Monitoring and early warning methods for ship operating conditions in coastal ports

Abstract

The invention provides a monitoring and early warning method for ship operating conditions in coastal ports, which specifically includes the following steps: establishing a wind data database through historical data collection and on-site measured data to obtain on-site monitored wind data and forecast wind data; establishing a wave data database to obtain On-site wave monitoring data, predicted open sea wave data, and predicted wave data at berths; establish a tidal current data database, first establish a mathematical model of tidal current in the port area, and give tidal current prediction data for berths; establish a ship dynamic response data database, Establish a ship motion response mathematical model for a specific ship type in the port area, and predict the corresponding ship motion, mooring force and fender impact force values ​​based on the wind, wave and current conditions predicted in the above steps; evaluate the mooring according to PIANC regulations and related standards The amount of movement of the ship, the mooring force and the fender impact force give the corresponding warning level.

Description

technical field [0001] In the field of port channel and offshore engineering technology, especially the comprehensive condition forecast and early warning technology for ship operations in coastal ports. Background technique [0002] As an important reference factor in the operation of seaport terminals, ship operating conditions will affect ship berthing operations, terminal loading and unloading scheduling, etc., and then affect the economic benefits of terminal operations. Wharf mooring safety, reasonable production scheduling, etc. have very important economic benefits and safety significance. [0003] According to research, the annual throughput of my country's coastal ports has exceeded 12 billion tons, and the crude oil throughput has reached 420 million tons. The investment in coastal port construction has been maintained at more than 85 billion yuan for many years, and the status of a port power is prominent. The survey found that due to the limitation of construct...

AI Technical Summary

Problems solved by technology

The survey found that due to the limitation of construction conditions, during the operation of the port, the operating conditions of berths at different locations are quite different, the production efficiency is different, and there are still great hidden dangers in certain berths.

For example, the offshore berths of some small and medium-sized ports and the large berths near the entrance are relatively poorly protected and are greatly affected by open sea swells.

[0004] At present, the wave forecast of the marine system is mainly aimed at a certain sea area, and has not directly served specific ports and terminals, and the wave forecast only has wave height, no wave period, and lacks pertinence and effectiveness for port production operations
