Description
Technical field
The present invention relates to ocean engineering, more particularly to a kind of Semi-submersible type hoisting load of platform water system and its operating method.
Background technology
Semi-submersible type hoisting platform, so that its capacity of anti-storm is strong, floor space is big, deck changing load is big, useful load is big, suitable
Answer the advantages of depth of water scope is big, personnel's accommodation is more, the optimum carrier as ultra-large type crane.Semi-submersible type hoisting platform one
As have dispatch navigation, hoisting operation, storm oneself the various working such as deposit, its special operation function demand is set to ballasting system
Meter proposes higher requirement.
Boat form Semi-submersible type hoisting platform is generally upper flat by two lower floating bodies, three~five pairs of symmetrical columns and one
Platform is constituted.When dispatching navigation, to reduce resistance, waterline is located at lower floating body；In hoisting operation, to ensure that it is good that operation has
Good seakeeping capacity, waterline is located at column middle；When depositing operating mode certainly, to improve the weatherliness of platform, now waterline
Positioned at column bottom.Platform drinking water and displacement difference due to three kinds of operating modes is huge, therefore passes through the lower floating body in main hull
It is interior that substantial amounts of ballast tank and ballast water injection and discharge system are set, to meet the conversion needs under these three operating modes.
Because Semi-submersible type hoisting platform needs to lift by crane thousands of up to ten thousand tons of weight within the extremely short time in hoisting operation,
And sling load will produce huge tilting moment to platform, significant impact is produced to platform floading condition and stability.To ensure safety
Operation, it is necessary to the tilting moment produced in the substantial amounts of ballast water of Opposite side loading with partial offset lift heavy.In addition, being carried in crane band
During revolution, the direction for the tilting moment that huge hoisting heavy is produced changes in a short time, it is also necessary to pass through ballast water
Fast velocity modulation carry to balance the change of tilting moment, otherwise platform inclination can be caused to aggravate, and slew gear is in descending fortune
Turn state, this is breakneck.Therefore to ensure hoisting operation safety, substantial amounts of pressure is set in the column domestic demand of main platform body
Cabin and the anti-tune loading system that inclines are carried, the fast velocity modulation for ballast water is refuted, and this is that conventional Semi-submersible type hoisting platform is unexistent, Hou Zheyou
In adjusting, carrying capacity is small, adjust load rate request not high and the pump pressure loading system single typically using function, and it can not meet semi-submersible type and rise
Huge quick, the efficient tune adjusted under carrying capacity conditions of demand of galassing platform, which carries function, to be needed.
The content of the invention
It is a primary object of the present invention to overcome the disadvantages mentioned above that existing product is present, and a kind of Semi-submersible type hoisting is provided and put down
The ballast system and its operating method of platform, it uses the Combined press that two kinds of ballast modes of ballast pump and compressed air are combined

Example IV：Column ballast tank is losing the quick row load operating process in emergency circumstances such as hook suddenly, such as Fig. 6 institutes
Show.
In Semi-submersible type hoisting platform during hoisting operation, such as occur suddenly lose hook emergency when, it is necessary to pass through
Pressure/row carries operation and makes quick adjustment to platform floading condition.Lose the urgent feelings of lifted load suddenly when a side of a ship crane job
Under condition, start compressed air ballasting system 4, quickly discharge to resist to incline in another side of a ship column using compressed air and adjust load ballast water
Mode carries out the anti-tune that inclines and carried, and its step is as follows：, should when larboard loses sling load suddenly in the crane for carrying out hoisting operation
The sensor and associated control signal that anxious emission control unit 10 has by itself are sent rapidly to compressed air ballasting system 4
The instruction of right column ballast tank Quick drainage, starboard high position draining valve 9 is opened, while compressed air enters right column ballast tank 3,
Ballast water quickly discharges outboard under compressed air and self gravitation effect in the right column ballast tank；When starboard is being risen
When the crane of heavy work loses sling load suddenly, sensor and correlation that emergent emission control unit 10 has by itself
Control signal sends rapidly the instruction of left column ballast tank Quick drainage, larboard high position draining valve 8 to ballast air ballasting system 4
Open, make while compressed air enters ballast water in left column ballast tank 2, left column ballast tank in compressed air and self gravitation
Under, outboard is quickly discharged, the anti-heel effect of ship is reached, reduces platform angle of heel, it is ensured that the security of platform.
The content not illustrated in the embodiment of the present invention is prior art, therefore is no longer repeated.
The operation principle of Semi-submersible type hoisting load of platform water system and its operating method of the present invention：Adjustment is needed to eat in platform
In the case of water, by adjusting the turnover for carrying seawater to complete in lower floating body ballast tank and left and right pillar ballast tank.
When the anti-tune that inclines is carried (crane lifting rotary phase), the ballast water of left and right pillar internal ballast tanks needs to carry out phase
Intermodulation refutes to keep platform in balance, and the total Water in the case of this in load of platform cabin keeps constant, adjusts and carries by being pumped load mode
Carry out；In the case of losing hook suddenly, to keep the balance of platform, it is necessary to by the ballast water in the column ballast tank of the reverse side of lifting
Quick discharge outboard, such a tune carries mode and carries out operation completion by compressed air ballasting system.
Lower floating body ballast tank carries out gravity feed and can quickly adjust platform drinking water by compressed air draining.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, it is all
It is any simple modification, equivalent variations and the modification made according to the technical spirit of the present invention to above example, still falls within
