Description
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, ≪ / 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.

A lock or a locking mechanism may be provided on one side of the connection wire to prevent the main body from being detached in a state where the main body is mounted on the square column.
The main body may be installed in a streamlined elliptical shape to increase the straightening performance by reducing the resistance of the water when the offshore structure is towed.
The auxiliary body may be formed in a rectangular shape so as to be mounted on the first and second fixing portions of the main body while the inside of the auxiliary body is in close contact with the auxiliary body.
The driving unit includes a propeller that is installed on a second fixed portion of the main body and uses a propeller propeller or a thruster to generate a propelling force for moving the main body, an actuator installed on the second fixed portion of the main body, And a controller electrically connected to the actuator.
The adduct may be installed in each of the round column or square column installed in the offshore structure.
As described above, according to the towing direction control and turning attachment of an offshore structure according to the present invention, it is possible to desorb and attach the detachable adherent to a column of an offshore structure, thereby enabling reuse on other offshore structures.
Also, since the present invention can be easily detached from a column of an offshore structure, it is easy to turn and turn, thereby reducing the number of tugboats required for wet towing of an offshore structure, thereby reducing a towing cost.
