Description
Technical Field
The embodiment of the invention relates to the technical field of ships, in particular to a ship parallel-leaning anti-collision method suitable for multiple sea conditions.
Background
When ships are supplied in parallel, particularly under the condition of extreme sea conditions, under the combined action of wind, waves and currents, because the clearance between the two ships is narrow, hydrodynamic interference can be generated between the two ships. A number of observations indicate that hydrodynamic disturbances include not only first order forces, which cause the receiving vessel to generate a coupled kinematic disturbance response with the tender vessel; a second order steady offset force is also included that offsets the average position of the receiving vessel from the tender vessel. Due to hydrodynamic interaction, violent movement between the receiving ship and the supply ship is caused, so that offshore supply failure is caused, and more serious casualty accidents of people on the ship can be caused. Based on this, it is very important that ships lean on the anticollision device.
In the correlation technique, an inflatable rubber fender with a built-in safety valve is disclosed, and is used for isolating ships and ships, ships and docks.
However, the inflatable rubber fender with the built-in safety valve has the following defects: firstly, the flexible fender does not adapt to extreme sea conditions, secondly, the flexible fender is fixed in size and cannot control double ships to lean against the space, thirdly, the flexible fender is single in shape and cannot adapt to the linear outward floating of a ship body, fourthly, due to the airtightness of the fender and the parallel action of the double ships under the extrusion force, the pressure drop phenomenon of the fender can occur, and the bearing capacity is reduced.
