Definitions
- the present invention relates to a floating type structure.
- Liquefied natural gas is a colorless transparent liquid obtained by cooling and liquefying natural gas (NG), which contains methane as a main component, at about -162 °C. LNG has a volume which is about 1/600 that of NG.
- NG when NG is liquefied into LNG, NG may be transported efficiently.
- an LNG carrier which can transport (carry) LNG by sea is used.
- LNG FPSO LNG floating, production, storage, and offloading
- the LNG FPSO is moored at a specific point in the sea, collects NG from a gas well of the ocean bed, liquefies the collected NG, and then stores the LNG in a storage tank.
- the LNG stored in the LNG FPSO may be moved to the LNG carrier and transported to a destination.
- the LNG stored in the LNG FPSO is moved to the LNG carrier in a state in which the LNG carrier is moored to the LNG FPSO.
- a loading arm may be installed on the LNG FPSO, a manifold corresponding to the loading arm may be installed on the LNG carrier, and the loading arm may be connected to the manifold to transfer the LNG to the LNG carrier.
- the transferring of the LNG is carried out in a state in which both of the LNG FPSO and the LNG carrier are floating on the sea.
- the LNG FPSO and the LNG carrier move independently according to sea conditions such as winds, waves, and the like. That is, the LNG FPSO and the LNG carrier exhibit different motion responses according to a surrounding environment such that excessive vertical relative movements occur. Consequently, it is very difficult to connect the loading arm of the LNG FPSO to the manifold of the LNG carrier, and there is a problem in that an impact is applied to a connected portion, or a coupling therebetween is loosed.

Description
- The present invention relates to a floating type structure.
- Liquefied natural gas (LNG) is a colorless transparent liquid obtained by cooling and liquefying natural gas (NG), which contains methane as a main component, at about -162 °C. LNG has a volume which is about 1/600 that of NG.
- Therefore, when NG is liquefied into LNG, NG may be transported efficiently. For example, an LNG carrier which can transport (carry) LNG by sea is used.
- Recently, an LNG floating, production, storage, and offloading (LNG FPSO) unit has been used to collect, liquefy, and store NG at sea.
- The LNG FPSO is moored at a specific point in the sea, collects NG from a gas well of the ocean bed, liquefies the collected NG, and then stores the LNG in a storage tank. The LNG stored in the LNG FPSO may be moved to the LNG carrier and transported to a destination.
- In this case, the LNG stored in the LNG FPSO is moved to the LNG carrier in a state in which the LNG carrier is moored to the LNG FPSO. To this end, a loading arm may be installed on the LNG FPSO, a manifold corresponding to the loading arm may be installed on the LNG carrier, and the loading arm may be connected to the manifold to transfer the LNG to the LNG carrier.
- However, the transferring of the LNG is carried out in a state in which both of the LNG FPSO and the LNG carrier are floating on the sea. In this case, the LNG FPSO and the LNG carrier move independently according to sea conditions such as winds, waves, and the like. That is, the LNG FPSO and the LNG carrier exhibit different motion responses according to a surrounding environment such that excessive vertical relative movements occur. Consequently, it is very difficult to connect the loading arm of the LNG FPSO to the manifold of the LNG carrier, and there is a problem in that an impact is applied to a connected portion, or a coupling therebetween is loosed.

FIG. 1 , a floatingtype structure 100 according to one embodiment of the present invention includes ahull 10, aloading arm 110, a loading arm ascending and descending device E, and a fluid storage tank (not shown). - For example, the floating
type structure 100 may be a floating production storage offloading (FPSO) which produces and stores crude oil. However, the technical spirit of the present invention is not limited thereto. - The floating
type structure 100 may provide a fluid, e.g., a liquefied natural gas (LNG), stored in a fluid storage tank (not shown) disposed inside thehull 10 to a carrier 1 through theloading arm 110. However, the technical spirit of the present invention is not limited thereto. - In this case, the
loading arm 110 may be connected to amanifold 2 installed on the carrier 1 to provide the fluid to the carrier 1. - Specifically, the
loading arm 110 may be configured with a plurality of arms which are connected to be bendable such that theloading arm 110 may extend in a direction in which the carrier 1 is disposed. Theloading arm 110 may be fixedly installed on the loading arm ascending and descending device E which is installed on thehull 10.

