The Study On Ocean Vessel's Optimum Route Designing Software System For Typhoon Evasion

Dozens of typhoons would happen every year all over the world. Due to the devastating winds, heavy rainfall, billow and storm tide, typhoon is a major threat to ocean ships. The improper measures to evade typhoon often cause damage to ships and cargo, and even sink ships and drown people. The present researches and applications on typhoon evasion are deficient in china. In order to meet shipping companies'requirements on typhoon evasion, this paper relies on the National Science & Technology Pillar Program "Ship and Cargo Online Monitoring System (SCOM)" to make researches on the Ocean Vessel's Optimum Route Designing Software System for Typhoon Evasion.On the basis of the present research status at home and abroad, this paper combines shipping companies'requirements with principles on typhoon evasion and uses track calculating method, target circle and radar plotting method. This paper researches on the necessity, the time and the measures to evade typhoon. In order to reduce the economic looses, the ship should return to the planned route or resume the planned speed at a proper time, so this paper studies on the route to return to the planed route or the time to resume the planed speed. When new typhoon information is obtained, the system should renew the route correspondingly. On the basis of global electronic chart, this paper programs and implements the Ocean Vessel's Optimum Route Designing Software System for Typhoon Evasion. By doing simulation experiments, this paper proves the correctness of the scheme and summarizes the sources of error.The system can reduce typhoons'impact on ships to some extent and ensure the economy and security of ships, so it meets the shipping companies'requirements on typhoon evasion.
