A drilling ship moon pool stabilization wave-absorbing wall

Abstract

The invention relates to the technical field of ships, in particular to a drilling ship moon pool stabilization wave-absorbing wall which is provided with long kidney-shaped circular wave-absorbing holes in the stabilization wave-absorbing wall around a moon pool, and waves are divided by the stabilization wave-absorbing wall; the periphery of the stabilization wave-absorbing wall is further provided with a watertight enclosure wall and wave-absorbing partition plates; the wave-absorbing holes are communicated with the watertight enclosure wall, and sea waves flow back and forth among the watertight enclosure wall, the wave-absorbing partition plates and the stabilization wave-absorbing wall. The drilling ship stabilization wave-absorbing wall has the advantages that 1, the ship operationcomfort level can be improved by the ship stabilization wave-absorbing wall; 2, the ship stabilization wave-absorbing wall can reduce the influence of sea waves on the normal operation of ship equipment; and 3, the design and construction cost is lower; 4, the structure is simple, production and installation are convenient, the shipbuilding efficiency is improved, and the shipbuilding period is shortened; and 5, the maintenance in ship operation is easy.

Description

technical field [0001] The invention relates to the field of ships, in particular to a moon pool anti-rolling wall for a drilling ship. Background technique [0002] When a drilling ship is drilling in the ocean, the requirements for the amount of shaking of the ship and the height of seawater waves in the moon pool are extremely strict; when the height of sea water waves in the moon pool is high, the drilling pipe cannot reach the designated wellbore in terms of accuracy. . [0003] Usually, when the sea wave height is high, the drilling ship fills the ballast tanks with seawater ballast to make the ship reach full load draft, which can reduce the ship's shaking to a certain extent, but the effect of reducing the shaking is not good. Obviously, and did not reduce the wave height in the moon pool. [0004] In addition, some drilling ships choose to conduct drilling operations when the sea conditions are good, which not only results in extremely low efficiency of drilling o...

Problems solved by technology

[0003] Usually, when the sea wave height is high, the drilling ship fills the ballast tanks with seawater ballast to make the ship reach full load draft, which can reduce the ship's shaking to a certain extent, but the effect of reducing the shaking is not good. Obvious, and did not reduce the wave height in the moon pool

[0004] In addition, some drilling ships choose to carry out drilling operations when the sea conditions are good, so not only the efficiency of drilling operations is extremely low, but also the waiting costs for drilling operations are high
