“…Moreover, the vast majority of authors are experienced seafarers who reflect in their work personal experience in managing ships in extreme conditions. Thus, in the work of authors [17] the evaluation and construction of structural modular mathematical model to forecast ship's maneuverability is performed. It was also performed for modeling real-time maneuvering depending on the influence of natural factors, among which one of the main is the wind.…”

Simulation modeling is one of the most commonly used methods of studying the functioning of complex systems to assess possible risks. The use of simulation methods allows us not only to conduct a detailed analysis of the situation, but also to assess the probability of avoiding or appearance of a threat. The ship's crew must be staffed by qualified seafarers who have received a favorable decision from the management of crewing companies. Such commissions assess the applicant's competence at the international level, as he must work on ships of the world fleet. Therefore, among the tasks facing higher maritime education, one of the main is the formation of key competencies, the degree of formation of which is assessed at the international level. Over the last 5-6 years, Kherson State Maritime Academy has radically changed the training programs for maritime professionals, implementing a competencybased approach to training. The program of "Information Technologies" course, which is studied by 1st-year cadets, contains "Information Technologies in Navigation" module, which examines the algorithms and methods of solving professionally-oriented problems. The specificity of such tasks involves the use of simulation methods, algorithmization, the ability to use modern computer programs. This content of the course contributes to improving the quality of training of future ship navigators, and implementing the focus of this course on their professional activities. In other words, we begin to form both subject and universal professionally-oriented competencies. This article proposes methodological techniques for the formation of subject professionally oriented competencies of future ship navigators. These techniques are shown on the example of solving an applied problem using an information-modeling approach to the analysis and risk assessment of a ship operating in conditions of changing or unpredictable external influences. These influences are one of the factors that can lead to emergencies.

A ship’s body plan is a vital data resource of ship hydrodynamics analysis, especially for time-domain simulations. Motivated by 3D printing technology, a novel dense body plan generation method is developed in this study. The slicing algorithm is adopted to generate dense 2D body plans from ship stereolithographic models. The dense body plan can be produced automatically under arbitrary rotational angles and slices. Moreover, a section redistribution algorithm is integrated to eliminate the non-uniform distribution features in sliced data inherited from the stereolithographic models. The benchmark ship models are selected to validate the accuracy of the method. The hull volumes of three ship models are calculated based on the produced data. The calculated results show satisfactory agreement with the published values. Furthermore, the estimation formulas of wetted surface area (WSA) are reviewed and utilized for validation. The calculated WSAs by slice integration turn out to be adaptive and accurate. The time costs of different slices are provided to illustrate the computational efficiency. A ship hydrodynamic coefficients database is constructed based on a 2D strip method and the produced data. The proposed method aims to improve the generation process of the body plan, which could meet the accuracy requirements of the strip method. As a result, hydrodynamic coefficients utilized in time-domain simulations could be obtained smoothly from the database.

“…A high simulation fidelity usually involves very many convoluting concepts, and is data-intensive and computationally demanding. For example, it performs the mapping from the frequency spectrum of the observed stochastic ocean wave data, to the nonlinear dynamical response of the marine vehicle in time domain while simultaneously, taking into account of the hydrodynamic reactions, onboard payload, and sailing conditions [78][79][80][81][82][83][84][85]. As a result, it requires a very powerful software tool.…”
