Description

[0001] DRILLSHIP HAVING A SEPARABLE DRILL PIPE SUPPORTER [0002] BACKGROUND OF THE INVENTION [0003]

The present invention relates to a drill ship, and more particularly to a drill ship in which a drill pipe support for supporting a drill pipe located at an outermost position of a drill pipe supporting the drill pipe is detachably provided.

Due to the rapid international industrialization and industrial development trends, the use of global resources such as oil is gradually increasing, and thus the stable production and supply of crude oil is becoming a very important issue globally.

For this reason, recently marginal field or deep-sea oil development has been economically feasible, which has been neglected due to economic difficulties so far. Therefore, with the development of submarine mining technology, drilling facilities suitable for the development of such oilfields A drilling rig equipped with a hull has been developed.

Conventional submarine drilling has been mainly used for a rig ship or a fixed platform for underwater drilling that can be sailed only by other tugboats, and where submarine drilling is carried out with a mooring device anchored at one point in the sea.

In recent years, a so-called drillship has been developed to be equipped with advanced drilling equipment and manufactured in the same form as a general ship so that it can be sailed by its own power, and is used for underwater drilling. In order to develop the small-scale oilfield, depending on the working conditions that need to be moved frequently, these drillships are constructed so that they can navigate with their own power without a tugboat.

A drill ship has a moon pool in which a riser and a drill pipe move up and down at the center, and a derrick where various drilling rigs are integrated on a deck of a drill ship.

 The main deck is provided with a mud module to which mud supply related equipment for supplying the mud required for drilling is disposed, and a plurality of drill pipes are stacked on the upper surface of the mud module.

The drill pipe mounted on the mud module is supported by a plurality of drill pipe supports provided on the mud module. A drill pipe support disposed at the outermost edge of the plurality of drill pipes is welded to the end of the pipe rack using a fixed type or H-beam, as shown in Fig.

In this case, in order to maintain the drill pipe support disposed at the outermost edge, it is necessary to remove the welded part, and the lower part of the welded part must be reinforced so that maintenance is difficult.

The above-described technical structure is a background technology for assisting an understanding of the present invention, and does not mean a conventional technology widely known in the technical field to which the present invention belongs.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a drill pipe support which is provided on a mud module and is disposed at an outermost edge of a plurality of drill pipe supports for supporting a drill pipe, It is easy to provide.

According to an aspect of the present invention, there is provided a mud module disposed on the main deck, in which mud-related equipment supplied to drilling holes is disposed; And a plurality of drill pipe supports for supporting a drill pipe provided at an upper portion of the mud module, wherein a drill pipe support provided at an outermost edge of the mud module among the plurality of drill pipe supports is detachably provided Wherein the drill-out is provided with a detachable outermost drill pipe support.

The drill pipe support provided at the outermost edge of the mud module may be provided with a detachable outermost drill pipe support, wherein a lower end is inserted and supported in a support groove provided in the mud module.

The drill pipe support provided at the outermost edge may be supported by a bracket whose one end is coupled to the mud module and the other end is coupled to the drill pipe support.

The bracket coupled to the mud module may be inserted into a groove provided in the mud module and may not protrude from the upper surface of the mud module.

A lifting lug may be provided at an upper end of the plurality of drill pipe supports.

Embodiments of the present invention provide for the maintenance of the drill pipe support in a detachable manner by providing an outermost drill pipe support among the plurality of drill pipe supports provided in the mud module, It can be facilitated.

2 is a side view schematically showing a drill ship according to an embodiment of the present invention.
3 is an enlarged view of the area "A" in Fig.
Fig. 4 is an enlarged view of the area "B" in Fig.

In order to fully understand the advantages of the present invention, its operational advantages, and the objects attained by the practice of the present invention, reference should be made to the accompanying drawings, which illustrate preferred embodiments of the present invention, and to the description in the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

2 is an enlarged view of an area "A" in Fig. 2, Fig. 4 is an enlarged view of an area "B" Fig.

As shown in these drawings, the drill ship 1 according to the present embodiment includes a mud module 10 provided in the main deck MD and arranged with mud-related equipment supplied to the drill hole when drilling, And a plurality of drill pipe supports 20 provided on the upper side of the drill pipe support 20 for supporting the drill pipe and mounted on the outermost edge of the drill pipe support 20.

As shown in FIG. 2, the mud module 10 is a place provided in the main deck (MD) to produce a mud necessary for drilling or to provide a mud-related equipment for supplying the drill hole. The inside of the mud module 10 has a multi- .

1, a plurality of drill pipe supports 20 are provided on the upper surface portion of the mud module 10, and a plurality of drill pipe supports 20 are mounted on the upper surface portion of the mud module 10 And prevents the drill pipe from collapsing or falling from the mud module 10 to the main deck (MD).

A drill pipe support 20 disposed at the outermost edge of the mud module 10 among a plurality of the drill pipe supports 20 provided in the mud module 10 is fixed to the mud module 10 in a welding manner.

In this case, if the maintenance of the drill pipe support 20 is required, the weld portion is removed and then re-welded. Therefore, the maintenance work is not easy and the lower portion of the drill pipe support 20 has to be reinforced.

3, a support groove 11 is provided at the outermost edge of the mud module 10, and a lower end portion of the drill pipe support 20 is inserted into the support groove 11. In this embodiment, The above-described drawbacks can be compensated for by providing the drill pipe support 20 in a detachable manner.

4, the one side is detachably bolted to the mud module 10 and the other side is connected to the bracket 30, which is detachably bolted to the drill pipe support 20, So that the lower end of the drill pipe support 20 can be more firmly supported.

The present embodiment may provide an insertion groove (not shown) having a shape corresponding to the bracket 30 that contacts the mud module 10 so that the bracket 30 does not protrude from the mud module 10.

3, a lifting lug 21 may be provided at the upper end of the drill pipe support 20 in this embodiment and the drill pipe support 20 ).

In this embodiment, in addition to the drill pipe support 20 provided at the outermost edge of the mud module 10, another drill pipe support 20 may be detachably provided.
