Description

Technical Field

[0001] The invention belongs to the technical field of ships, and in particular relates to a sea patching pipe deflection buoyancy device and a use method thereof. Background Art

[0002] During the ship operation phase, it is necessary to carry out longitudinal oil and water supply and reception. The supply ship and the receiving ship are basically in the same straight line. The front ship places the pipeline, and the rear ship salvages, docks, and receives. After receiving, the ship puts the pipeline back and turns to leave. In this process, the front and rear ships are basically in the same straight line, and there is a certain risk of collision.

[0003] The marine environment is complex and changeable. Under the influence of changes in environmental factors such as waves, currents, surges and wind, ships are at risk of stalling or accelerating. When carrying out longitudinal oil and water supply and reception, the front and rear distances of the two ships need to be strictly controlled. Relevant meetings are usually required to clarify mechanisms such as cutting the cable and turning separately in case of emergency.

[0004] The invention patent with the publication number CN107571973A discloses "an external transmission pipeline system for deep-sea supply ships", including a delivery hose, a delivery outer protective pipe, a delivery inner protective pipe, a hydraulic support outer pipe, a hydraulic support rod and a hose end member; wherein the delivery inner protective pipe is slidably connected to the inside of the delivery outer protective pipe to form a telescopic pipe structure; one end of the delivery outer protective pipe is connected to the side of the deep-sea supply ship through two rotating bolts; one end of the delivery hose is connected to the deep-sea supply ship, and the other end passes through the telescopic pipe structure and a hose end member is arranged at the end; the telescopic length of the hydraulic support rod is controllably arranged at one end of the hydraulic support outer pipe, and the other end of the hydraulic support outer pipe is connected to the side of the deep-sea supply ship through a rotating bolt, and the other end of the hydraulic support rod is hinged to the lower side of the delivery outer protective pipe. The technical solution sets the delivery outer protective pipe and the delivery inner protective pipe in the form of a telescopic pipe, and sets a steel ball and a limit structure between the two, so that the two can slide smoothly, and at the same time, releases the freedom of distance change between the deep-sea supply ship and the deep-sea operation ship.

[0005] The above technical solution can flexibly adjust the longitudinal distance between the supply ship and the operating ship, but when dealing with emergencies or bad weather, there is still a certain risk that the supply ship and the operating ship are in the same straight line.
