In a majority of ports, a ship’s speed is limited for reasons of navigational safety. At the same time, captains and port pilots choose the speed of the ship, but it cannot be higher than the speed allowed in the port. Therefore, the speed of the ship also depends on the experience of the masters and harbor pilots and the sailing conditions in specific situations. Choosing the optimal speed of the ship in the port, considering the hydrodynamic effect of shallow water and the controllability of the ship, can help reduce fuel consumption and ship emissions, which is important for the development of a sustainable port. In all cases, the safety of the shipping is the highest priority. The main objectives of this article are determining the optimal speed of ships in ports with low clearance under a ship’s hull, ensuring navigational safety, reducing fuel consumption and emissions, and creating a sustainable port. This article presents the methodology for calculating the optimal ship speed as the minimum controllable speed, fuel consumption and emission reduction, as well as its implications for sustainable and green maritime transport and port development. The methodology presented has been tested on real ships and using a calibrated simulator, navigating through port channels and port water’s restricted conditions.

“…To support quantitative safe ship operation guidelines, ship trajectory data based on AIS information may be applied [50]. These data may be used to improve the reliability of ships' position information, especially in ports and other safety-critical areas [51]. The application of land-borne laser rangefinder measurements for navigation safety assessment was proposed [52].…”

Navigational channels and approaches to ports may have bends that constitute the specific sailing conditions for ships. A vessel’s entrance into a bend and its safe passing depends on the ship’s position accuracy, turn angle, and internal and external forces influencing the ships, as well as the captain’s or pilot’s experience. In order to assure a ship’s safe navigation under specific conditions, the possibility to measure individual ship movement parameters with the use of special sensors is needed to accurately calculate the ship’s trajectory considering the specific dimensions of ships. Moreover, hydro-meteorological and hydrological limitations for ships with different parameters and maneuverability should be evaluated in advance. The article aims to develop the methodology for calculating ships’ route trajectory in channel bends and approaches to ports under special navigational conditions. The mathematical model that may be used to calculate wind velocity limitations and distance crossed by a ship during maneuvers, depending on the ship’s maneuverability, hydro-metrological, and hydrological conditions, was elaborated. The methodology was verified by the example of a few ships entering specific channel bends. Wind velocity limitations depending on wind direction for the SUEZMAX tanker and other selected types of ships during crossing navigational channel bend near Klaipeda port were calculated. The presented theoretical basis may be used by ships’ captains and pilots who plan and perform operations of vessels’ crossing the approaches to ports and navigational channel bends, as well as by navigational channels designers who plan the channel’s parameters in difficult geographical and navigational conditions. Its application may influence the safety increase of maritime transport in limited or specific areas.

“…Generalized ship maneuvering models based on the real-time modelling of ships navigating in ports are accessed and presented in [10,11,20,[33][34][35][36][37][38][39]. Two models of the prediction of ships' trajectories have been developed and considered the probability of ships leaving the channel or encountering navigational obstacles [20]: (1) an Auto Regressive and Moving Average eXogenous (ARMAX) model is adopted to identify the ship steering dynamic system; (2) the stochastic sequences of the inputs for the first model used are generated using a semi-Markov model.…”

Port tugs bring large vessels into the port and take them out of the port, assist them during mooring and unmooring, move vessels from one mooring to another, tilt vessels, tow port barges, transshipment mechanisms, dredgers and other floating objects. Calculation and evaluation methods of the optimal request for tugs bollard pull port operations, are very important in order to guarantee the navigational safety of the port and ships during the main ship operations in the port. The most dangerous situations are situations of sudden failure of the power plant when maneuvering a vessel in the confined waters of ports, when tugboats become the only means of control that can prevent an accident. This is observed when the vessel moves in an area with hazardous sections of the waterway, calls into and out of the port, as well as when performing mooring operations. Line and / or port pilots, as well as tugs for escorting, escorting or when performing mooring operations of the vessel, are additionally involved in the process of navigating the vessel. In foreign ports, there are also very tense conditions in command management due to language barriers and the need for synergistic interaction of individual independent ship crews without prior preparation for a responsible mission. In this paper done a focus to improve tug possibilities and decrease navigational risks in port areas by method of balance handling forces. Such decrease in risks at ports is important issue to overcome, since the correct and proper usage of port tugs could highly improve the situation there. Keywords: tugs, emergency situation, port maneuvering, energy balance of the control force.
