Abstract
The article presents a comprehensive mathematical model for risk assessment in slow steaming conditions, integrating energy efficiency, greenhouse gas emissions and operating costs. Simulations for different types of ships in several speed scenarios were carried out, which allowed the determination of the relationship between fuel economy and the accumulation of relevant risks associated with the human factor, technical malfunctions and adverse weather conditions. An integral performance indicator that considers both environmental benefits and potential costs of eliminating the consequences of accidents is proposed. The simulation results have revealed the existence of an optimal speed range for each type of ship, at which the best compromise between energy and environmental efficiency and operational safety is achieved. Dynamic risk modeling has shown that long voyages without the adaptation of control and prevention systems lead to a rapid increase in the cost of eliminating the consequences. The results obtained are of practical value for shipping companies to develop adaptive strategies for managing the speed of vessels that combine environmental goals with ensuring the safety and financial sustainability of maritime transportation.
