Description

{Wintering system of marine structure for polar region and method of using wintering using the same}

The present invention relates to a cold weather system for an offshore structure and a cold weathering method using the same.

Due to the recent rapid industrialization, the use of resources such as oil has skyrocketed, and the stable production and supply of oil is becoming a very important issue. However, the oil field in the continental or coastal waters has already been drilled. In recent years, interest has been focused on the development of a deep-sea deep-sea oil field. Drilling is generally used to drill deep-sea oilfields.

Drill ship is an offshore structure that is equipped with advanced drilling equipment and is built in a shape similar to that of a ship so that it can be sailed by its own power. It is capable of collecting raw oil or gas in deep sea area where an offshore platform can not be installed, It is advantageous that the drilling can be terminated and the drilling can be carried out by moving to another point.

Such drillings include Derrick, which has a Moonpool structure in a vertically penetrating form and is located above the drum and has drilling rigs. Hereinafter, the process of drilling the bottom of the drill ship will be described.

First, the drill ship uses its own power to move to the drilling area and drives a Dynamic Positioning System (DPS) using a plurality of thrusters to maintain the position.

Thereafter, the drill bit is connected to the drill pipe by a drill bit, and a plurality of drill pipes are connected to the drill pipe by using a Hoisting System and a Handling System provided in Derrick, And the drilling pipe is rotated through a rotating system to form a borehole.

Once drilling is completed, Derek picks up the drill pipe, installs the casing pipe on the borehole, and performs the cementing process to fill the concrete between the casing pipe and the borehole. The drilling operation used and the casing and cementing work for installing the casing pipe are repeatedly performed to maintain the shape of the borehole having a certain depth.

When the casing pipe is installed enough to prevent the borehole from falling down, BOP (Blow Out Preventer) is connected to the riser to be connected to the borehole. In this case, the inside of the riser becomes the path of movement of the drill pipe and casing pipe.

However, lubrication and cooling of the drill bit in the drilling process, and processing of the crushed material such as rock mass produced in the borehole are required. Therefore, the drill feeds the mud to the inside of the drill pipe so that the mud is discharged at the end of the drill bit, and after the mud performs lubrication and cooling of the drill bit, (Mud Circulation System) is used. The recovered mud is re-used after the pulverized material is filtered.

The drillship repeatedly performs drilling, casing and cementing operations until the drill bit reaches the well, while driving this mud circulation system. In this case, as the diameter of the casing pipe used in the casing work becomes smaller, Drilling can be implemented continuously by replacing small drill bits.

As such, the drill rig has a system for installing and using pipes and risers, a system using a mud, and the like. In order to smoothly perform drilling work using such a system, a drill hole structure, a derrick structure, and a load structure Is required to be disposed within a certain space, so that research and development are being continuously carried out as a result of a high technological power being required.

In addition, as the area of untapped polar regions, which are abundant in natural resources, decreases, the development of polar roads will drill natural resources in the polar regions, and polar drills are being constructed to enable sailing and drilling in the polar regions.

It is essential to construct a winterization system to prevent freezing and freezing in cryogenic environment and to ensure smooth operation of equipment and safety of crew. In this wintering system, a heat-tracing cable is uniformly installed in an escape way or piping according to the numerical value of the winter performance determined at the designing stage and the class.

However, the heat tracing cable consumes a large amount of electric power of 6% to 7% of the total electric power for sea ice because of supplying heat using the heat line, and there is a problem that the total electric power consumption is large. There is a limitation in installing the heat tracing cable in the applicable area, and there is a problem that the reliability of the cold performance is low.

Here, the offshore structure (1) is used for the development of an offshore oil field, for example, a drill ship, a floating oil production storage and unloading facility (FPSO), a semi-submersible, And so on.

The weather and climate information providing unit 100 may collect information on weather and climatic conditions such as temperature and wind speed of an area where the polar sea-going structure 1 is located, and provide the information to the server 200, The weather satellite 110, the temperature sensor unit 120, the wind direction sensor unit 130, or a combination thereof. Here, the climate is the average state of the atmospheric phenomenon appearing over a long period of time in a certain region, and the meteorological state means the instantaneous atmospheric state changing momentarily in the corresponding region.

The meteorological satellite 110 may be a geostationary meteorological satellite that continuously revolves around the earth at an angular velocity equal to the rotation speed of the earth at an altitude of 35,800 km above the equator and continuously observes the weather information of a predetermined region on the earth, In addition, it is possible to collect satellite information affecting the polar marine structure 1 such as average yearly climate information and prediction information, and transmit the satellite information to a server 200 to be described later.

The temperature sensor unit 120 senses the temperature of each zone of the polar-field type offshore structure 1 in real time, and transmits the temperature sensing signal to the server 200, which will be described later, by wire or wire.

As shown in FIG. 2, the temperature sensor unit 120 detects the temperature of each of the first to n-th zones 1, A plurality of first to n-th temperature sensors 120-1, 120-2, ..., and 120-n disposed in the respective first to n-th temperature sensors 2-1, 2-2, , Each of the first to nth temperature sensors 120-1, 120-2, ..., 120-n senses the temperature of the corresponding zone in real time and transmits the temperature sensing signal to the server 200 to be described later by wire or wireless Of course it is.

The temperature sensed by each of the first to n-th temperature sensors 120-1, 120-2, ..., and 120-n may be different. For example, in a region where sunlight is well reflected, .

The directional wind speed sensor 130 can detect the directional wind speed of each zone of the polarized marine structure 1 in real time and transmit the directional wind speed sensing signal to the server 200 to be described later by wire or wire.

In step S720, the server 200 calculates the zone-specific heat loss data value using the information about the weather and the climatic environment.

In step S720, the zone-specific heat loss data values can be calculated differently in each of the first to n-th zones 2-1, 2-2, ..., 2-n of the polar marine structure 1, The first to the n-th zones 2-1, 2-2, ..., 2-n, and so on are different from each other in that the temperature difference occurs in the part where the sunlight is reflected and the part that does not shine, n) because the external environmental conditions are not the same.

In step S730, the fluid circulation control system 400 supplies the fluid heated by the waste heat of the heat generating equipment 300 to the fluid circulation pipe installed in each facility, As shown in FIG.

In step S730, the fluid circulation control system 400 can not only individually or simultaneously control the fluid amount, but also can differentially supply the fluid amount per zone according to the zone heat loss data value.

As described above, in the present embodiment, by constructing the fluid circulation control system 400 that heats the facility where the heat tracing cable is not installed by using the waste heat generated in the heat generator 300 of the polar marine structure 1, It is possible to secure the safety of the operator as well as to prevent the freezing of the icing formed on the equipment or to prevent the icing, and it is unnecessary to additionally install the heat tracing cable in the equipment in which the heat tracing cable is not installed, And the efficiency of operation of the offshore structure can be improved.

In this embodiment, the fluid circulation control is performed so that the amount of fluid supplied to the facility through the fluid circulation pipe can be differently provided for each zone, reflecting the weather information and the actual temperature, wind speed, By constructing the system 400, the limited waste heat can be flexibly operated, thereby widening the installation area of the fluid circulation pipe, thereby improving the reliability of the cooling performance.