plunger base 130 may include thesecond connector 131 having a U-shaped groove coupled to a second end opposite the first end of thecylinder 140. Theplunger base 130 may be easily attached to and detached from the second end of thecylinder 140 using the U-shaped groove formed in thesecond connector 131. - The
cylinder 140 may connect theplunger 120 to theplunger base 130. Specifically, the first end of thecylinder 140 may be coupled to thefirst connector 121 installed on theplunger 120, and the second end of thecylinder 140 may be coupled to thesecond connector 131 installed on theplunger base 130. - For example, the
cylinder 140 may ascend or descend theplunger 120 using a hydraulic pressure. However, the technical spirit of the present invention is not limited thereto. That is, in some other embodiments, thecylinder 140 may be driven using a mechanical device, e.g., a motor. - The
cylinder 140 may ascend or descend theplunger 120 to thereby ascend or descend theloading arm 110 connected to theplunger 120. Consequently, the floatingtype structure 100 may adjust the height of theloading arm 110 from the upper surface of thehull 10 using thecylinder 140. - The
connection pipe 170 may be connected to thepipe 40 installed on thehull 10 and allow a height from thehull 10 to be adjustable. - Specifically, the
connection pipe 170 may include afirst connection pipe 171 connected to thepipe 40 and asecond connection pipe 172 for connecting thefirst connection pipe 171 to theloading arm 110. However, the technical spirit of the present invention is not limited thereto. That is, in some other embodiments, theconnection pipe 170 may include three or more connection pipes. - The
first connection pipe 171 may be connected to thepipe 40 by the first joint 173 and rotated around thepipe 40. Thesecond connection pipe 172 may be connected to thefirst connection pipe 171 by the second joint 174 and rotated around thefirst connection pipe 171. Thesecond connection pipe 172 may be connected to theloading arm 110 by the third joint 175 and rotated about theloading arm 110. - Even when the
loading arm 110 is ascended from the upper surface of thehull 10, thefirst connection pipe 171 and thesecond connection pipe 172 may maintain a connection between theloading arm 110 and thepipe 40 using the first, second, andthird joints first connection pipe 171 and thesecond connection pipe 172 may each have a C shape, and one end of thefirst connection pipe 171 may be connected to one end of thesecond connection pipe 172 through thesecond joint 174. - The above operations of the
first connection pipe 171 and thesecond connection pipe 172 are shown inFIGS. 5 and6 . -
FIG. 5 illustrates a state in which theplunger 120 is inserted into theplunger base 130 and thus theloading arm 110 is disposed adjacent to the upper surface of thehull 10. In this case, the first andsecond connection pipes pipe 40. - As shown in
FIG. 6 , thecylinder 140 is operated to ascend theplunger 120 such that theloading arm 110 is ascended from the upper surface of thehull 10. - In this case, the
first connection pipe 171 may be rotated around the first andsecond joints second connection pipe 172 may be rotated around the second andthird joints - Consequently, the
connection pipe 170 may maintain the connection between theloading arm 110 and thepipe 40. - As shown in
FIG. 3 , theconnection pipe 170 and the first, second, andthird joints recess 20 formed in thehull 10. - Consequently, even though the
loading arm 110 is ascended or descended, theconnection pipe 170 may maintain the connection between theloading arm 110 and thepipe 40 without interference of the upper surface of thehull 10. - Referring to
FIGS. 2 and7 , thecylinder cover 150 includes a first region R1 in which anopening 151 is formed and a second region R2 in which theopening 151 is not formed. - In this case, the second region R2 may include an area that is equal to an area of the
opening 151. Thus, as described below, when the coupling of thecylinder 140 is released, thecylinder 140 may be moved to theconnection groove 30 ofFIG. 10 into which the second region R2 of thecylinder cover 150 is inserted. - The
cylinder cover 150 may be connected to thecylinder 140 through theopening 151. Specifically, thecylinder cover 150 may surround a side surface of thecylinder 140 which is installed to pass through theopening 151, thereby being connected to thecylinder 140. - The
cylinder cover 150 may be inserted into theconnection groove 30 ofFIG. 10 formed in a lower surface of therecess 20, which is formed in thehull 10, thereby being coupled to therecess 20. Consequently, thecylinder cover 150 may couple thecylinder 140 to theconnection groove 30 ofFIG. 10 formed in therecess 20. - Referring to
FIG. 7 , the cylinder packing 160 may be disposed on thecylinder cover 150. The cylinder packing 160 may surround a side surface of thecylinder 140 to block seawater from being introduced into thehull 10 through a minute space between thecylinder cover 150 and thecylinder 140. - Hereinafter, coupling and release operations of a cylinder in the floating type structure according to one embodiment of the present invention will be described with reference to
FIGS. 7 to 11 . -
FIGS. 8 to 11 are diagrams for describing coupling and release operations of the cylinder. - Referring to
FIGS. 8 and9 first, when the coupling of thecylinder 140 is released, theplunger 120 is descended to a lowest position. - Then, the first end of the
