The invention provides a monitoring and early warning method for coastal port ship operation conditions, which particularly comprises the following steps of: establishing a wind data database through historical data collection and field actual measurement data to obtain field monitored wind data and predicted wind data; establishing a wave data database to obtain field wave monitoring data, predicted sea wave data and predicted wave data at a berth; establishing a tidal current data database, firstly establishing a tidal current mathematical model of a port area, and providing tidal current prediction data of a dock berth; establishing a ship dynamic response data database, establishing a ship motion quantity response mathematical model aiming at a specific ship type in the port area, predicting the corresponding values of ship motion quantity, mooring force and fender impact force corresponding to the ship fender force based on the predicted by the wind wave conditions in the above steps; and according to the PIANC specifications and related standards, evaluating ship motion quantity, mooring force and fender impact force of a mooring ship and giving a corresponding early warning grade. -1/1 On-site monitoring -ofwinddata Wind data database o iddt Predicted wind data ---Oen sea wave data] prediction Monitoring and early Wave data database Berth wave data warning prediction method for coastal port On-site wave ship monitoring data operation conditions Tidal current data - - --- ___Fedbckmasurdreult predictionFeedbackmeasuredresults Tidal current data _ to predicted data, perform dantq ha -eself-learning and optimize On-site monitoring prediction algorithm d ata -.-.- ..- ..- . __On-site monitoring data Feed back measured results Ship dynamic to predicted data, perform response data Motion response self-learning and optimize database data prediction . . prediction algorithm Motion response data prediction Fig. 1
