Description
Technical field
The present invention relates to ship domain, specially a kind of drill ship moon pool, which subtracts, shakes wave absorption wall.
Background technique
For drilling well ship in ocean when drillng operation, the seawater wave high request in the amount of rocking and moon pool to ship is extremely tight
Lattice；When seawater wave in moon pool is high larger, in precision, the drilling rod of drilling well can not be reached at specified wellbore.
In general, drill ship is when seawater wave is high larger by allowing ship to reach in each ballast tank filling seawater ballast of ship
Full-load draft, in this way can a degree of reduction vessel roll amount, but the effect for reducing the amount of rocking is not obvious, and is not had
The wave reduced in moon pool is high.
In addition, the selection of some drilling well ships carries out drillng operation when sea situation is preferable, the not only efficiency of drillng operation in this way
It is extremely low, and drillng operation delay cost is higher.
Summary of the invention
Present invention aims in view of the deficiencies of the prior art, and a kind of drill ship moon pool is provided subtracts and shake wave absorption wall to reach
To the requirement for meeting drillng operation under the conditions of severe sea condition, while specific lower cost and efficient drillng operation efficiency.
It is achieved through the following technical solutions above-mentioned purpose:
A kind of drill ship moon pool, which subtracts, shakes wave absorption wall comprising moon pool, the subtracting to shake of the moon pool surrounding are provided with long waist on wave absorption wall
Round wave absorption hole, wave, which is subtracted, shakes wave absorption wall point wave；Described subtract shakes wave absorption wall periphery and is additionally provided with watertight wall and wave absorption partition,
The wave absorption hole is connected with watertight wall, and wave is in watertight wall, wave absorption partition and subtracts to shake and flows back and forth between wave absorption wall.
It shakes wave absorption wall as subtracting to a kind of above-mentioned drill ship moon pool and further describes, platform is equipped with above moon pool edge
Plate is provided with round discharge orifice on the platform board, subtract shake the seawater free surface that is formed between wave absorption wall and watertight wall with
The height of seawater free surface in moon pool is the same, reduces wave heights by platform board.
It shakes wave absorption wall as subtracting to a kind of above-mentioned drill ship moon pool and further describes, watertight wall separates seawater and ship
Inner space.
It shakes wave absorption wall as subtracting to a kind of above-mentioned drill ship moon pool and further describes, the equidistant cloth in the discharge orifice
It sets.
The present invention has the advantages that
1. ship can be allowed to achieve the effect that wave absorption is shaken in certain subtracting under rather harsh sea situation, drill ship is allowed to meet drilling well work
Industry environment.
2. its structural shape is simple, design and manufacture are relatively easy to.
3. versatility is good, there is the drill ship of moon pool applicable.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-6, a kind of drill ship moon pool, which subtracts, shakes wave absorption wall comprising:
The subtracting to shake of moon pool surrounding is provided with long kidney ellipsoid wave absorption hole 3 on wave absorption wall 1；It is passed when wave is spread in moon pool to moon pool surrounding
Broadcast, the propagation of ocean waves collides subtract and shake wave absorption wall 1 after, wave, which is subtracted, to be shaken wave absorption wall 1 and divides wave；It shakes wave absorption wall due to subtracting and has been covered with wave absorption
Hole, big portion's wave travel to watertight wall 2 and wave absorption partition 4 by subtracting the wave absorption hole 3 shaken on wave absorption wall 1, i.e., most of wave
In watertight wall 2, wave absorption partition 4 and subtract to shake and carry out back propagation between wave absorption wall 1, wave is gradually reduced, and ship is made to have reached to subtract and shake
The effect of wave absorption.
It is provided with round discharge orifice 6 on platform board 5, subtracts the seawater free surface for shaking and being formed between wave absorption wall 1 and watertight wall 2
As the height of the seawater free surface in moon pool, when wave rocks ship, wave, which enters to subtract, shakes wave absorption wall 1
Space is formed between watertight wall 2 and platform board 5, platform board 5 can reduce wave heights, which reduces the height of wave
And the frequency of wave is reduced, so that ship has been achieved the effect that subtract and is shaken wave absorption.
It is provided with round discharge orifice 6 on platform board 5, is attained by under various drauht operating conditions and subtracts the effect for shaking wave absorption.
Watertight wall 2 separates seawater and ship inner space, does not influence ship built-in function.
Wave enters wave absorption wall 1, and to encounter watertight wall 2 reversed, and reversed wave and next wave entered wave absorption wall 1 with
Wave between watertight wall 2, contrary, wave is cancelled out each other, and reaches wave dissipation effect, please as shown in Figure 5.
Platform board 5, which plays, forces down wave heights, and the wave of opposite direction is cancelled out each other, and wave dissipation effect is reached.Wave is in water
It is moved back and forth between close wall 2 and wave absorption wall 1, plays the effect for subtracting and shaking, please as shown in Figure 6.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