cylinder 140 coupled to thefirst connector 121 of theplunger 120 is descended to release the coupling between thefirst connector 121 and the first end of thecylinder 140. In this case, as described above, since thefirst connector 121 has a U shape, thefirst connector 121 may be easily released from the first end of thecylinder 140. - Referring to
FIGS. 9 and10 , thecylinder cover 150 is ascended from theconnection groove 30, which is formed in the lower surface of therecess 20 formed in thehull 10 so that the coupling of thecylinder cover 150 to theconnection groove 30 is released. - Referring to
FIGS. 7 ,10 , and11 , thecylinder 140 is pivoted around thesecond connector 131 of theplunger base 130. - Specifically, the
cylinder 140 is pivoted from one side of theconnection groove 30 into which the first region R1 of thecylinder cover 150 is inserted to the other side of theconnection groove 30 into which the second region R2 of thecylinder cover 150 is inserted. - In this case, as shown in
FIG. 3 , in order to avoid interference between thecylinder cover 150 being moved and a side wall of therecess 20, theconnection groove 30 is formed to be spaced apart from the side wall of therecess 20. - Then, the second end of the
cylinder 140 coupled to thesecond connector 131 of theplunger base 130 is ascended to release the coupling between thesecond connector 131 and the second end of thecylinder 140. - In this case, as described above, since the
second connector 131 has a U shape, thesecond connector 131 may be easily released from the second end of thecylinder 140. - The above-described operations may be performed to release the couplings between the
cylinder 140 and theplunger 120 and between thecylinder 140 and theplunger base 130. Further, the above-described operations may be performed reversely to couple thecylinder 140 to theplunger 120 and theplunger base 130. - The floating
type structure 100 according to the first example may maintain the connection of theloading arm 110 while compensating for the height difference between the carrier 1 and the floatingtype structure 100 using the loading arm ascending and descending device E and theconnection pipe 170. - Further, the floating
type structure 100 according to the first example is capable of facilitating maintenance and repair of thecylinder 140 by releasing the coupling of thecylinder 140 using thecylinder cover 150. - Hereinafter, an internal structure and an operation of a floating type structure according to the present invention will be described with reference to

plunger 420 is connected to theloading arm 410 disposed on thehull 310. Specifically, an upper surface of theplunger 420 may be connected to theloading arm 410, and theplunger 420 may be inserted into theplunger base 430. Theplunger 420 is coupled to a first end of thecylinder 440. - The
plunger base 430 is disposed in thehull 310. Specifically, theplunger base 430 is connected to thefirst recess 320 formed in thehull 310, and theplunger 420 is inserted into theplunger base 430. Theplunger base 430 is coupled to a second end of thecylinder 440 opposite the first end thereof. - Referring to
FIG. 16 , theplunger base 430 includes thepressure adjusting hole 431 formed therebelow. - When the
plunger 420 is descended in a direction of sea level inside theplunger base 430, theplunger base 430 allows air thereinside to flow out through thepressure adjusting hole 431 along thesecond drain pipe 480 connected to thepressure adjusting hole 431, thereby adjusting an inner pressure of theplunger base 430. - Further, when the
plunger 420 is ascended from inside theplunger base 430 toward a position of an upper surface of thehull 310, theplunger base 430 allows external air to be introduced through thepressure adjusting hole 431 along thesecond drain pipe 480 connected to thepressure adjusting hole 431, thereby adjusting the inner pressure of theplunger base 430. - The
cylinder 440 connects theplunger 420 to theplunger base 430. - Specifically, the first end of the
cylinder 440 may be coupled to theplunger 420, and the second end of thecylinder 440 are coupled to theplunger base 430. - For example, the
cylinder 440 may ascend or descend theplunger 420 using a hydraulic pressure. However, in some other embodiments, thecylinder 440 may be driven using a mechanical device, e.g., a motor. - The
cylinder 440 may ascend or descend theplunger 420 and theloading arm 410 connected to theplunger 420. Consequently, the floating type structure 400 may adjust the height of theloading arm 410 from the upper surface of thehull 310 using thecylinder 440. - The
drain 450 may be formed on a lower surface of thefirst recess 320 which is formed in thehull 310. A plurality ofdrains 450 may be formed on the lower surface of thefirst recess 320. - As shown in
FIG. 13 , the plurality ofdrains 450 may each be formed at an edge of thefirst recess 320 which does not overlap theplunger base 430 connected to thefirst recess 320. - The
drains 450 may discharge a fluid, e.g., rainwater or seawater, which is accumulated in thefirst recess 320 and thesecond recess 330 adjacent thereto, along thefirst drain pipe 460 connected to each of thedrains 450. - Referring to
FIG. 14 , a lower surface of thesecond recess 330 is formed to be closer to the upper surface of thehull 310 than the lower surface of thefirst recess 320. - Specifically, a second height h2 from the lower surface of the
second recess 330 to the upper surface of thehull 310 may be smaller than a first height h1 from the lower surface of thefirst recess 320 to the upper surface of thehull 310. - Consequently, even when a separate drain is not installed in the
