Opis:
Technological innovations gives the opportunity to create so-called Smart Ports. However, determining which technologies to choose, how to implement them remains a challenge. The research problem presented in the article is: Is the constant introduction and implementation of the concept of intelligent ports an irreversible trend determining the direction of development of modern seaports? The aim of the article is also to analyze projects introduced in the ports of the North Sea and Baltic Sea which are successively implementing the concept of a Smart Port. The article uses the method of analysis - mainly current analysis and prospective analysis.

Opis:
The paper addresses the sensitivity of a novel method for quantifying the environmental risks associated with the current-driven transport of adverse impacts released from offshore sources (e.g. ship traffic) with respect to the spatial resolution of the underlying hydrodynamic model. The risk is evaluated as the probability of particles released in different sea areas hitting the coast and in terms of the time after which the hit occurs (particle age) on the basis of a statistical analysis of large sets of 10-day long Lagrangian trajectories calculated for 1987–1991 for the Gulf of Finland, the Baltic Sea. The relevant 2D maps are calculated using the OAAS model with spatial resolutions of 2, 1 and 0.5 nautical miles (nm) and with identical initial, boundary and forcing conditions from the Rossby Centre 3D hydrodynamic model (RCO, Swedish Meteorological and Hydrological Institute). The spatially averaged values of the probability and particle age display hardly any dependence on the resolution. They both reach almost identical stationary levels (0.67–0.69 and ca 5.3 days respectively) after a few years of simulations. Also, the spatial distributions of the relevant fields are qualitatively similar for all resolutions. In contrast, the optimum locations for fairways depend substantially on the resolution, whereas the results for the 2 nm model differ considerably from those obtained using finer-resolutionmodels. It is concluded that eddy-permitting models with a grid step exceeding half the local baroclinic Rossby radius are suitable for a quick check of whether or not any potential gain from this method is feasible, whereas higher-resolution simulations with eddy-resolving models are necessary for detailed planning. The asymptotic values of the average probability and particle age are suggested as an indicator of the potential gain from the method in question and also as a new measure of the vulnerability of the nearshore of water bodies to offshore traffic accidents.

Opis:
Marine passenger ports are integrated into the transport systems of cities and regions today. If there are sufficient developed mathematical forecasting models in the class of polynomial models, probability series, and a number of others, then the models describing the influence of the external environment on ferry market are not sufficient. The developed scheme of interaction between the participants of the cruise market and the mathematical model of the port as a technical system is presented in this research. The article substantiates new purposes to use the logistic function to assess the external environment. A mathematical model and the derivation of the new basic equation of the logistic function for ferry market are given. Analytical data were collected on the ports and terminals of the Adriatic Sea and the Baltic Sea, and data were selected of ship calls at the passenger port St. Petersburg “Marine Facade” (2019-2020). The article proposes the consideration of new various proportionality factors that will determine the demand for cruise transportation modeling in the short-term forecasting interval. A complete mathematical model is given taking into account the real schedule of the sea passenger port. The logistic function proposed in the article allows us to solve the forecasting problem in a new way in relation to the selection and evaluation of a cruise product. Moreover, it allows us to solve a group of economic problems related to promotion problem for particular cruise product on the market, allows us to evaluate the activity of passengers when they are choosing a cruise product, and allows us to make adjustments to the planned port working schedules and to make timely adjustments. The main advantage of the proposed model is an analytical assessment of the effect of the external environment, both on passenger ports and on ferry and cruise companies.
