Description
Technical Field
The present invention relates to a mooring system, and more particularly to a single point mooring system with a quick retraction mechanism for a soft rigid arm.
Background
In shallow sea oil and gas development, particularly in marginal fields, offshore floating units are favored because of their mobility. In Bohai sea, the cooperation of the floating production device on the sea and the operation platform group is an important mode of oil and gas exploitation, and the floating production device is limited in the oil and gas exploitation sea area through a mooring system. The electric power and fresh water required by oil gas exploitation are transmitted to the platform by the offshore floating production device through cables and hoses, and the oil gas exploited by the operation platform is transmitted to the floating production device through the hoses for processing.
When an offshore floating unit encounters extreme sea conditions or encounters an emergency, it is required to rapidly disconnect from the mooring system and travel away from the sea area to avoid serious safety accidents. The separation process of the offshore floating device and the mooring system comprises the operations of pulling, dismantling and fixing the bridging hose and the bridging cable, pulling and hanging the mooring cable, separating and fixing the mooring legs and the YOKE arms, limiting the offshore floating device and the like.
The towing, dismantling and fixing of the bridging hose and the bridging cable needs operations such as rope tying, releasing, towing, hanging and fixing, and the like, and has complex process and long time consumption. Meanwhile, good weather is required to be selected for releasing, and when releasing is carried out, the floating production device and the single-point system are always connected, so that the emergency strain capacity is insufficient.
Specifically, when the offshore floating device is separated from the mooring system, the jumper hose, the jumper cable and the like are detached and then erected on the offshore floating device, and the jumper hose and the jumper cable can be completely sailed after being completely stored on the offshore floating device, so that the separation speed is greatly reduced.

In order to achieve the above purpose, the invention adopts the following technical scheme:
A soft rigid arm single point mooring system with a rapid cable retracting device comprises an operation platform foundation serving as a base, wherein a hose deck is arranged on the operation platform foundation, and an operation platform is arranged on the hose deck; the side surface of the hose deck is connected with two soft steel arm ballast tanks for connecting a mooring ship, a horizontal cross brace is connected between the two soft steel arm ballast tanks, and a supporting structure higher than the cross brace is connected on the cross brace; the support structure is provided with a rotatable first rubber roller; the operation platform is provided with a first winch, and the first winch is connected to the supporting structure through a first cable;
The operation platform is also provided with a second winch, and a second cable is wound on the second winch; a storage turntable which can be driven to rotate by an electric motor is arranged beside the second winch, and a connecting hook plate is arranged on the storage turntable; a rotatable second rubber roller is arranged between the second winch and the first winch; an anti-falling net is also arranged in the area surrounded by the two soft steel arm ballast tanks and the cross braces.
The support structure comprises: the sleeve is sleeved on the cross brace, and a supporting steel structure is welded on the sleeve; the transverse support is connected with two first limit baffles with an included angle of 90 degrees, and the sleeve is connected with a second limit baffle located between the two first limit baffles.
The top of the supporting steel structure is provided with a horizontal rod, and a first rubber roller is sleeved on the horizontal rod.
The support steel structure is connected with an eye plate, and the first cable is connected with the eye plate.
One of the first limit baffles is positioned in the plane where the two soft steel arm ballast tanks are positioned; the other first limit baffle is perpendicular to the plane and is positioned above the plane.
The second squeegee is provided in plurality.
Compared with the prior art, the invention has the advantages that the invention allows the jumper hose, the cable and the like to be placed in the mooring system for storage after being detached, so that the offshore floating device can take off the ship at the moment when the jumper hose, the cable and the like are separated from the offshore floating device, and the efficiency is much higher than that of the prior art in which the jumper hose, the cable and the like are required to be pulled to the offshore floating device for storage.
