Description

[0001] APPARATUS FOR TOWING DIRECTION CONTROL AND TURNING OF OFFSHORE STRUCTURE [0002]

The present invention relates to a towing direction control and turning attachment of an offshore structure, and more particularly, to a towing direction control and swing attachment capable of detachably attaching to a column of an offshore structure and controlling the turning direction of the offshore structure during towing, &Lt; / RTI >

Floating marine structures have been mainly used for oil drilling, but recently their use has been spreading to marine power plants and oil storage facilities.

As marine petroleum development progresses to deeper water depths, floating offshore structures are required to have floating offshore structures due to the high cost of drying.

Floating structures for oil drilling have the proposition that mobility and stability should be guaranteed at the same time.

In other words, if the drilling fails, it must be possible to move to another sea area immediately, and the drilling pipe must be secured enough to not apply excessive force to the drilling pipe. In other words, it is necessary to design a structure that is floated in the floating state and has less movement due to waves and the like.

Therefore, a semi-submergible offshore structure which is advantageous to float with less motion has appeared.

Semi-submersible offshore structures are floating structures with four or six columns, and the horizontal pontoon, which connects each column, creates buoyancy. All of the pontoons and part of the column are operated with locks and are called semi-submerged offshore structures. There are pontoons which act as buoyancy, topside which is a superstructure acting as a working space, and several columns connected therebetween.

As a method of towing offshore structure, there is Dry Towing which carries large marine structure on a shipping vessel, and Wet Towing which tows a large offshore structure by connecting it to a towboat.

However, as marine structures have become larger, there has been a shift from dry towing to wet towing to transporting large, offshore structures in the shipyard to the operating area. The biggest reason is due to the capacity limit of shipping vessels capable of loading large offshore structures.

Wet Towing takes a long time to the operating area and it is difficult to increase the towing speed due to the resistance due to environmental conditions in the long distance towing process. Especially, the underwater shape of the offshore structure greatly affects the towing speed.

1, the shape of the pontoon 330 and the column 320, which are submerged in the water, has a shape perpendicular to the traveling direction of the offshore structure 300, which increases the water resistance And the time and energy consumed for towing speed reduction and towing increase.
