Problems solved by technology

[0002] The moon pool mainly exists in the drilling ship. When the drilling ship is working, the water in the moon pool sloshes, causing a serious threat to the side wall of the moon pool and even the entire hull structure.
When the actual drilling ship works in the ocean, due to the effect of wind and waves, the ocean environment is harsh, and the moon pool existing in the ocean structure will pose a great threat to the stability and safety of the entire structure
At the same time, in actual work, the water in the moon pool mainly sloshes along the long side, so the impact on the short side is greater
At the same time, during the working process of marine structures, the sloshing of water in the moon pool and the impact on structures will cause structures such as drilling ships to slosh, and the sloshing of structures will cause discomfort to construction workers working on structures. Reactions such as seasickness

Embodiment

[0026] like figure 1 As shown, the present application proposes a new type of moon pool anti-rolling and wave-eliminating wall, which is installed inside the marine structure, especially in the drilling ship, on the short side wall 1 of the drilling ship moon pool. The device includes a vertical anti-rolling wave-absorbing wall vertically arranged in front of the short-side side wall 1 of the moon pool at a certain distance, and a horizontally-set horizontal A plurality of neatly arranged holes are respectively arranged on the anti-rolling and wave-removing wall 6 , the vertical anti-rolling and wave-removing wall and the horizontal anti-rolling and wave-removing wall 6 .

[0027] like figure 2 , 3 As shown, the anti-rolling and wave-eliminating walls are symmetrically arranged on the short side walls 1 of the moon pool on both sides, and the vertical anti-rolling and wave-eliminating walls are respectively arranged on the short side walls 1 of each side of the moon pool at...

Abstract

The invention relates to a novel moon pool stabilization and wave absorbing wall which is arranged on the short side wall of a moon pool and comprises vertical stabilization and wave absorbing walls which are vertically arranged in front of the short side wall of the moon pool at certain intervals, and horizontal stabilization and wave absorbing walls which are horizontally arranged are arranged between the vertical stabilization and wave absorbing walls and the short side wall of the moon pool. A plurality of holes are respectively formed in the vertical stabilization and wave absorbing wallsand the horizontal stabilization and wave absorbing walls. Compared with the prior art, according to the design, moon pool resonance can be avoided more effectively, and a better wave absorbing and stabilizing effect is achieved; the two layers of vertically-arranged stabilization and wave absorbing walls can reduce slapping of transverse waves on a ship body to a greater extent, the three layersof horizontally-arranged stabilization and wave absorbing walls can slow down vertical movement of the moon pool, and finally the effects of stabilization and wave absorbing and ship body protectionare achieved.

Description

technical field [0001] The invention relates to a moon pool anti-rolling and wave-eliminating device, in particular to a novel moon-pool anti-rolling and wave-eliminating wall. Background technique [0002] The moon pool mainly exists in the drilling ship. When the drilling ship is working, the water sloshing in the moon pool will cause serious threats to the side wall of the moon pool and even the entire hull structure. When the actual drilling ship works in the ocean, due to the effect of wind and waves, the ocean environment is harsh, and the moon pool existing in the ocean structure will pose a great threat to the stability and safety of the entire structure. At the same time, during actual work, the water in the moon pool mainly sloshes along the long side, so the impact on the short side is greater. At the same time, during the working process of marine structures, the sloshing of water in the moon pool and the impact on structures will cause structures such as drilli...
