Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a roll-up door and a hinged door device,

The present invention relates to a door comprising a large roll-up door and a hinged door installed in a storage area of a BOP (Blowout preventer), which plays an important role in the drilling of a drill ship.

More precisely, it has been suggested that the use of non-ozone as an equipment to prevent pressure and explosion in oil wells when drilling crude oil from the sea floor, Protective and pre-work space for pre-commissioning and maintenance, and space for overhead cranes for transport and adjustment of non-ops (BOPs). And the internal overhead crane makes it possible to move the BOP equipment inside and out.

The present invention provides a space for loading and unloading equipment on a drill ship for the trial operation and inspection for storing and installing BOP (Blowout Preventer) equipment, which is a device for preventing pressure and explosion suddenly occurring in the well when the drill ship is drilling from the sea floor .

In general, the height of the stacking space is low so that the stacking space of the non-ope- rization equipment installed in the space on the deck of the conventional drill ship can be stored only through the non- The trolley conveying device is installed on the floor and the outside of the loading space is equipped with a rail and a skidding cylinder around the loading space door for the operation of the trolley equipment. ) Were installed.

In such a conventional apparatus, when the non-opy equipment is stored, the non-opy trolley equipment is kept fixed on the upper part of the transfer device and is stored. During this time, the non-op trolley equipment transferring device is stored inside the loading space, It protects workers and equipment from rough sea environments, including rain, wind and snow due to change.

In order to move the non-OPK equipment to the ground and move to the outside of the loading space in order to install the non-OPK equipment as described above, the OPK door is first placed on the trolley equipment while the open door is opened, To move the non-OPE equipment out of the loading space.

The non-opi equipment moved to the outside is lifted from the non-op trolley equipment conveying equipment by unlocking the safety device and using the crane installed on the outer deck, moving from the drill ship to the ground or moving to the work place to install it.

Thus, conventionally, it is possible to move or store only a few operations when installing, moving, unloading, and storing non-OPU equipment.

In addition, the rail and the skidding cylinder for operating the trolley equipment installed outside are rapidly aged by the external environment, are not beautiful in appearance, are restricted in space, and are inconvenient for the operator to move and use many.

The present invention relates to a marine environment with external rain, wind and snow for commissioning and inspection for the storage and installation of BOP equipment, which is a device for preventing sudden pressure and explosion in a well when drilling in the ocean. The overhead cranes used for moving (non-adjusting) equipment can be stored inside the loading space. In addition, when the inside and outside of the non- By making it possible to use it by protruding out of the open door, it is possible to use the space outside the drill ship by minimizing the work space, and to simplify the moving procedure, thereby making it easier to move and operate the non-operative equipment.

The present invention relates to an overhead crane, which comprises a main frame portion in which left and right frames for installing left and right rails capable of moving before and after an overhead crane are arranged in parallel, a first blocking wall provided with a door for accessing the operator, And a second door which is opened to the right. The upper door frame part is provided with a first door which opens to the left and a second door which opens to the right. And a hinged door opened at an angle of 90 degrees forward, so that it can be conveniently operated by moving the overhead crane forward and backward in a non-OPK equipment storage area and protecting the equipment by sealing the inside.

Since the first door and the second door can be opened to the left and right at an angle of about 106 degrees after the large open door is opened, the overhead crane inside the working space can move to the inside / outside of the storage space, It is possible to secure a work space that is wider than the door of the door, so that it is not limited by the size of the equipment and cargo. In addition, it is possible to transport and manipulate the overhead cranes at one time without mounting the non- And the utilization of the space on the deck is also high due to the absence of the rail and the skidding cylinder of the conventional trolley conveying apparatus.
