Description

Technical Field

[0001] The invention relates to the technical field of crude oil transfer barges, and in particular to a crude oil transfer barge loading and unloading system based on pipeline transportation. Background Art

[0002] Traditional deep-sea crude oil transshipment usually adopts the combination of "FPSO (Floating Production Storage and Offloading Vessel) + Shuttle Tanker". Considering the complex sea conditions under the combined effects of wind, waves and currents near the FPSO operating area, shuttle tankers with good dynamic positioning performance can approach FPSO relatively well and complete the transfer of crude oil. However, the current international oil price continues to run at a low level, and the "FPSO + shuttle tanker" transshipment mode has a small amount of crude oil transported per time and a high transportation cost. Especially for long-distance transportation, this defect is particularly significant, which greatly compresses the profit margins of crude oil mining companies.

[0003] Compared with shuttle tankers, VLCC (very large crude carrier) has a larger single transport volume, which can greatly reduce the cost of offshore crude oil transshipment. However, the traditional VLCC ship type has poor dynamic positioning capability. If crude oil is transshipped close to FPSO, it needs to rely on complex multi-point mooring and the help of auxiliary ships to achieve a relatively stable state, and has relatively high requirements for the seabed conditions in the operating sea area. Therefore, in order to meet the above market demand and build a transshipment bridge between VLCC and FPSO, CTV (crude oil to barge) came into being; and the loading and unloading system is the key to CTV's core functions. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a crude oil transfer to barge loading and unloading system based on pipeline transportation, which can solve the problems of poor adaptability to the operating sea environment and high transfer cost of the traditional transfer mode using shuttle tankers in the deep-sea crude oil transfer process.

[0010] The crude oil input pipe lifting winch is arranged on the deck of the crude oil transfer barge on the same side of the input butt pipe on the loading station, and the output end of the crude oil input pipe is connected to the crude oil input pipe lifting winch, so as to provide traction for lifting the output end of the crude oil input pipe when the crude oil input pipe is connected to the input butt pipe.

[0011] Furthermore, the input docking pipe guide device includes a guide wheel, a hydraulic cylinder, a fixed shaft and a transmission arm; the fixed shaft is fixedly arranged on the outer plate of the side of the crude oil transfer barge, the transmission arm is connected to the fixed shaft through a slewing bearing so that the transmission arm can rotate around the fixed shaft, the output end of the hydraulic cylinder is connected to one end of the transmission arm, and the guide wheel is arranged at the other end of the transmission arm; the transmission arm is driven to rotate by the hydraulic cylinder to adjust the position of the guide wheel, thereby controlling the distance between the loading and unloading joint on the input docking pipe and the side of the crude oil transfer barge.

[0012] Furthermore, the loading and unloading joint is connected or disconnected by a connecting buckle, a sealing rubber ring is arranged in the loading and unloading joint, an emergency sealing valve is also arranged in the loading and unloading joint, and the emergency sealing valve is a solenoid valve with a spring structure.
