ABSTRACT: The introduction of Maritime Autonomous Surface Ships (MASS) in maritime transport creates new challenges that did not previously exist in the case of manned ships, and changes the approach to voyage planning, implementation and monitoring. MASS is not only supposed to be more economical, but also contributes to transport safety and environmental protection, while limiting the impact of the human factor. Taking into account the assumptions of the International Maritime Organization, the implementation of a MASS voyage, supervised by the operator of the Remote Operations Centre (ROC) will require a high level of situational awareness. The paper discusses the determination of the MASS safe navigation domain by ROC operator making decisions under risk conditions. It is expected, that according to Kahneman and Tversky's prospect theory, the enlargement of MASS domains may result in an increase in human-induced navigation hazards, especially in restricted areas.
