Summary

 
Object and purpose of research.The purpose of this work is to analyze application specifics of numerical simulation in design of marine structures, as well as to demonstrate key points in reliability of simulation results.
Subject matter and methodsThe examples discussed in this paper are based on CFD methods. Viscous flow parameters are obtained through unsteady Reynolds equations closed by turbulence model and solved by the finite volume method.
Main results.KSRC activities in introduction of numerical simulation technologies to design of marine structures have shown that these technologies are quite helpful in solving current challenges in design and upgrade of high-tech assets, being successful rivals of physical modeling and sometimes the only way to solve the problem. However, as demonstrated by case studies discussed in this paper, numerical simulation of physical processes and phenomena must be addressed as thoroughly and thoughtfully as physical modeling, to avoid making errors and facing their outcomes in design solutions.
Conclusion.State-of-the-art computers and numerical simulation technologies can reduce the scope of physical experiments and if these are absolutely necessary, considerably supplement them. Today, transition to digital production technologies is a global trend, so these technologies must be taken into account in development plans and concepts of shipbuilding enterprises.
