Ship route programming in restricted and coastal areas in tropical cyclone regions

The article describes various methods used for tropical cyclone avoidance maneuvers during navigation in restricted and coastal waters. The avoidance maneuvers were carried out with the use of the following methods: the ORS (Onboard Routing System) systems, Bon Voyage 7.0 and SPOS 7.0, the 1-2-3 rule recommended by the US national weather administration NOAA (National Oceanic and Atmospheric Administration), the graphic-manual anti-collision plot, as well as the assistance and recommendations of the shore based AWT (Applied Weather Technologies) Centre. The weather and operational data that were used were from the actual voyage of the 9000TEU container ship POSTPANAMX, from Yantian (China) to Vancouver (Canada), which took place in August 2015. During this voyage the ship encountered the tropical cyclone SOUDELOR.
