%X The paper presents the readiness/safety model for the sea voyage of Maritime Autonomous Surface Ship (MASS), based on Semi-Markov process. The states of MASS during the voyage were defined as triplets of intentional type of MASS operations, reliability state and safety state, dependent on weather conditions. The determined states were aggregated, and the disjoint subsets were used to build a macro-model of MASS voyage process. An example of changes of MASS states during the sea voyage, for Gdynia - Port Everglades connection, is presented and discussed in the paper. The Semi-Markov process was used for the analysis of MASS reliability and safety during the sea voyage. The obtained matrix of transition probabilities between the states of MASS during the voyage can be used by MASS operator in Remote Operations Centre to make decisions related to voyage planning. The proposed model can constitute the basis of a computer program supporting the decision-making process of the operator.
