At present,the berth safety control of domestic liquid bulk cargo terminals still relies on manual experience,which is difficult to meet the requirements of full process,integration and unmanned,and there are many risks in ship berthing and unberthing operations.With the development of specialized and large-scale liquid terminals,safe operation control needs to take more effective measures on the new concept.Based on the refined prediction of waves,this paper proposes a set of intelligent safety management and control technology for liquid bulk cargo terminals to predict the ship motion,and avoids the risk actively.The paper puts forward the concept of ship operational readiness,assigns the index weight to the influencing factors of berthing operation,and builds its safety evaluation model to obtain the criterion of safety at berth.The results show that the application of this technology provides a powerful scientific basis for the decision-making of ship safety operation window period.
