 In short, the FLNG is connected to a flexible pipe connected to the oil well, which is made by drilling in oilfields all over the sea, by means of a device called turret mooring system, The mined oil is classified and extracted as LNG, LPG and condensate through a pretreatment device, a sorting device, and a liquefaction device installed on the top side and then stored in the storage tank of the hull, It is a float-type production facility that can be transported directly to the carrier.

FLNG is very useful as a complex facility for pretreating, liquefying, storing and unloading oil from oil wells for a long period of time at sea, but there is no facilities and functions for drilling.

Therefore, it is difficult to drill a separate drilling rig to a remote well by using a drill ship or a drilling plant, which is costly and time consuming. Especially, in the case where oil is mined in many places where oil reserves are small, such as sail gas, the frequent operation of drill ships causes more cost and time burden.

The classified condensate is stored in the condensate storage tank 106.

The main process module 172 processes the natural gas classified by the pretreatment system 171 to extract a natural gas liquid and classifies the extracted natural gas liquid into condensate and gas again. The classified condensate is stored in the condensate storage tank 106.

The liquefaction module 173 liquefies the gas classified from the main process module 172 to produce LNG and LPG. The produced LNG and LPG are stored in the LNG storage tank 102 and the LPG storage tank 104, respectively.

The FDLPSOU (100) according to the present invention has a propeller at the lower part of the hull (110). The propeller is preferably provided with a stern side propeller 112 and a fore side propeller 114 together.

As a propeller, an azimuth thruster is preferably used to favor weatherbeneing and dynamic positioning. Or a propeller that is equipped with an omnidirectional propulsion unit (eg, a propeller that provides only thrust) in addition to the omnidirectional propulsion unit for weathering and dynamic positioning.

The controller includes a mooring controller 210 for performing weathering in an anchored state by using the turret mooring device 120 and a drilling device 130 for performing drilling in a floating state And a dynamic position controller 220 for performing dynamic positioning control for holding the hull at the target point when the hull is operated.

At the time of weathering, a propeller that is remote from the turret mooring device 120, that is, a stern side propeller 112 is used in the accompanying drawings. However, in some cases, the aft-side propeller 114 may be supplementarily utilized.

The dynamic position control is performed in such a manner that when the drilling is performed while staying in the sea without using the turret mooring device 120 in a large water depth region where normal mooring is difficult, the stern side propeller 112 and the aft side propeller 112 Side propeller 114 in combination. At this time, a position detection system using a radio wave, an ultrasonic wave, a GPS (Global Positioning System), a navigation device, and the like, and a load sensor, a radar, a wind direction sensor, The displacement is detected based on the environmental information, and the driving of the propeller (112, 114) is appropriately combined to control the hull so as not to deviate from a predetermined coordinate.

The dynamic position control can also be used to perform drilling in conjunction with drilling or in conjunction with drilling to produce LNG using the turret mooring device 120, The stern side propeller 112 and the forward side propeller 114 are driven in combination when the hull is to be maintained in the drilling target area.

1 to 3, the FDLPSOU 100 according to the present invention includes a flare tower 140 for burning a decompressed gas generated in a drilling or production process on an upper deck 110b Respectively. There is also a Living Quarter (150) for the crew to reside in.

The FDLPSOU 100 according to the present invention realizes a new concept of a floating structure that can produce LNG simultaneously with a drilling operation. In other words, it is a marine structure that can produce, store and unload LNG through liquefied gas production process from gas oil extracted from submarine oil well constructed by drilling in underwater oil field.

The FDLPSOU (100) according to the present invention can be used to perform an underwater drilling operation, to perform production, storage and unloading of LNG from crude oil extracted from oil wells, or to perform drilling and LNG production operations in parallel .

During the subsea drilling operation, the drilling string 136 is drilled down through the drilling device 130 while maintaining the target position for drilling through the dynamic position controller 220 and the propellers 112 and 114. When the drilling is completed, a material such as a BOP (Blow Out Preventer) is lowered through the door pool 132 to construct a well. The mud mixture drawn in the drilling process is sent to the mud processing module 174. The gas oil crude oil extracted from the mud processing module 174 is transferred to the pretreatment system 171 of the liquefied gas production process facility.

In the submarine drilling operation, it is possible to perform an anchoring operation using the turret mooring device 120. In this case, dynamic visibility control is performed through the dynamic location controller 220 instead of performing weather blinding.

The LNG production operation anchors the mooring line 126 to the seafloor via the turret mooring device 120 at approximately the midpoint of the wells formed or formed at various points on the seabed by drilling. In addition, weatherbeneing is performed through the mooring controller 210 and the propeller 112 or the propeller 112, 114.

In the LNG production operation, the turret mooring apparatus 120 may be used to perform dynamic position control through the dynamic position controller 220 without anchoring.

In the LNG production operation, a flexible mining pipe 128 is connected to the wells from the buoy at the bottom of the turret to extract the crude oil from the gas oil. The extracted gas oil crude oil is extracted, sorted and liquefied through a pretreatment system 171, a main process module 172 and a liquefaction module 173 installed in the deck upper part 110b to produce LNG, LPG and condensate. The produced LNG, LPG, and condensate are separately stored in the storage tanks 102, 104, and 106.

When the submarine drilling operation and the LNG production operation are performed concurrently, it is possible to carry out the dynamic position control while performing the dynamic position control with the turret mooring device 120 being anchored, or performing the dynamic position control without the anchoring operation.

The dynamic position control in the anchored state via the turret mooring device 120 may be performed by using only the stern side propeller 112 or by using both the stern side propeller 112 and the forward side propeller 114 to rotate the turret 122 Adjust the hull to be centered within the target area.

The LNG, LPG, and condensate stored in the storage tanks 102, 104, and 106 can be discharged to the FDLPSOU 100 according to the present invention by using the cargo handling facility 180 in a state of lateral mooring or ending mooring Move it.
