Description

[0001] DRILLSHIP HAVING FIRE WATER MONITOR [0002]

The present invention relates to a drill rig, and more particularly, to a drill rig to which a fire extinguisher monitor is applied instead of a fire extinguishing water nozzle.

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.

On the other hand, a fire system and a bilge system are installed in the drill ship to suppress the fire. "Bilge" means that water leaking from the shell or pipe through the ship, water contaminated with oil from the deck, or water from the cargo is placed on the bottom of the vessel, and the wastewater is borrowed .

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic diagram of a fire system in a conventional drill string.

As shown in Fig. 1, the conventional drill rig has two fire pumps p at the stern part and one fire pump p at the forward part. The fire pump p, (SC, seachest) to provide seawater to the corresponding area marked in boxes, for example, a drill floor, engine room, thruster room, well test area, and so on.

On the other hand, on the upper part of the main deck, there is a large area. In this large area, a pipe surrounding the whole area and a spray nozzle are installed to suppress the fire.

However, this method requires efficient piping and spray nozzles to surround a large area, which is not efficient due to a lot of working time as well as working time.

Also, from the maintenance point of view, it is difficult to find any leaks even if leaks occur in any one of the pipelines.

Therefore, there is a need for improvement measures to improve such inefficiency.

Further, in the conventional drill ship, a bilge system is provided to handle bilge, and the bilge system is configured to purge and discharge the above-mentioned bilge.

Generally, a bilge system for discharging such bilge to the outside of the hull as the bilge (wastewater to be kept at the bottom) becomes flooded due to seawater, rainwater or various other causes even when the ship is under voyage or berth .

A conventional bilge system includes a bilge pump for pumping bilge, and a total of four bilge pumps are provided, two at the forward portion and two at the aft portion.

In addition, the bilge pump is used separately from the fire pump (p) described above. However, in the case of the fire pump (p) and the bilge pump, the number of use thereof is small compared with the number of the installation.

Recently, as the drilling area has been transferred to the deep sea, drilling rigs have been increasing in price due to the installation of equipment for deep drilling. Therefore, it is required to take measures to reduce cost by eliminating unnecessary equipment.
