Resistance and Propulsion Tests

Today resistance and propulsion tests performed in certified model basins are a fundamental prerequisite for the necessary EEDI certification of each newly built ship. HSVA’s large scale facilities, the 300 m towing tank is an approved site and recognised by all leading classification societies providing EEDI certification services.

As fuel oil prices and legislative pressure due to climate change are forcing ship owners and operators to put energy efficiency at the top of the agenda for the operation of their existing fleet and when planning newbuildings, towing tank tests play an important role to prove the effect of all optimisations. HSVA has published a number of articles in their NewsWave magazine which present the results of recent developments in this field:
