Description

FIELD OF THE INVENTION [0001] The present invention relates to an isolated room structure of a floating structure having an independent fire prevention facility,

The present invention relates to an isolated room structure of a floating marine structure having an independent fire protection facility, and more particularly, to a marine structure such as a drill ship having a relatively high risk of fire in various rooms including an engine room and a work room. Of the floating structure with the independent fire protection facility which can improve the efficiency in the fire / digestive aspect and to make the economic efficiency from the constitutional aspect by constructing the fire installation only for the relevant components The present invention relates to an isolated room structure.

Along with the development of submarine mining techniques, drilling lines have been developed with drilling facilities suitable for marginal field or deep-sea oil field development.

Conventional submarine drilling is mainly used for a rig ship or a fixed platform for underwater drilling that can be sailed only by other tugboats and which performs submarine drilling with anchorage at one point on 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 drilling underwater. Depending on the working conditions that often need to be moved in order to develop small-sized oilfields, these drillships are constructed so that they can navigate with their own power without a tugboat.

On the other hand, a float-type offshore structure such as a drill ship has a moon pool in which a riser and a drill pipe move up and down, and a deck of a drill ship, (derrick) is installed. And an engine room or a work room in which various related equipment including an engine for operating various drilling equipment and the like are installed.

For example, in the case of a drill ship, a fire or gas system applied to the engine room creates a separate room or compartment in various sections of the engine room or work room . The main generator room, the purifier room, the throut room, and the switchboard room are separate rooms.

On the other hand, boiler or thermal fluid equipment for the production of thermal oil or steam may not be distinguished from other areas or designed as a closed area, In other words, 'auxiliary machinery').

Conventionally, boilers which are burned with thermal fluid are installed in the engine room in the same space as the other equipments without separate rooms or partition walls between the arranged spaces. Accordingly, when the fire of a boiler having a relatively high possibility of fire is generated, And there is a risk of fire to peripheral facilities. Therefore, in accordance with the SOLAS regulations, the entire engine room must be designated as MACH.SPACE OF CATEGORYA and a total flooding fire fighting system must be applied.

However, in the conventional engine room structure, there is a high possibility that the fire to the engine room or the work room is likely to spread due to the exposure installation of boilers having a relatively high fire risk, and the ship itself may collapse.

Also, in the past, it is necessary to apply the global emission / fire protection system to the engine room including the boiler facility or the entire work room, so that the fire extinguishing device must be operated even when the boiler or its peripheral devices are fired, , Thus increasing the fire protection capacity and operating to other equipment that operates normally. In addition, due to the arrangement of the boilers, it is necessary to install a fire detector in the engine room or the entire work room, There is no problem.

As a background related to the present invention, there is Korean Patent Publication No. 2000-0004706. However, if an abnormal symptom such as fire, flooding, or gas explosion occurs in any one of the port engine room, center engine room, starboard engine room, It is possible to selectively block the vehicle through the individual emergency control unit.

In order to solve these conventional problems, the present invention provides a fire-fighting / fire-extinguishing system in which fire-extinguishing equipment is constructed only for the components of a marine structure, The present invention provides an isolated room structure of a floating marine structure having an independent fire prevention facility capable of improving the efficiency in terms of efficiency and economic efficiency in terms of construction.

It is preferable that the boiler or the thermal oil heater installed in the engine room of the offshore structure and the auxiliary equipment of the boiler or the thermal oil heater are concerned with the fire.

Wherein the outside air supply duct is configured to independently introduce outside air in association with or not linked to the plurality of rooms, and the fire fighting concentration room includes a discharge duct for discharging air to the outside or another room adjacent to the fire fighting concentration room .

The outside air supply duct and the discharge duct may each include an opening / closing damper configured to control the air that flows into the outside air supply duct and is discharged from the discharge duct.

Wherein the fire extinguishing system is independently or in conjunction with or not associated with a plurality of rooms, the fire extinguishing system comprising: a fire detector for sensing smoke occurrence or temperature or flame and sensing whether fire has occurred; And a fire extinguisher that extinguishes the fire by spraying a repelling substance.

It is preferable that the fire suppressor of the fire extinguishing system is constituted of at least one of a water spray in which compressed fire water is sprayed, a minute photo sticker in which fire or fire extinguishing material is sprayed, and a complex suppressor in which the water spray or spray suppressor is combined.

According to the present invention as described above, it is possible to constitute a fire-fighting system for a device or an equipment only by isolating devices or equipment which are relatively exposed to fire risk in various rooms including an engine room or a work room of a marine structure, It is possible to reliably prevent the spread of the fire to other areas or the surrounding area and to provide an isolated room structure of a floating marine structure having an independent fire fighting facility capable of improving efficiency in terms of fire fighting / fire fighting.

In addition, according to the present invention, it is possible to provide a fire / fire extinguishing facility only in the concentrated fire fighting room, thereby simplifying the fire fighting / extinguishing device compared to the conventional one, It is possible to reduce the fire-fighting capacity by selectively injecting the fire only in the concentrated fire-fighting room, thereby improving the economical efficiency.