second recess 330, the fluid accumulated in the first andsecond recesses drains 450 formed in thefirst recess 320. - However, in some other embodiments, the
drains 450 may also be formed in thesecond recess 330. Further, in some other embodiments, thedrains 450 may be formed in only thesecond recess 330, and the second height h2 from the lower surface of thesecond recess 330 to the upper surface of thehull 310 may be greater than the first height h1 from the lower surface of thefirst recess 320 to the upper surface of thehull 310. - Referring to
FIGS. 14 to 16 , thefirst drain pipe 460 between each of thedrains 450 and thesecond drain pipe 480. Thefirst drain pipe 460 may discharge a fluid, e.g., rainwater or seawater, which is introduced through thedrains 450, by providing the fluid to thesecond drain pipe 480. - One end of the
second drain pipe 480 is connected to thepressure adjusting hole 431 formed at a lower portion of theplunger base 430, and thefirst drain pipe 460 may be connected to a side surface ofsecond drain pipe 480. - The
second drain pipe 480 allows air to flow in and out theplunger base 430 according to an inner pressure of theplunger base 430. - The
second drain pipe 480 simplifies a drain pipe configuration inside thehull 310 by performing a function of discharging the fluid introduced through thefirst drain pipe 460 and flowing in thesecond drain pipe 480 and a function of adjusting the inner pressure of theplunger base 430. - The
connection pipe 470 is disposed on thesecond recess 320. Theconnection pipe 470 may be connected to thepipe 340 installed on thehull 310 and allows a height from thehull 310 to be adjustable. - Specifically, the
connection pipe 470 may include afirst connection pipe 471 connected to thepipe 340, and asecond connection pipe 472 for connecting thefirst connection pipe 471 to theloading arm 410. However, the technical spirit of the present invention is not limited thereto. That is, in some other embodiments, theconnection pipe 470 may include three or more connection pipes. - The
first connection pipe 471 may be connected to thepipe 340 by the first joint 473 and rotated around thepipe 340. Thesecond connection pipe 472 may be connected to thefirst connection pipe 471 by the second joint 474 and rotated around thefirst connection pipe 471. Thesecond connection pipe 472 may be connected to theloading arm 410 by the third joint 475 and rotated about theloading arm 410. - Even when the
loading arm 410 is ascended from the upper surface of thehull 310, thefirst connection pipe 471 and thesecond connection pipe 472 may maintain a connection between theloading arm 410 and thepipe 340 using the first, second, andthird joints first connection pipe 471 and thesecond connection pipe 472 may each have a C shape, and one end of thefirst connection pipe 471 may be connected to one end of thesecond connection pipe 472 through thesecond joint 474. - The above operations of the
first connection pipe 471 and thesecond connection pipe 472 are shown inFIGS. 18 and19 which will be described below. - Although not shown in the drawings, lines (e.g., electric lines, hydraulic pressure supply lines, nitrogen lines, and the like) may be installed along the
pipe 340 and theconnection pipe 470. - Hereinafter, an operation of a connection pipe according to an ascending or descending operation of a loading arm ascending and descending device of the floating type structure according to another example will be described with reference to
FIGS. 18 and19 . -
FIGS. 18 and19 are diagrams for describing an operation of a connection pipe according to an operation of the loading arm ascending and descending device of the floating type structure. -
FIG. 18 illustrates a state in which theplunger 420 is inserted into theplunger base 430 and thus theloading arm 410 is disposed adjacent to the upper surface of thehull 310. In this case, the first andsecond connection pipes pipe 340. - As shown in
FIG. 19 , thecylinder 440 is operated to ascend theplunger 420 such that theloading arm 410 is ascended from the upper surface of thehull 310. - In this case, the
first connection pipe 471 may be rotated around the first andsecond joints second connection pipe 472 may be rotated around the second andthird joints - Consequently, the
connection pipe 470 may maintain the connection between theloading arm 410 and thepipe 340. - As shown in
FIG. 13 , theconnection pipe 470 and the first, second, andthird joints second recess 330 formed in thehull 310. - Consequently, even though the
loading arm 410 is ascended or descended, theconnection pipe 470 may maintain the connection between theloading arm 410 and thepipe 340 without interference of the upper surface of thehull 310. - The floating type structure 400 according to another example may maintain the connection of the
loading arm 410 while compensating for the height difference between the carrier 1 and the floating type structure 400 using the loading arm ascending and descending device E and theconnection pipe 470. - Further, the floating type structure 400 according to another example may simplify the drain pipe configuration inside the
hull 310 by performing a function of discharging the fluid accumulated in the first andsecond recesses hull 310 and a function of adjusting the inner pressure of theplunger base 430 using thesecond drain pipe 480 connected to thefirst drain pipe 460. - While the present invention has been described with reference to the accompanying drawings, those skilled in the art can understand that the present invention can be implemented in other specific forms.
