Recently, along with the development of oil exploration technology on the seabed, large oil companies have felt the necessity of drilling rig with drilling facilities suitable for development of marginal field or deep sea oil field, It is a reality that is actively searching for development.

Typical offshore structures that perform drilling operations include drillships, drilling rigs, jack-ups, and drilling-barges. Drilling and drilling rigs are available for drilling in the deep sea.

The drill ship is an offshore structure that is equipped with advanced drilling equipment and is built in a shape similar to that of a ship so that it can be sailed by its own power. It is capable of collecting crude oil and gas in deep sea area where an offshore platform can not be installed, It is advantageous to finish the drilling at the point and move to another point to perform drilling again.

The drilling rig is a semi-submersible offshore structure, also known as a semi-submersible rig. This semi-submergible offshore structure includes Derrick, Crane, Winch A plurality of columns installed vertically on the lower surface of the deck to support the deck, and a plurality of columns connected to the lower end of the column to hold the floating state, And the pontoons that provide buoyancy for the hull structure. Accordingly, since the repair area of the hull structure exposed on the water surface is reduced, the movement characteristics of the hull structure, especially the up and down linear motion The linear motion of the rotor) can be reduced. Therefore, it is possible to input even in the sea area where the marine environmental load is relatively high, and it is putting a lot of effort into the development of the deep sea oil field.

The above-mentioned drill ship or semi-submergible offshore structure can be used for exploration work for finding oil or gas existing in the underwater floor, observation of the seabed situation due to drilling work, or a sea such as BOP or X-mas tree A remotely operated vehicle (ROV) is used for maintenance and maintenance of the equipment.

Since these unmanned submersibles have to be operated in sea water, there have been various problems in moving them from the hull to the sea water or from sea water to the hull.

For example, in order to put an unmanned submersible into seawater, a wire is connected to a crane or a winch, and then the unmanned submersible is lifted while the wire is connected to the unmanned submersible. Thereafter, The unmanned submersible is shaken and collides with the hull to cause mutual damage and loss.

Furthermore, as the volume of the unmanned submersible increases, the movement is more sensitive to the effects of the wind, and the wire has to be specially designed to withstand the load of the unmanned submersible, and the inconvenience of repeatedly checking or replacing there was.

In the case of a drill bit, the unmanned submersible handling system is safely moved by providing a guide rail on a side portion to solve the above-mentioned problem.

However, since the semi-submergible offshore structure is structurally impossible to install the guide rails, it is inevitably exposed to the above-mentioned problems, and the efficiency of the submarine exploration work using the unmanned submersible is deteriorated.

The installation process of the cursor guide structure 400 is performed by moving each of the first wire 110, the first auxiliary wire 111, the second wire 120 and the second auxiliary wire 121 of the winch part 100 to the cursor guide The first auxiliary fixing member 445, the second auxiliary fixing member 442 and the second auxiliary fixing member 446 of the structure 400 to be connected to the winch unit 100 The cage guide structure 400 is lowered to the pontoons 4 by the application of the power and the hull connecting portion 410 is installed on the side wall of the pontoon 4 and the hull connecting portion 410 provided on the rear side of the frame portion 430 The fitting operation is completed by fixing the hull connecting portion 410 and the engaging portion 420 to the locking pin 428 by matching the engaging portion 420 to be connected to the hull connecting portion 410.

The third wire 130 and the fourth wire 140 of the winch unit 100 are drawn out to form the third fixing member 443 of the cursor guide structure 400 provided on the pontoon 4, The guide wire of the cursor 200 is completed.

The process for injecting the submersible 300 into the seabed is performed by connecting the fifth wire 150 to the submersible 300 while the third and fourth When the fifth wire 150 is loosened by holding the wires 130 and 140 and applying power to the winch unit 100, the third and fourth wires 130 and 140 and descends to the cursor guide structure 400 so that the cursor 200 is seated in the guide structure 400 and then the fixed state of the submersible 300 is released from the cursor 200, 5 wire 150 is continuously released, the submersible 300 slowly sinks into the sea water due to its own weight and descends to the sea floor.

When the fifth wire 150 is wound by applying power to the winch unit 100 after the submarine surveying operation is completed, the submersible 300 is caught by the guide structure 400, The cursor 200 is lifted up to the cursor 200 and the submersible 300 is fixed to the cursor 200. When the fifth wire 150 is continuously wound, the cursor 200 moves the third and fourth wires 130 and 140 And is then raised and lowered to the submersible room (5).

As described above, according to the present embodiment, the cursor guide structure 400 can be installed on the side wall of the pontoon 4, so that the cursor guide wires 130 and 140 can be moved from the submersible room 5 to the cursor guide structure 400 The cursor 200 can be lifted and lowered along the cursor guide wires 130 and 140 in a sliding manner without any fluctuation due to an external force such as wind or waves and the submersible 300 accommodated inside the cursor 200 It can be safely transferred from the hull to sea water or from seawater to the hull.

In this embodiment, the cursor guide structure 400 is manufactured in a removable type so that the cursor guide structure 400 is stored in the submersible room 5 at the time of operation and installed at the side wall of the pontoon 4 at the time of underwater operation It is free from frictional resistance at the time of navigation, so that the efficiency of operation can be increased, and the efficiency of the submarine exploration work can be improved during underwater operation.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification and the modification are possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
