Description

DRILLING SHIP

Field of the Invention [0002] The present invention relates to a drill ship, and more particularly, to a drill ship in which an emergency generator room is disposed in a top deck of a residence.

With the rapid development of international industrialization and industry, the use of earth resources such as oil is gradually increasing, and thus the stable production and supply of crude oil is becoming an increasingly 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 which can be sailed only by other tugboats and which is used for drilling underwater at anchor point on the sea using a mooring device.

However, in recent years, a drillship having the same shape as that of a general ship has been developed and installed in underwater drilling so as to mount a cutting-edge drilling rig and to navigate with its own power.

In order to develop small-sized oilfields, drillships are designed to be able to navigate powerlessly without a tugboat, depending on the working conditions that need to be moved frequently.

On the other hand, special ships such as drillships or semi-submersible rigs are equipped with emergency generators to cope with emergency situations such as power outages. The emergency generator is provided in the emergency generator room and is connected to the emergency generator engine.

FIG. 1 is a view schematically showing a position where an emergency generator room is provided in a drill ship according to an embodiment of the prior art. FIG. 2 is a view showing a flow of cooling air in an emergency generator room according to an embodiment of the related art And FIG. 3 is a view showing maintenance of equipment of an emergency generator room according to an embodiment of the prior art.

As shown in FIG. 1, in an embodiment of the prior art, the emergency generator room 110 is provided in the main deck MD where the docking station LQ is located. In the emergency generator room 110, an emergency generator and an emergency generator engine are installed, and the emergency generator is operated in an emergency such as stopping the main generator in normal operation. Then, the air conditioning room 120 is located on the C-deck where the residence is located.

According to the prior art, since the emergency generator room 110 is located in the main deck MD, the vibration and noise generated when the emergency generator is operated are transmitted to the cabin area adjacent to the emergency generator room 110 to prevent the pleasant living of the cabin area . As shown in FIG. 1, it is necessary to install a structure reinforcing pillar by being installed in an area protruding from the upper decks. Also, the air conditioning room (120) is located near the residence, and the vibration and noise generated from the equipment of the air conditioner are transmitted to the residence so that it interferes with the pleasant living of the residence.

2, arrows represent the flow of cooling air. As shown in FIG. 2, the emergency generator room 110 is composed of two decks, and the cooling air is sucked into the upper deck and flows to the lower deck, and is discharged from the lower deck. That is, since the flow path of the cooling air is bent, the flow of the cooling air is not smooth.

1, the emergency generator room 110 is located in the main deck, and the residential unit is located in the upper portion of the emergency generator room 110. As shown in FIG. Accordingly, in order to maintain the equipment of the emergency generator room 110, the equipment is lifted out of the hull by using a monorail, a trolley, and a hoist as shown in FIG. In Fig. 3, the arrow indicates the movement path of the equipment. Therefore, a monorail, a trolley, and a hoist must be installed, and a safety problem may occur as the equipment is moved inside the emergency generator room 110.

That is, according to the related art, vibration and noise of the emergency generator room 110 and the air conditioning room 120 interfere with the pleasant living of the cabin space, the flow of the cooling air in the emergency generator room 110 is not smooth, There arises a safety problem in maintenance of the equipment in the generator room 110, and there is a problem such as an increase in material cost due to the installation of structural reinforcing columns and monorails, trolleys and hoists.

4 and 5, the drill rig according to the embodiment of the present invention is provided on the top deck (TD) of the resident port LQ of the emergency generator room 410 and the air conditioning room 420.

The emergency generator room 410 and the air conditioning room 420 are provided on the top deck so that the emergency generator room 410 and the air conditioning room 420 are separated from the cabin space and the emergency generator room 410, The noise of the air conditioning room 420 is not transmitted to the cabin area, so that the cabin area is comfortable and the space for utilizing the main deck is enlarged.

5, an emergency generator 411, an emergency generator engine 412, and a radiator 413 are installed in the emergency generator room 410. The emergency generator 411 is activated when an abnormality occurs in the main generator to generate electric power and supply electric power to the drill rig. The emergency generator engine 412 then generates the mechanical energy necessary to combust the fuel to operate the emergency generator 411.

The temperature of the emergency generator room 410 is raised by the heat generated during the operation of the emergency generator engine 412 and the emergency generator 411. The radiator 413 radiates the hot air from the emergency generator room 410 to the air generator 414. The radiator 413 radiates the hot air from the emergency generator room 410 to the air generator 414, And is discharged through the discharge portion 414.

[

The hatch 416 may be hinged to the ceiling of the emergency generator engine room 410 so as to be openable or closable, or may be bolted or slidably coupled to be openable and closable.

A pedestal crane can lift the equipment to be maintained through the hatch 416 above the emergency generator room 410 and transport it to a lay down area. If equipment is to be repaired in the laydown area, or if it is difficult to repair within the drill ship, it may be transported overland by a transport ship and repaired onshore.

According to the embodiment of the present invention, the emergency generator room 410 is provided on the top deck so that the ceiling portion of the emergency generator room 410 is in contact with the outside, and the maintenance is performed through the hatch 416 of the ceiling portion of the emergency generator room 410 The equipment can be removed immediately. Therefore, the maintenance of the equipment is convenient, the safety is improved, the equipment such as the monorail, the trolley and the hoist is not needed, and the material cost can be greatly reduced.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
