Description

Drill {DRILLSHIP}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drill ship, and more particularly, to a space capable of additionally installing a cabin in which a crew resides and a drill rig capable of securing the safety of the crew.

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.

In recent years, however, drill ships and semi-submersible rigs have been developed that are equipped with advanced drilling equipment and built in the same form as general ships so that they can navigate with their own power, And has been used in production.

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

In recent years, the development of oilfields in the deep sea has led to an increase in the number of drilling equipment, including drill pipes, riser pipes, and mud equipment, thereby increasing the demand for crew handling drilling equipment.

As shown in FIG. 2, the previous drill ship is disposed in the upper area of the main deck MD, and most of the cabin deck 20 provided with the cabin in which the crew resides is not extended to the widthwise edge of the hull There was a lot of empty space.

In this case, there is no problem when the number of the crew members residing in the cabin deck 20 is between 180 and 200, but when there are more than 240 crew members, the cabin is absolutely insufficient.

Therefore, considering the recent deep-sea drilling work environment, it is required to improve the cabin deck so that a sufficient number of crew can dwell comfortably.

In the previous drill ship, a lifeboat is provided at the port edge and starboard edge of the hull as shown in FIGS. 1 and 2 so that the crew can safely escape at the time of an accident.

However, the previous drill ship was open to the stern of the area where the lifeboat was installed, which was dangerous because the crew was exposed to flames or poison gas during the fire. Therefore, improvement measures are also required.

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