Hydrodynamic Optimisation and Model Testing Campaign for the prototype of a full electric fast catamaran successfully completed – the Stavanger Demonstrator

Under the EU H2020-funded TrAM project (2018-2022), a prototype of a fully electric passenger fast ferry has been developed. The Vessel undergoes detailed design and physical model testing, prior to its construction. The catamaran will start operation in Stavanger/Norway before the end of the TrAM project and be part of the city´s zero emissions urban transportation system.

HSVA is in charge of the hydrodynamic optimisation and model testing of the Stavanger prototype. In the frame of the initial design phase, a first hull form has been developed and tested in December 2019 in the large towing tank. Due to some changes in the battery arrangement, a modified hull form has been developed and tested at HSVA in May 2020. Compared to the hull form tested in December 2019, the new hull form showed improved hydrodynamic performance and reduced power requirement of over. 6% at the design speed of 23 knots, while savings are even higher than 10% at the speed range of 15-17 knots.
