Problems solved by technology

[0010] The locking between the float and the hull of APL is realized by the bearing system between the top of the float and the bottom of the float, so the locking device can only provide vertical constraints for the float, and cannot control its own rotation around the vertical direction.

Embodiment Construction

[0032] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0033] Such as figure 1 As shown, the present embodiment comprises: hull 1, buoy 2, mooring rope 3 and riser 4, wherein: buoy 2 is socketed inside hull 1, and the two ends of several mooring ropes 3 are connected with the bottom big diameter of buoy 2 respectively. The edge of the base of the disk is connected to the anchor point on the seabed, and the lower ends of several risers 4 are connected to the oil production point on the seabed.

[0034] The buoyancy force received by the buoy 2 plus the buoyancy force received by the hull 1 is balanced with the weight of the buoy 2 and the hull 1 and the downward pullin...

Abstract

The invention discloses a circular floating ocean platform capable of releasing multi-point mooring in the technical field of ocean oil-gas engineering and ships. The circular floating ocean platform comprises a ship body, a floater, a mooring cable and stand pipes, wherein the floater is sleeved to the interior of the ship body, the top of the floater is positioned above the surface of water, and two ends of the mooring cable are connected with the bottom of the floater and a seabed mooring point respectively; and if the lower ends of a plurality of the stand pipes are connected with underwater oil-gas production facilities at the seabed, the upper ends of the stand pipes are communicated to the top of the floater through the bottom of the floater, and connected to an interface on the top of the floater. The ship body has a circular structure, and the center of the ship body is provided with a hollow circular cavity for fixing the floater. The circular floating ocean platform works under severe sea conditions, is released in advance before heavy storm or iceberg or other severe sea conditions to drag a production oil storage and unloading platform ship body to a safe sea area to ensure safety, and is reconnected to recover normal production work after the severe environments.

Description

technical field [0001] The invention relates to a device in the field of marine oil and gas engineering and ship technology, in particular to a detachable multi-point mooring ring-shaped floating offshore platform. Background technique [0002] The demand for energy in modern industry is increasing day by day, and oil and gas resources play an important role in the existing energy. At present, the general trend of oil and gas development is from land to sea, and offshore oil and gas development is from shallow sea to deep sea. The sea area of ​​oil and gas exploitation gradually extends from the mild environment to the sea area with harsh sea conditions. [0003] FPSO (Floating production, storage, offloading unit) is one of the main modes of offshore oil development, and is widely used in oil and gas production, storage and export in various sea areas around the world. The traditional production storage and unloading platform is developed from an oil tanker with a ship-sh...
