Abstract
Object and purpose of research. The study deals with the problem of defining the integral external loads on the ship hull by various methods with subsequent comparison of system responses. Materials and methods. For determination of external forces in regular waves the strip method and panel method are used based on the boundary element technique. Main results. Response amplitude operators (RAO) of bending moments and shearing forces for different wave headings obtained by various methods are compared. Calculation procedures are analyzed. Conclusion. The problem of defining the external forces on the ship hull was solved and numerical hydrodynamic procedures were analyzed in the work. Results show that both methods are practical, while the panel method provides a wider range of possibilities to input and include non-linear parameters.
