Floater system connected with floating production storage and offloading (FPSO) boat body

Abstract

The invention discloses a floater system connected with a floating production storage and offloading (FPSO) boat body, which comprises the floater, an anchoring chain and a vertical tube, wherein the anchoring chain and the vertical tube are connected to the floater; the floater comprises a cone part and a pedestal; the lower bottom face of the cone part is fixed on the pedestal; a permanent buoyancy chamber and a draining chamber are arranged in the floater; a draining outlet which can be opened and closed is formed at the bottom of the draining chamber; a vent communicated with the draining chamber is formed at the top of the floater; and the vent is connected with an air compressor through an air intake pipe when the floater floats upwards to let air in and is connected with a floater floating on water surface through the air intake pipe when the floater sinks to exhaust. When the draining chamber is filled with air, the floater floats upwards; and when water enters the draining chamber, the floater sinks, so the control on ascending and descending of the floater is easier to realize. Because the surface of the cone part is the combination of a conical face and a polygonal plane, when the floater is connected with the FPSO boat body, quick positioning and rotation prevention can be realized by means of the polygonal plane, the cone part is locked, and then the floater and the FPSO boat body are more convenient and quicker to connect.

Description

technical field [0001] The invention relates to the field of marine oil and gas equipment, in particular to a buoy system that can be connected with an FPSO hull. Background technique [0002] FPSO (Floating production, storage, offloading unit) floating production storage and offloading ship has the functions of production, oil storage and oil offloading, and is one of the main modes of offshore oil development. At present, with the substantial increase in the consumption of oil and gas resources in my country, the country's demand for oil and gas resources is also increasing. Effective, economical and rapid development of my country's South China Sea resources is imminent. Due to the relatively hostile environment in the South China Sea, the traditional permanent mooring method can no longer adapt to the natural environment of the South China Sea. The new type of detachable mooring method is the development trend, from passive bearing to active prevention. The traditional...

Problems solved by technology

Due to the relatively hostile environment in the South China Sea, the traditional permanent mooring method can no longer adapt to the natural environment of the South China Sea. The new type of mooring method that can be released is the development trend, from passive bearing to active prevention

The traditional detachable FPSO adopts the form of turret, RTM (Riser Turrent Mooring) and BTM (Buoycant Turrent Mooring). The disadvantages of this turret are: the scale is relatively small, the system is relatively complicated, the manufacturing cost is high, and the price is extremely expensive. Moreover, the number and form of risers are limited

The float system disclosed in this patent application can realize the connection and release between the float and the hull relatively conveniently. Relative rotation for easy locking operation, how to more conveniently control the floating and sinking of the float still needs to be further improved
