Hull Vane's fuel-saving system showcased for the first time at Euronaval 2016
Euronaval 2016 is one of the leading international trade shows for maritime security, safety and naval defense. This year, The Dutch company Hull Vane is unveiling a proven solution to reduce naval surface ships’ fuel consumption by 10 to 15% and improve their seakeeping.

Recent research has shown a significant improvement of the comfort, safety and operability in waves of OPVs, corvettes and frigates. The reduction in propulsion power, propeller loading and stern wave also has a positive influence on the ship’s underwater noise signature. Helicopter and drone operations are made safer by reducing the vertical and horizontal accelerations of the helo-deck when sailing in waves.

The Hull Vane system is a fixed hydrofoil positioned below or behind a ship's transom. It modifies the vessel's stern wave pattern and generates hydrodynamic lift with a forward component. This reduces the siph's resistance and dampens the pitching, heaving, rolling, and yawing.

This system is particularly effective when used on relatively high speed vessels, or expressed in naval terms at Froud numbers between 0.2 and 0.7. For a 50 m vessel, this equates to a speed range between 8 and 30 knots. Similarly, for 100 m and 200 m vessels, this equates to minimum speed of 12 and 17 knots respectively.

Ideal candidates for a Hull Vane include coastguard and naval vessels, ferries, cruise ships, supplys vessels and motor yachts.

Hull Vane presents several case studies at the stand, focusing on the improved efficiency and seakeeping effect of the Hull Vane. One of these concerns a CFD study on the DTMB5415, a generic frigate-type hull form, whilst another one is about the effects of the Hull Vane on the 108 meter Holland Class OPVs of the Royal Netherlands Navy. A comparison between the effects of a Hull Vane, trim wedges and interceptors on a 50 m OPV hull form will also be shown.
