Embodiment approach
[0046] As a specific implementation of the offshore crude oil transfer method provided by the present invention, the oil receiving process of the second-pass ship adopts single-side unloading, and the VLCC second-pass ship used for loading and unloading crude oil is towed by a full-turn wheel with a fire-fighting function Securely berth on one side of the ULCC. After all the mooring strong cables are fastened to the second-leg ship, first connect the electrostatic cables between the two, and then use a crane to connect the oil pipeline to the second-leg ship that unloads the VLCC. For the air return pipe between the two ships, after confirming the tightness and all safety items of the ULCC and VLCC two pipes and checking each other, the captain of the ULCC will issue an order to open the pump to carry out the oil receiving operation after the countersignature of both parties is correct.
[0047] Double-side oil unloading can also be used for the oil receiving process of the two...

The invention provides an offshore crude oil lightering platform, and belongs to the technical field of offshore crude oil lightering. The offshore crude oil lightering platform includes a ULCC, wherein a hull of the ULCC is internally provided with a plurality of clean ballast tanks; and an anchoring structure for fixing reinforced anchor chains is arranged on a bow deck of the ULCC, and a reinforced structure for supporting the anchoring structure is arranged under the bow deck.The invention further provides an offshore crude oil lightering method which includes the following steps that A, ballast water is injected into the clean ballast tanks; B, a first carrier berths and receives oil while the clean ballast tanks drain outwards; and C, a second carrier berths and receives oil. The offshore crude oil lightering platform and the offshore crude oil lightering method utilize the ULCC as the lightering transfer of offshore crude oil, the problem of serious port congestion of VLCC is solved, and the stability of the lightering platform can be maintained.
Description
technical field [0001] The invention belongs to the technical field of offshore crude oil transfer, and more specifically relates to a method for offshore crude oil transfer. Background technique [0002] With the continuous economic development and the improvement of people's living standards, my country's crude oil imports have risen rapidly. However, due to the limitation of the number and unloading capacity of VLCC (Very Large Crude Carrier) terminals, the number of unloaded VLCCs in the country's deep-water crude oil ports is seriously under pressure. The way to solve the problem of VLCC port pressure in the prior art is to implement offshore crude oil transfer, dock the VLCC in the deep water area, use multiple second-pass ships to unload the crude oil in the VLCC, and transport it to various crude oil storage depots. Although the barge method solves the problem of VLCC pressing the port, it will waste a lot of time for the VLCC to berth and wait for the second-leg shi...
