ocean level. The sea weather is complex and changeable, severe weather such as strong wind and heavy rain is frequent, and most of equipment on equipment prying blocks in the marine environment is arranged in an open air environment. The equipment on the skid blocks is more prone to ageing leakage than inland equipment affected by severe weather on the sea, therefore, skid block edge baffles are welded at the bottom of an offshore skid block platform, when pipelines or equipment on the skid blocks are leaked accidentally, the leaked liquid can be blocked by the edge baffles, the leakage range of the leaked liquid is limited inside the skid blocks, and the liquid leaked by the equipment or pipelines inside the skid blocks is prevented from flowing onto a deck or causing marine pollution in the sea.

However, in the practical application of the edge baffle of the prying block, after the edge baffle of the prying block is arranged, because of the enclosing of the edge baffle, the accumulated liquid in the prying block is difficult to be completely discharged, the seawater in the accumulated liquid in the prying block forms accumulated salt on the prying block after being evaporated, and long-term accumulated salt accumulated water in the prying block causes accelerated corrosion of the equipment structure in the prying block. Meanwhile, when the liquid accumulation in the skid blocks is too much, the liquid accumulation in the skid blocks can overflow onto a deck or into the ocean, so that ocean pollution is caused.

Disclosure of Invention
