Calculation method of mooring ship load

Abstract

The invention relates to the technical field of mooring ships, in particular to a mooring ship load calculation method, which comprises the following steps of: calculating a wind load, a water flow load and a wave load suffered by a target ship at the previous moment according to a wind load calculation formula, a water flow load calculation formula and a wave load estimation formula; measuring the mooring force at the previous moment; according to the wind load, the water flow load, the wave load and the mooring force at the previous moment, the estimated stress of the ship at the previous moment is obtained; calculating the stress of the ship at the previous moment; judging whether the difference between the estimated ship stress at the previous moment and the ship stress at the previous moment is smaller than or equal to a preset error value; if not, the wave load estimation formula is corrected, and the wave load is estimated again; if yes, calculating the estimated stress of the ship at the current moment; the invention provides an accurate mooring ship load calculation method, which is favorable for establishing a safer and more effective ship mooring system and improving the safety and reliability of the whole operation.
