Description
Technical field
The utility model belongs to Naval Architecture and Ocean Engineering technical field, is related to a kind of reduction drill ship or drilling platforms moon pool
The device of middle liquid sloshing, in particular to one kind can be opened and closed moon pool retaining device.
Background technique
Increase in demand with the mankind to the petroleum gas energy, the exploitation of land resources are no longer satisfied existing stone
Oil supply, offshore oil exploration and exploitation are very urgent, and various novel marine settings continue to bring out under the new situation herein.Ocean
Resource becomes the big treasured place that the mankind obtain the energy, exploits object by emphasis of offshore oil especially, and is gradually turned to deeply by shallow sea
Sea.Drill ship and all kinds of drilling platforms drill the advantages such as waters is deep, and flexibility is good by it and show one's talent.Deep-sea brill is carried out at present
The marine structure of spy is mainly all kinds of drill ships and all kinds of drilling platforms.On drill ship and all kinds of drilling platforms, in order to put
Drilling equipment is set, guarantees stabilization when drilling well, can all be disposed with this structure of moon pool.Moon pool is normally in the middle part of platform, from upper
Deck leads directly to bottom.Various drilling equipments and pipeline are from moon pool by carrying out exploitation work.Since moon pool and seawater directly contact,
Climbing for whirlpool and wave can be generated after contact with sea water to moon pool pool wall.Wind, wave, stream collective effect under, seawater also can shape
It is moved at " rocking " of vertical " piston " movement and horizontal direction.Over time, impact failure is caused to offshore engineering structure；
That aggravates each freedom degree of offshore engineering structure simultaneously sways movement, so that work and rest environment become badly, to make ocean
Industry and on ordinary days life bring tremendous influence.
For moon pool structure, when works navigation, incoming flow is met with the forward position of moon pool first, forms whirlpool, whirlpool edge
Water (flow) direction constantly expands, after reaching moon pool at edge with pool wall collide, cause climbing for wave, the liquid level in moon pool due to
The effect of disturbance can also generate violent oscillation action, therefore, design a kind of wave that can effectively reduce and climb and wave oscillations
Device is highly important.
In order to cope with these adverse effects of moon pool, the measure mainly used at present has: adding in moon pool structure additional
Object, change moon pool shape and moon pool bottom add can open and close type flapper, at present both at home and abroad in the research of moon pool drag reduction
It is concentrated mainly on and adds damping sheet this aspect, damping sheet is typically placed at moon pool wall surface and moon pool bottom, is mainly used for inhibiting
Wave climbs, the impact for avoiding deck overflow, checking seawater to offshore engineering structure.And then reduce ocean engineering structure
Liquid sloshing in the moon pool for reducing ship or ocean engineering structure swayed.However, since moon pool space is limited, addition damping
Plate will certainly reduce the effective operation space of moon pool, and the presence of additives can also have a certain impact to the arrangement of drilling equipment,
Hamper normal drillng operation.Existing moon pool, which subtracts rolling measure, also to be made in moon pool form and is changed, such as by rectangle moon pool angle
Portion changes into triangle or fillet, and such structure can improve the intensity of moon pool, but will not inhibit climbing for wave in moon pool,
Will not prevent to meet before and after fluid in moon pool the moon pool space for causing to resonate, while wasting very much.
