Dynamic risk management method for service water domain in vessel traffic

Abstract

The invention discloses a dynamic risk management method for a service water domain in vessel traffic. The method is performed according to the following steps of (1), constructing an evaluation indexsystem; (2), establishing an evaluation word set; (3), determining an evaluation index weight; (4), establishing an evaluation model; (5), inputting data; (6), calculating a risk value by means of the evaluation model; and (7), according to an electronic sea chart system, respectively representing a high risk, a middle risk and a low risk by a red color, a yellow color and a green color, and performing relatively visual risk reminding, and supporting decision of an operator. The dynamic risk management method according to the invention focuses on analysis of a real-time traffic flow. The dataof real-time traffic flow come from harbor ship data of a VTS. Risk reminding is performed on on-duty personnel of the VTS in a relatively short time interval. High navigation safety of ships in theharbor is ensured.

Description

technical field [0001] The invention relates to the field of risk management, more specifically, it is a method that can automatically calculate the risk of the water area according to the real-time situation of the VTS water area, and can give decision support to the VTS personnel. Background technique [0002] The Tianjin port economy is developing day by day, the navigation environment of the port is becoming more and more complex, and the ships arriving at the port are showing a trend of diversification, large-scale and rapid development. These conditions pose new challenges to the ship traffic management of Tianjin Maritime Safety Administration. [0003] As the first artificially excavated two-way four-channel compound channel in China, the Tianjin Port compound channel will add a 10,000-ton navigation channel on both sides of the existing main channel after it is put into use, so as to realize the diversion of high-grade large ships and small ships. The formation of "...

AI Technical Summary

Problems solved by technology

[0004] The emergence of the double channel has effectively improved the efficiency of the channel and the two-way navigation capability, and solved the problem of small ships occupying channel resources. While bringing economic benefits, the risk of the port has increased and cannot be predicted manually.
