INFLUENCE OF MAIN TRENDS IN CRUISE AND FERRY TRANSPORTATION ON THE INFRASTRUCTURE OF SEA PASSENGER PORTS AND TERMINALS

The article considers decision-making options for modernizing the infrastructure of sea passenger ports, depending on the influence of the external environment. Particular attention is paid to the current trend to increase the size of cruise and ferry ships. The considered problematic is actual for all large and specialized sea passenger ports. The authors prove the relevance by citing sample works from 2013, which offer options to justify such decisions. The article provides current statistics on passenger turnover from 2011 to 2022, providing a detailed analysis of work intensities. The authors consider in detail the port of Dubrovnik and the Passenger Port of St. Petersburg "Sea Facade". Revealing the problem, the authors consider the model of interaction "city-sea passenger port" by G. Norcliffe, and give a separate stage in the development. For the solution of the set problem the authors give target function, allocate basic criteria and give results of modeling intensities of cruise and ferry lines work in the port. Authors substantiate necessity of choice of some optimum quantity of ship calls, thus they allocate necessity of entering parameters describing sizes of cruise vessels, or entering separate condition of allocation of specialized berths for big liners both in the model of target function, and in the simulation model. The given conditions should be included in the digital simulation model and will allow increasing the accuracy of decisions on modernization of berths of the sea passenger port.
