Technical Field

The embodiment of the invention relates to the technical field of ships, in particular to a ship parallel-leaning anti-collision device suitable for multiple sea conditions.

Background

When ships are supplied side by side, especially under the condition of extreme sea conditions, under the combined action of wind, waves and currents, because the gap 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.
