“…In particular, stability issues of vessels with a small engine are frequently reported, and the Marine Environment Protection Committee (MEPC) of the IMO has proposed a guideline for minimum propulsion power to maintain the maneuverability of ships under adverse conditions [2]. In this regard, various studies on the performance of ships in waves have been actively conducted, mainly by JASNAOE (the Japan Society of Naval Architects and Ocean Engineers) in Japan, SHOPERA (Energy Efficient Safe Ship Operation) in the EU, and an R&D project of KRISO (Korea Research Institute of Ships and Ocean Engineering) in Korea [3][4][5][6][7][8]. It is essential to evaluate the ship performance in waves, and the accurate estimation of the wave drift force on the advancing ship is considered increasingly important.…”

In this study, experimental and numerical methods were applied to estimate surge and sway wave drift forces and yaw drift moment acting on KVLCC2, advancing in oblique wave. An experiment was carried out in the ocean engineering basin of the Korea Research Institute of Ships and Ocean Engineering (KRISO). A series of regular wave tests under various heading conditions were conducted to investigate ship motion responses and wave drift forces. A Rankine panel method based on potential flow was adopted in the numerical analysis, and the direct pressure integration method that integrates second-order pressure on the hull surface was applied to compute wave drift force. Through this study, validation data of wave drift force acting on KVLCC2 was established, and the computation capability of the potential-based numerical method was systematically analyzed.

“…The analysis of the kinematics of the turning characteristics of the ship in regular waves the trajectory distortion presented by the drifting distance and by angle of the path evolvement originally was proposed by some Japanese authors like Ueno (2003). The results from the application of this approach were reported by Lee et al (2009), Milanov et al (2014), Sprenger et al (2017), Kim et al (2019aKim et al ( , 2009b. Manoeuvring behaviour of the vessels in irregular waves experimentally has been studied by Kim et al (2019c).…”

“…Consequently, the problem arises with the formulation of criteria for vessel manoeuvrability in real sea conditions. Following the gradual introduction of the EEDI requirements in recent years, several authors are applying similar or modified rationing methods for assessment of ship manoeuvrability in waves - Lee et al (2009c), Milanov et al (2014), Shigunov and Papanikolaou (2014), Shigunov (2018), Kim et al (2019a).…”

Since the Energy Efficiency Design Index EEDI was introduced by International Maritime Organization IMO, an increasing attention to the ship's controllability in waves, in particular at low speed is observed. One of the main reasons for this is the fact that, in order to satisfy the EEDI requirements, there is a tendency to reduce the power consumption and the propellers RPM reduction while maintaining existing control means, which results in reduced ship steerability mainly at low speed. This study considers the effect of regular sea waves on ship’s initial turning parameters at the set of service conditions. By means of free running model tests the influence of low advance speed on course and maneuvering trajectory changes in transient turning motion were investigated. The effects of the wave encounter angle variations were examined during the tests, including application of different wave lengths. Using the experimental results, an attempt was made to normalize the ship's handling in adverse sea conditions by applying a simple criterion based on the initial time to reach a given course. The results of the present study can be used for benchmarking of numerical simulations of low speed maneuvers in regular waves.

“…To analyze the turning trajectories in irregular wave and wind conditions, we applied the drifting distance and the drifting angle suggested by Kim et al (2019). The drifting distance  is the distance between lines that are perpendicular to the tangent to the turning trajectory, as shown in Fig.…”

The maneuvering performance of a ship on the actual sea is very different from that in calm water due to wave-induced motion. It is crucial to account for the ship's maneuverability in waves at the design stage. Numerous prior studies have investigated the maneuverability of ships in waves. According to the International Towing Tank Conference (ITTC) (ITTC, 2011), there are four methods of predicting the movements of a ship maneuvering in waves: experiments, two-time scale, unified theory, and contract for difference (CFD) methods.Yasukawa ( 2006) proposed a method of estimating the hydrodynamic force components, including added mass, wave damping, and wave excitation forces. In his study, the basic motion equations were divided into two groups, high-frequency induced motion problems, and low-frequency maneuvering problems.Yasukawa (2006, 2008) performed a free-running model test in regular waves using the SR108 container ship. The experiment was conducted with various wavelengths in head sea and beam sea conditions. Skejic and Faltinsen (2007, 2008) presented a seakeeping and maneuvering analysis of two ships. They focused on overtaking and replenishment maneuvers between two ships. Seo et al. (2011) applied linear and nonlinear ship motion analysis toanalyze ship-maneuvering performance in high-amplitude waves. The maneuvering performance of the S-175 container ship was discussed with regard to wave slope. Also, the wave drift force was calculated using the direct pressure integration method. Skejic (2013) presented a maneuvering simulation of ships in a seaway and discussed the significant role of unified maneuvering and seakeeping. Zhang et al.
