The Online Hydroelasticity for Ship and Marine Training Course focuses on the study of hydro structure interactions in off-shore and naval applications. It covers the determination of operational profiles, deterministic hydro-structure interaction tools, and structural integrity criteria verification. The course is designed for engineers, scientists, MSc, PhD students, and personnel from ship management companies, oil companies, classification societies, and ship builders. It offers a balance of theory and practice, with lectures on environmental conditions, loads on bodies, seakeeping, structural response, use of CFD, and design methodologies. The course spans 3 days and is led by Šime Malenica, an expert in hydrodynamics.
