It is a primary object of the present invention to overcome the shortcoming that prior art is present, and a kind of suspension type diving for transporting installation suitable for ocean platform is provided and refuted and its application method, suspension type diving of the present invention is refuted using upper hull and pontoon split-type design, after ocean platform is transported to destination, by filling ballast water to pontoon, pontoon is set to drive ocean platform to dive under water completely, again by carrying gantry crane, can be by ocean platform righting, realize ocean platform transport and install, installation process need not employ large-scale floating crane.
The purpose of the present invention is realized by following technical scheme：
A kind of suspension type diving is refuted including pontoon, upper hull, lifting column, stopping means, gantry crane, it is characterized in that the port and starboard top of the pontoon is respectively arranged with 1 upper hull, the lifting column passes through its lower end after the upper hull to be fixedly connected with the pontoon, the upper hull can be moved up and down along the lifting column, the stopping means is arranged on the lifting column, height of the stopping means on the lifting column can be adjusted, and the gantry crane is arranged on the lifting column top.
The pontoon bow stern two ends offer notch.
The upper hull is strip.
The lifting column is 4, is symmetrically mounted on the corner location of the pontoon.
The gantry crane is mounted on 2 lifting column tops of the pontoon stern.
A kind of suspension type diving is refuted its transport, the method for installation marine structure and comprised the following steps：
（1）Marine structure is placed on the upper deck of pontoon and fixed, target job location is dragged to by towboat；
（2）Suspension type diving refute cast anchor it is fixed after, towing cable be connected with marine structure rear end, pontoon ballast is sunk, marine structure enters water, until marine structure is in from the state of floating, after upper hull is contacted with stopping means, stopping is to pontoon ballast；
（3）Marine structure is hauled out using tugboat, after marine structure top suspension centre is reached below gantry crane, the suspension hook of gantry crane be connected with ocean structure top suspension centre；
（4）Pontoon is lifted, recovered to initial floating state；
（5）Towing cable is discharged, marine structure is gradually tilted, after marine structure righting, under the lifting of gantry crane, transfer marine structure, until marine structure is transferred to mud face, installation.
Beneficial effects of the present invention：Suspension type diving of the present invention is refuted using upper hull and pontoon split-type design, after ocean platform is transported to destination, by filling ballast water to pontoon, pontoon is set to drive ocean platform to dive under water completely, again by carrying gantry crane, ocean platform righting can be realized ocean platform transport and be installed, installation process need not employ large-scale floating crane.
The present invention will be further described with reference to the accompanying drawings and examples.
