In this article, models of preventive and timely effective operations of the ship against possible pirate attacks have been systematically analyzed, as well as the actions of the defence ship against pirate attacks during the sailing in piracy areas and beyond. Based on the results, after carrying out the research, the model of prevention of possible pirate attacks against the ship was made, with developed Risk Assessment model, Game Theory model, and proposed improvements to protect the ship against pirate attacks by means of simulations of different attacks scenarios made by the use of Petri nets
