The Importance of CATZOC in Passage Planning and Prioritization of Strategies for Safe Navigation

Abstract

Maritime transport has a significant share in world trade. The unsafe operation of ships causes loss of life, loss of cargo, and marine environmental pollution. Commercial ships are equipped with advanced types of equipment. The nautical charts as aids to navigation are used on commercial ships to navigate safely between ports. The officer of the watch can see the risks in the navigation area by checking these charts. The risks indicated on the chart should be taken into account during the navigation of ships, and if the correct calculations are not made, serious accidents may occur. These calculations are based on both sufficient maritime experience and knowledge. This research studied the category zone of confidence (CATZOC) areas in ECDIS on ships, the limitations of the system, and their solutions. Recommendations received from experts for the solutions to the identified problems were determined and explained according to the priorities with the Fuzzy Analytical Hierarchy Process (FAHP) method.
