“…The hydrodynamic coefficients of an ROV (Remotely Operated Vehicle) were presented by Avila and Adamowski (2011), who showed that the influence of the amplitude of oscillation was higher than that of the period on the coefficients. A similar conclusion was obtained in the study by Mentzoni et al (2018), where simplified subsea structures were experimentally tested, and by Du et al (2020), analysing the hydrodynamic coefficients of a subsea manifold. Further, Solaas and Sandvik (2017) presented a series of results for the hydrodynamic coefficients of suction anchors; and Computational Fluid Dynamics (CFD) was used by Holmes et al (2016) to evaluate the hydrodynamics of Blow-Out Preventers (BOP) as a function of KC.…”

“…Computational fluid dynamic calculations are also used to predict ship manoeuvring time by Liu et al (2018). This methodology is also applied to scrutinize hydrodynamic effects and analyze responses (Du et al 2021). One of the most popular machine learning methodologies, support vector machine is used to diagnose parameters in ship manoeuvring by Wang et al (2021).…”

Currently, in practice, ship captains are responsible for decision-making during the manoeuvring process. However, this could be improved upon by the assistance of a decision support system. Any cost reductive initiative is significant to contribute to the overall viability and economic sustainability of the industry. Therefore, it is worthy to study time and cost efficiency of ship manoeuvring when approaching the port. This study develops a decision support system model by utilizing a goal programming integrated ship manoeuvring methodology, which examines ship and environmental variables concerning manoeuvring. The methodology enables positive resultant force of the ship and tugboat against negative external parameters with minimum effort and time. A case study was then carried out using 2 different container ships approaching Gemport berths in Turkey, to show the practical applicability of the methodology. The results of the case study showed that it would be possible to reduce manoeuvring time in approaching the port from 31.6 minutes to 27.36 minutes in ship I and from 59 minutes to 48.05 minutes in ship II. These results are significant as they can provide cost efficiency for ship owners and port authorities, especially when we consider its applicability for the entire world merchant marine fleet.
