Hydrodynamics

Technical Bulletin 2015

Summary

Marine and offshore structures are subjected throughout their operational lifetime to the constant action of water, waves, current and wind. So that hydrodynamic simulation is essential in evaluating both the overall dynamic behaviour and the structural loading and responses of ships and offshore structures.

Although that significant progress has been done over the years, some challenges remains as the accuracy requirement steps-up. The following papers are the visible iceberg tip of the BV marine & offshore research. Some of them are long term research (Rankine/Kelvin hybrid method) to prepare the future, while some others bring immediate improvements to rules and tools used by the industry (dynamic positioning, reliable estimation of short term maximum, gangway motion in multi-body analysis or better Morison loads in sea-keeping analysis).
