“…However, it can be safer when a critical decision given by the onboard intelligent systems analyzing all changing parameters. On the other hand, these systems are important not only for safe navigation, but also for economic and sustainable operations (Akbar et al, 2021;Kurt & Aymelek, 2022;Kafalı & Aksu, 2022). Although it is thought that the transition to autonomous shipping is its infant age, there is an opportunity to operate ships under control with autonomous systems thanks to obtained positive outputs from sea trials.…”

A mathematical model is created to obtain safe navigation for ships in regular head waves in this study. To validate the suggested model, firstly, the added resistances are calculated for two different ships using empirical formulas in the mathematical model. Secondly, the turning test simulations are performed for calm water and in waves with various wave amplitudes. After these validation studies, the path following simulation of the ship to the target destinations is performed in both waves and calm water for the determined course. It is assumed that regular head waves affect the ship as an external disturbance. The wavelengths and wave amplitudes are changed systematically to understand their effect during the path following simulations. When the ratio of wavelength to ship length, λ/Lpp, is nearly 1.0, the path following simulation times increase. Moreover, when the value of wave amplitude increases, so does the simulation time.
