ABSTRACT
The paper presents a framework of a planned ship collision alert system. The envisaged system is compliant with IMO Resolution MSC.252 (83) “Adoption of the revised performance standards for Integrated Navigation Systems (INS)”. It is based on a ship domain-oriented approach to collision risk and introduces a policy of alerts on dangerous situations. The alerts will include cautions, warnings and alarms, which will be triggered by predicted violation of a ship domain or predicted passage in the domain’s proximity. The paper includes a description of the policy of alerts and examples of generating them for potentially threatening situations.
