The Hull Vane® is a patented fixed foil located below or behind a ship''s transom. The Hull Vane influences the stern wave pattern and creates hydrodynamic lift, which is partially oriented forward.
This results in a reduction in of the ship’s resistance. The performance of the Hull Vane® depends on the ship’s length, speed and hull shape in the aft sections, and ranges from 5% to 15% for suitable ships. In specific cases, fuel savings can be up to 20%.
Hull Vane® – Tech Talk
The fuel-saving effect of the Hull Vane® is due to four distinct aspects:
- Improved fuel economy
- Reduced emissions
- Greater range
- Reduced installed propulsion power for same top speed
- Reduced wave formation
- Improved seakeeping – reduced pitching, rolling and yawing
- Zero moving parts
- Proven technology
- New build or retrofit
While participating in a tender for a new patrol boat for the Port of Rotterdam, we contracted Van Oossanen for the naval architecture. Based on the operational profile of the boat, they suggested a Hull Vane® to be integrated in the design, which we did. We won the tender on lowest life-cycle costs and minimal wave-making. Later on, model tests at Marin confirmed the CFD calculations: a reduction in fuel consumption of 22 to 25% over the entire useful speed range (10 to 19 knots), and a significant reduction in waves generated by the boat
