Summary

 
Object and purpose of research. The purpose of this work is to analyze applicability and reliability of calculation methods in ship hydrodynamics
Subject matter and methods.This analysis summarizes ITTC data and recommendations and KSRC experience of hydrodynamic calculations.
Main results. The paper compares maturity levels of various calculation methods applied to solve propulsion performance problems in the 1970s and in the 2010s, tackling various aspects of analytical approaches to such problems as ship resistance, wake surveys and propeller calculations.
Conclusion. The study identified the capabilities and optimal shares of today’s analytical and experimental methods used for propulsion performance tasks, as well as pointed out the limitations and requirements to calculation methods so as make them sufficiently accurate for practical tasks. Nevertheless, the study emphasizes that maneuvrability and seakeeping problems are still solved as per the mathematical models based on experimental coefficients, whereas solution of Reynolds equations for these tasks is currently at its primitive stage because it requires very performant computers.
