Technical Field

The invention relates to the technical field of cylinder FPSO (Floating production storage and offloading) berthing, in particular to a method for berthing a cylinder FPSO on a wharf.

Background

The FPSO is a floating production oil storage and discharge device, is a comprehensive large offshore oil production device which is used for carrying out oil-gas separation on the exploited oil, treating oily sewage, generating power, supplying heat and storing and transporting crude oil products, and integrates the living of workers and a production command system.

The FPSO can be divided into different types of FPSOs according to the shape, wherein the cylinder-type FPSO is a commonly used FPSO, and the cylinder-type FPSO is easily damaged due to the fact that the designated orientation of the cylinder-type FPSO cannot be accurately anchored on a ship-anchoring member on a wharf due to the shape limitation during anchoring.

Therefore, a method for a quay mooring drum type FPSO is urgently needed to solve the above problems.

In order to solve the above technical problems, the present invention provides a method for a quay mooring cylindrical FPSO, including step S1 of uniformly arranging at least three tugs on a circumferential wall of the cylindrical FPSO; s2, rotating the cylindrical FPSO to a specified orientation through at least three tugs; s3, the tug close to the designated direction is released, and the boat leaning piece is moved to the peripheral wall of the cylindrical FPSO by the released tug for installation; and S4, moving the cylinder type FPSO provided with the ship-leaning piece to the wharf through a winch arranged on the wharf, and controlling the orientation of the ship-leaning piece through the tug on the peripheral wall of the cylinder type FPSO when the cylinder type FPSO moves until the ship-leaning piece is close to the wharf.

In step S1, the number of the tugs is four, and the four tugs are respectively a first tug, a second tug, a third tug and a fourth tug.

Further, the step S1 specifically includes: connecting the first tug, the third tug and the fourth tug to the peripheral wall of the cylindrical FPSO respectively; moving the cylinder type FPSO to a designated water area through the first tug, the third tug and the fourth tug; and after the cylinder-type FPSO is moved to the specified water area, connecting the second tug to the peripheral wall of the cylinder-type FPSO, and adjusting the positions of the first tug, the second tug, the third tug and the fourth tug until the first tug, the second tug, the third tug and the fourth tug are uniformly arranged on the peripheral wall of the cylinder-type FPSO.

Further, the step S2 specifically includes: rotating the drum-type FPSO to a specified orientation by the first tug, the second tug, the third tug, and the fourth tug.

Further, the step S3 specifically includes: and releasing the third tug close to the designated orientation, then installing the third tug on the boat holding member, and finally moving the boat holding member to the peripheral wall of the cylindrical FPSO through the third tug for installation.

Further, the step S4 specifically includes: the winch is arranged on the edge of the wharf and is connected with the barrel-shaped FPSO through a steel wire rope on the winch; the winch drives the steel wire rope to drive the cylindrical FPSO provided with the ship leaning piece to move towards the wharf, and the first tug, the second tug and the fourth tug are used for controlling the ship leaning piece on the cylindrical FPSO to be aligned with the wharf when the cylindrical FPSO moves until the ship leaning piece abuts against the wharf.

The invention has the technical effects that: at least three tugs are uniformly arranged on the peripheral wall of the cylinder type FPSO; rotating the drum-type FPSO to a specified orientation by at least three of the tugs; removing the tug close to the designated orientation, and moving the ship leaning piece to the peripheral wall of the cylindrical FPSO through the removed tug for installation; and moving the cylinder-type FPSO provided with the ship-alongside member to the wharf by a winch arranged on the wharf, wherein the cylinder-type FPSO controls the orientation of the ship-alongside member by the tug wheels on the peripheral wall of the cylinder-type FPSO until the ship-alongside member is close to the wharf. Therefore, the cylindrical FPSO can be close to the wharf through the ship leaning piece in the designated direction, and the condition that the cylindrical FPSO is damaged by collision due to the fact that the ship leaning piece in the designated direction can not be accurately leaned on the wharf when the cylindrical FPSO is leaned on the wharf is avoided.

The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.

An embodiment of the present invention provides a method for a quay mooring cylindrical FPSO, which is shown in fig. 1 to 7 and includes the following steps.

S1, at least three tugs are evenly arranged on the peripheral wall of the cylinder type FPSO 1.

S2, rotating the cylinder type FPSO1 to a designated orientation through at least three tugs.

S3, the tug approaching the designated orientation is released, and the boat 6 is moved to the peripheral wall of the cylindrical FPSO1 by the released tug and mounted.

S4, the cylinder type FPSO1 with the boat 6 mounted thereon is moved to the quay 7 by the winch 8 mounted on the quay 7, and the cylinder type FPSO1 controls the orientation of the boat 6 by the tug on the peripheral wall thereof until the boat 6 abuts on the quay 7 when moving.

The embodiment is realized by uniformly arranging at least three tugs on the peripheral wall of the cylinder type FPSO 1; rotating the drum-type FPSO1 to a specified orientation by at least three of the tugs; removing the tug near the designated orientation, and moving the boat 6 to the peripheral wall of the cylindrical FPSO1 by the removed tug; the cylinder type FPSO1 with the boat-holding member 6 mounted thereon is moved to the quay 7 by a winch 8 mounted on the quay 7, and the cylinder type FPSO1 controls the orientation of the boat-holding member 6 by the tug on the peripheral wall thereof until the boat-holding member 6 abuts on the quay 7 when moving. Therefore, the cylinder-type FPSO1 can be close to the wharf 7 through the ship-leaning device 6 in the designated direction, and the situation that the cylinder-type FPSO1 is damaged due to the fact that the ship-leaning device 6 in the designated direction cannot be accurately berthed on the wharf 7 when the cylinder-type FPSO1 is berthed is avoided.

In step S1 of this embodiment, the number of the tugs is four, and the four tugs are the first tug 2, the second tug 3, the third tug 4 and the fourth tug 5, respectively.

In step S1 of this embodiment, the first tug 2, the third tug 4 and the fourth tug 5 are connected to the peripheral wall of the cylinder-type FPSO 1.

Then, the cylinder type FPSO1 is moved to a designated water area by the first tug 2, the third tug 4 and the fourth tug 5.

Finally, after the cylinder-type FPSO1 is moved to the specified water area, the second tug 3 is connected to the circumferential wall of the cylinder-type FPSO1, and the positions of the first tug 2, the second tug 3, the third tug 4 and the fourth tug 5 are adjusted until the first tug 2, the second tug 3, the third tug 4 and the fourth tug 5 are uniformly arranged on the circumferential wall of the cylinder-type FPSO 1.

In step S2 of the present embodiment, the cylinder FPSO1 is rotated to a predetermined orientation by the first tug 2, the second tug 3, the third tug 4 and the fourth tug 5.

In step S3 of this embodiment, the third tug 4 near the designated orientation is released, the third tug 4 is then mounted on the boat holding member 6, and the boat holding member 6 is finally moved to the peripheral wall of the cylindrical FPSO1 by the third tug 4 and mounted.

In step S4 of this embodiment, the winch 8 is first installed at the edge of the dock 7 and connected to the barrel-type FPSO1 through a wire rope on the winch 8; then the winch 8 drives the steel wire rope to drive the cylinder-type FPSO1 provided with the boat-holding piece 6 to move towards the wharf 7, and the cylinder-type FPSO1 controls the boat-holding piece 6 on the cylinder-type FPSO1 to be aligned with the wharf 7 through the first tug 2, the second tug 3 and the fourth tug 5 when moving until the boat-holding piece 6 abuts against the wharf 7.
