Description
Technical Field
The invention mainly relates to the technical field of offshore supply, in particular to an omnibearing floating fuel supply system and an operation method thereof.
Background
Bonded oil filling refers to the act of providing tax-free oil supply under customs supervision by the country for international navigation with the destination port being overseas and harbor in china, medium and foreign ships, according to the international common practice, and the act is regarded as export. The bonded oil enterprises can import fuel oil directly from the world, do not occupy the domestic fuel oil import quota, and are free from the tariff, consumption tax and value-added tax in the import link. The marine bonded fuel oil service is a necessary condition for enhancing the port service function and improving the port status. At present, China port logistics industry is rapidly developed, and the tax-protection fuel oil service for ships is increasingly urgent. According to the running state of the ship during the fuel supply operation, the fuel supply mode of the ship can be divided into aviation supply and anchoring supply. Among them, the supply of sailing is limited by conditions such as sea area environment, ship performance, special equipment, etc., and the pipeline connection and disconnection in the supply of sailing is complicated, resulting in too high operating cost, and is not suitable for the marine bonded fuel oil service. For mooring supply, the general mooring supply of ships can be divided into two forms of side-by-side export and series-by-side export. The side-by-side export is realized by berthing a supply ship on one side of a receiving ship in parallel and directly conveying an oil conveying pipe to the receiving ship through mechanical equipment to carry out fuel oil filling operation. The mode has the advantages that the needed oil conveying pipe is short, the fuel oil conveying control is rapid and convenient, the whole structure is simple, the operation cost is low, but the operation is difficult to carry out under high sea conditions, the mooring force is high, large relative heaving motion is easy to generate between a supply ship and a fuel-receiving ship, the adverse effects such as collision are easy to generate, and the safety is poor; the serial output is that the bow of the supply ship is connected to the stern of the oil receiving ship through a mooring cable, and the crude oil is conveyed to the oil receiving ship through a floating hose to carry out fuel oil filling operation. The mode can adapt to severe operation sea conditions, is suitable for ship mooring between different tonnages, effectively avoids collision between a supply ship and a ship receiving oil, has small mooring force, can realize quick release, but has the defects of longer floating hose, larger pipeline resistance, higher output pump power demand, and high requirement on the cost of the oil transportation ship because a special retraction device for the output hose is required to be additionally arranged.
