Underwater robot platform of semisubmersible drilling platform

Abstract

The invention relates to an underwater robot platform of a semisubmersible drilling platform, which is characterized in that: the underwater robot platform comprises two bases arranged at a position of a left side and a position of a right side of a main deck, one part of the base is fixed on the main deck, while the other part extends out of the main deck; a lowering window is arranged in the middle of an extension end of the base, a support is arranged on the upper part of the extension end of the base; the support is divided into three layers, and two guide rope winches, a umbilical winch and a sliding seat cushion are arranged on the support in return from top to down; a fixing end of the base is provided with a wave compensation winch and a hydraulic power station; the two guide rope winches are connected with a weight block through a steel wire rope, the umbilical winch is connected with the underwater robot through a cable, and the wave compensation winch rounds pulleys fixed on the support and the underwater robot in turn through the cable; and the sliding seat cushion is arranged on the upper part of the lowering window. The underwater robot platform not only enables the underwater robot to be lowered smoothly in bade environment, but also has wider selectivity for the underwater robot.

Description

technical field [0001] The invention relates to a robot fixed platform, in particular to an underwater robot platform of a semi-submersible drilling platform. Background technique [0002] At present, most drilling platforms do not have a dedicated underwater robot platform, but generally adopt the operation method of lowering the underwater robot from the moon pool, the port side or the starboard side of the drilling platform, and there is no guiding device for the underwater robot, which is This method of operation mainly has the following problems: 1. The lowering mode applicable to the underwater robot is relatively single, and generally only the underwater robot that the boom type can be lowered can be selected. 2. Since there is no guide frame for lowering the underwater robot, it cannot be applied to harsh sea conditions. 3. Since there is only one place where the underwater robot can be stored, when the wind direction becomes unfavorable to the lowering of the under...

Problems solved by technology

[0002] At present, most drilling platforms do not have a dedicated underwater robot platform, but generally adopt the operation method of lowering the underwater robot from the moon pool, the port side or the starboard side of the drilling platform, and there is no guiding device for the underwater robot. This method of operation mainly has the following problems: 1. The lowering mode applicable to the underwater robot is relatively single, and generally only the underwater robot that can be lowered by the boom type can be selected.

2. Since there is no guide frame for lowering the underwater robot, it cannot be applied to harsh sea conditions

3. Since there is only one place where the underwater robot can be stored, when the wind direction becomes unfavorable for the lowering of the underwater robot, it is easy for the underwater robot to touch the buoyancy tank.
