Buoy release and recovery system based on separable inner turret mooring system

Abstract

The invention relates to a buoy releasing and retracting system based on a separable inner turret mooring system. The buoy releasing and retracting system comprises a buoy, a barrier frame device anda clamping device, wherein the buoy comprises an outermost anti-rolling tank, a water ballast tank located inside the anti-rolling tank and a sealed cabin located inside the water ballast tank, the middle part of the buoy penetrates through liquid transfer piping, and the separation part of the liquid transfer piping is arranged in the sealed cabin; the barrier frame device includes a barrier frame and a barrier frame storage groove, and the barrier frame can be unfolded or folded; and the clamping device includes a position controlling frame, a clamping arm, a contraction chain and a power contraction device, and the clamping device is installed in a turret to cooperate with the barrier frame to assist releasing and retracting of the buoy. According to the buoy releasing and retracting system based on the separable inner turret mooring system, better sealing conditions are provided for the separation of the piping by arranging the sealed cabin, efficient releasing and retracting of the buoy can be realized by arranging the matching barrier frame device and clamping device, so that the releasing and retracting process of the buoy is efficient and simple, the process is safer and more reliable, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of internal turret mooring systems, in particular to a buoy release and recovery system that assists the separation and docking of the turret mooring system. Background technique [0002] The internal turret mooring system is a single-point mooring system that can improve the impact of environmental loads on floating platforms or hulls. It is widely used in many offshore floating bodies, especially large oil production and storage ships. It is arranged in a It vertically runs through the moon pool of the hull. [0003] Floating Drilling, Production, Storage and Offloading Ship (FDPSO) is a highly integrated energy development ship that integrates the functions of drilling, production, well workover, well completion, oil storage and offloading, etc. It can reduce investment costs and shorten production cycles. Since the last century After it was proposed in the 1990s, it has attracted widespread attention in...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the valve-type separation method existing in the above-mentioned prior art cannot timely seal the separated liquid transmission piping system, the difficulty in the cable traction and recovery process and the large free drift of the buoy without the anti-rolling water tank on the sea surface cause Violent shaking, collision with the hull, resulting in pipeline rupture and liquid leakage, etc., a buoy release and recovery system based on a separable inner turret mooring system is provided, which can be installed in the buoy through the sealed cabin Provide better sealing conditions for the separation of the piping system. By setting the supporting barrier device and clamping device, the efficient release and recovery of the buoy can be realized, which makes the process of buoy release and recovery efficient and simple, making the process safer and more reliable. Save manpower and material resources, and improve the production efficiency of production oil production ships
