Ocean platform pile shoe

Abstract

The invention discloses an ocean platform pile shoe, and belongs to the field of lifting platforms. The pile shoe comprises a pile shoe body, a first ring-shaped sleeve, a ring-shaped cover plate, a rotating separation plate, a screw rod and a lift cylinder. During the pitching of a pile, the lift cylinder controls the screw rod to move, and the rotating separation plate rotates to separate a first through hole from a second through hole, so that sediment does not enter the pile shoe; during the pulling of the pile, the lift cylinder controls the screw rod to move, the rotating separation plate rotates to communicate the first through hole with the second through hole, the pile leg is pulled out from the pile shoe, and the resistance, caused by the sediment, to the pile shoe is greatly decreased as the first through hole and the second through hole are communicated, so that the pile leg can be pulled out more easily without setting pile washing equipment and then the expense is saved.

Description

technical field [0001] The invention relates to the field of lifting platforms, in particular to a spud shoe of an offshore platform. Background technique [0002] An offshore platform is a structure that provides production and living facilities for activities such as drilling, oil production, transportation, observation, navigation, and construction at sea. It is mainly composed of a platform part and a supporting part. The supporting part of the offshore platform mainly includes a spud leg and a spud shoe, and the spud shoe is fixed at the bottom end of the spud leg. The spud cans are generally inserted into the sediment on the seabed to bear the pressure of the entire offshore platform. [0003] Since the spud cans are subjected to relatively large pressure for a long time and sediment is deposited for a long time, it is difficult to pull the spud cans out of the mud and sand when the offshore platform needs to move. [0004] At present, in order to facilitate the extr...

AI Technical Summary

Problems solved by technology

[0003] Because the spud cans have been subjected to high pressure for a long time and the sediment has been deposited for a long time, it is difficult to pull the spud cans out of the sand when the offshore platform needs to be moved.

[0004] At present, in order to facilitate the extraction of the spud boots from the sand, corresponding pile flushing equipment is often installed to wash away the sand around the spud boots by using water flow or air flow. This method not only increases the time for pulling out the piles but also increases the The cost of purchasing related equipment
