Problems solved by technology

[0002] The original seawater supply method of the jack-up drilling platform adopts the centralized supply of seawater towers. Three submersible pumps are placed in the seawater towers. When berthed by ships and in severe winter seasons, due to strong winds and sea ice floes, ships may accidentally collide with seawater towers and ice floes. The major hidden danger of the seawater tower is that it is easy to cause the seawater tower to be subjected to excessive force, break into the sea or be damaged by bending, and the platform loses the seawater supply, thus affecting the normal drilling operation of the platform

Abstract

The invention discloses a seawater tower for a self-elevating drilling platform and the self-elevating drilling platform. The platform comprises a pile leg and a pile shoe. The seawater tower comprises a sliding rail, a lifting pipe, an immersible pump and an auxiliary seawater supply device. The sliding rail is arranged on a chord pipe of the pile leg. A plugging device is arranged at the bottom of the sliding rail, and the sliding rail is provided with a pin hole. The auxiliary seawater supply device is arranged on the top of the lifting pipe. The immersible pump is provided with a protection pipe. The lifting pipe is provided with a sliding locking device, and the immersible pump is provided with a sliding locking device. The sliding locking devices are used for being matched with the sliding rail to achieve sliding or locking of the immersible pump and the lifting pipe. The plugging device is used for protecting the pile shoe against damage when the immersible pump disengages. The protection pipe is used for preventing the immersible pump from being damaged by the external environment. The immersible pump, the lifting pipe and the auxiliary seawater supply device are used for jointly achieving seawater supply of the platform. The platform further comprises the seawater tower. The capability of resisting the severe weather through the seawater tower is improved, seawater supply continuity of the platform in the severe weather is ensured, and accordingly normal drilling work of the platform is not affected.

Description

technical field [0001] The invention relates to a seawater tower and a drilling platform, in particular to a seawater tower and a jacking-up drilling platform used for a jack-up drilling platform. Background technique [0002] The original seawater supply method of the jack-up drilling platform adopts the centralized supply of seawater towers. Three submersible pumps are placed in the seawater towers. When berthed by ships and in severe winter seasons, due to strong winds and sea ice floes, ships may accidentally collide with seawater towers and ice floes. The major hidden danger of the seawater tower is that it is easy to cause the seawater tower to be subjected to excessive force, break into the sea or be damaged by bending, and the platform loses the seawater supply, thus affecting the normal drilling operation of the platform. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a seawater tower for a jack-up dril...
