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.

The article deals with the problem of ship’s ocean route programming. For masters during planning the ocean most convenient route lots of factors are very important such as among others: current, forecast weather, criteria and restriction, speed and fuel characteristic of ships on waves and wind and so on. These elements when are properly identify and adopted allow the master for making an effective ship’s course and speed decision. The aim of research is to show how the SPOS system is treated during the ocean’s ship route. 39 captains of PŻM ships during the year of 2014 answered on 9 questions of questionnaire which were concerned the degree of utilization of SPOS (Ship Performance Optimization System) during the operation of their ships. All the masters confirmed that they use of SPOS system as a browser weather, while only 25.6% of masters confirmed that they also use the SPOS system as a tool in planning the route. They also repeatedly pointed out, however, that SPOS has some of limitations such as not limited information about ice cover or tropical cyclones, etc. In conclusion, it can be assess that the SPOS system is satisfactorily used on ships as a browser forecast, but does not work well in planning the trip by navigators.
