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 n

Abstract

The invention provides a method for monitoring and warning the work condition of ships in coastal port. The method including such steps as collecting historical data and on-the-spot measure data, establishing wind data database, obtaining on-the-spot monitored wind data and predicted wind data, setting up wind data database, collecting wind data and predicted wind data, setting up wind data database, collecting wind data and predicted wind data, setting up wind data database and predicted wind data; establishing a wave data database, getting wave monitoring data in situ, wave data of predictedopen sea, wave data of predicted berth. Firstly, the tidal current mathematical model of the port area is established and the tidal current forecasting data of the berth is given, a ship dynamic response data database is established, and a ship motion response mathematical model is established for a specific ship type in the harbor area, based on the wind, wave and current conditions predicted inthe above steps, the corresponding ship motion quantity, mooring force and fender impact force are predicted. According to the PIANC code and related standards, the amount of motion, mooring force and fender impact force of moored ships are evaluated, and the corresponding warning levels are given.

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...
