Video: TriCat HYSUWAC - Sea Trails, Hong Kong (wmv)
In an R&D project contracted to Shun Tak Ferries
in Hong Kong,
Unistel Technologies PTY Ltd
of the University of
Stellenbosch organised a Hysuwac
foil system that was designed by FASTcc
for a 45m Tricat ferry with 212t.
Built by FBM Marine Ltd, propelled by twin Taurus 60M Gas turbines driven by KaMeWa
Waterjets 90S 11 (900mm internal diameter), which were allowed a maximum power output
of only 3600 kW each (for extended maintenance cycles!).
Model tests in the towing tank at the University of Stellenbosch, RSA indicated that
the 41 knot ferry should reach top speeds of over 50 knots due to the foil system with
about 20% fuel consumption improvement.
