In this paper the hydrodynamic design procedure for Energy Saving Devices (ESDs) developed in the FP7 EU project GRIP is applied to full scale validation vessel – a newly built handymax Bulk carrier by Uljanik shipyard in Croatia. Three ESDs such as a Pre-Swirl Stator, a Pre Duct and a Rudder Bulb have been designed for this ship by three partner – HSVA, MARIN and VICUS respectively. From the three ESD designs that were submitted, the most promising alternative was selected via a thoroughly performed cross check by all participating partners. For the ESD selection, the hydrodynamic performance of the ESD is the most but not the only important factor; other aspects, such as cavitation risk, structural, manufacture and installation aspects have also been considered, but will not be covered in this paper. The finally selected ESD was HSVA’s Pre-Swirl Stator, which has been developed further and successfully tested during the trials of the full scale ship. In this paper only the conceptual design of PSS during the ESD hydrodynamic design phase and the results of the cross check which has been performed for the selection of ESDs will be presented.
