“…In the exploration of the entire ship's wind field, numerous scholars have adopted a Computational Fluid Dynamics (CFD) numerical analysis to delineate the inherent characteristics of the ship's wind fields. Several researchers have investigated the aerodynamic impact of wind field on whole ships, concentrating on factors such as the configuration of container ships [35], container simplification levels [36], assembly conditions under various wind speeds [37], and the effect of superstructure wind field [38,39]. Furthermore, several researchers [40,41] have examined the influence of the port's wind environment on entire vessels.…”

Due to the tall and large superstructures of cruise ships, the wind-induced vibration of frame structure on open decks cannot be neglected. This study investigated the wind-induced vibration of a typical frame structure on a cruise ship by using wind tunnel tests and numerical simulations. Wind tunnel tests were conducted to explore the simulation methods of the fluid–structure interaction (FSI). CFD simulations were performed to obtain the wind field data of the entire ship, which was utilized as an input for the open deck through the subdomain method. Subsequently, wind-induced vibration simulations of the guide rail frame structure on the open deck was carried out under various wind conditions. The results revealed that employing the turbulence model SST k-ω had a good agreement with the experimental data. The entire ship’s CFD results have a significant impact on the subdomain’s wind-induced vibration results. The vibration frequency of the guide rail frame structure was mainly concentrated between 0.8–10.1 Hz. The most unfavorable conditions appear at the wind attack angles of 0° and 120°. This study can provide some instructive insights for the prediction of wind-induced vibration and control of typical structures on the open decks of large cruise ships.

“…Janssen [15] presented RANS CFD simulations of wind loads on a container ship and validated with Andersen [14]. Seok and Park [16] also numerically studied the effect of the presence of the superstructure on the resistance, trim, and sinkage of an 8000 TEU-class container ship.…”

IMO presented the standard for ship’s manoeuvrability which every ship is recommended to satisfy. Although it specifies a full load and even keel condition as the condition at which the standard applies, practically, ships are operated under various loading conditions of cargo. From this viewpoint, the authors have conducted manoeuvring tests of a container ship under five loading conditions with different combinations of the draft and trim, and one of the authors established the manoeuvring mathematical model of the ship for each condition so far. This study focuses on the course-keeping performance of the same ship under these loading conditions under wind disturbance. It is the aim of this study to discuss both the influences of loading condition and wind condition simultaneously on the check helm and attitude of the ship while maintaining the target course. For this purpose, the arrangement of containers and their weight distribution were designed as exact as possible. For example, the ship with a trim by bow, which is commonly preferred for fuel efficiency, needs to have a larger check helm for course keeping, especially under the condition of wind disturbance diagonally from behind. This kind of knowledge would be useful for safe navigation.

“…However, the fulfilment of all the stability criteria does not guarantee the total safety of the ship. Therefore, it is important to avoid adverse weather conditions that may lead to, inter alia, shipping green water, shifting cargo or increased rolling [15,20].…”

As the maritime transport of containers continues to grow and container ships change in terms of design and construction, it is important to ensure the appropriate level of safety for this type of transport. Over the decades, the size and cargo capacity of container ships have been changing, and so have their manoeuvring restrictions and required stability criteria. It seems that changes in the regulations, technological development and increased stability requirements are not yielding satisfactory results – the causes of container ship accidents continue to show similar patterns. The present article refers to the problem of ensuring safety in sea container transport, with a particular focus on cargo processes. Its purpose is to determine cause-and-effect relations leading to the loss of containers at sea, and to develop a model of loading that could significantly raise the level of safety of container transport. The article provides a general description of threats to ships related to weather conditions, loading methods or stability limitations. A statistical analysis of the occurrence of damage and/or loss of cargo from container ships was carried out and the risk of cargo loss was assessed on the basis of data from 2015‒2019. A Pareto diagram was used for this purpose. The authors present the concept of the container ship loading model, which may contribute to increasing the safety of shipping in the future.
