PETRI NET MODEL OF AHTS/PSV SUPPLY VESSEL AND CREW BOAT USABILITY IN NORTH ADRIATIC ON GAS FIELD IVAN

The demand for gas is increasing every day in all European countries. Therefore, the number of gas production platforms is also increasing. In Croatia, the most important gas field is 'Ivana', located in the northern Adriatic Sea. In this paper Petri nets and 'Yasper' tool are used to simulate the dynamic process of supply and operation of vessels. The simulation depends on the wind and wave conditions in the northern Adriatic Sea and the type of work performed by the supply vessel and crew boat in cooperation with the Ivana gas field. The input data are: Sea state and wind conditions in the northern Adriatic near the Istria peninsula, fuel consumption, type of vessel operation, distance between the port of Pula and the Ivana gas field, and the number of daily departures of vessels from the port. The report presents a model of discrete events in the process of supplying the Ivana gas field, leaving the Port of Pula until the completion of the works around the Ivana gas field and returning to the Port of Pula. The report can provide information about the usability of the vessels and the approximate costs of the supply vessels and crew boat on a voyage from the port of Pula to the Ivana gas field and back.
