Benefits

Higher top speed

A reduced resistance with the same power means you get more speed out of your ship. The improved sailing characteristics are immediately noticeable to those at the helm.

Longer range

The range is larger due to the lower fuel consumption. Or the same range can be covered at a higher transit speed. An important naval capability!

Improved seakeeping
The Hull Vane® dampens the ship’s motions in waves. This means safer helicopter and drone landings, safer daughter craft launch and recovery, improved performance of radars and weapon systems, and less tiring conditions for the crew.
Less noise

The Hull Vane® ensures noise reduction because the propellers are less loaded and the main engines work less hard for the same speed.  The improved wake also reduces the noise of the stern wave, a main contributor to exterior and underwater noise.

Low wash

The stern wave of a ship is considerably reduced by the Hull Vane®, making the ship less visible to other ships, aircraft, drones or satellites.

Win tenders
By reducing life cycle costs, Hull Vane® improves the bid package and increases the chance to win public tenders. Several tenders for patrol vessels have been won with Hull Vane® a part of the scope.
Reduce build costs
When less installed power is needed to achieve the required top speed, cost savings are made on engine power, exhausts systems, cooling systems, etc. On patrol vessels, corvettes and frigates, the cost of the Hull Vane® is much less than the costs it reduces.
Innovate
Hull Vane® is a proven innovation to improve ships’ performance and seakeeping, with a very low risk to the shipbuilder.
Readiness for future transition

Reducing the resistance of a ship today, makes it easier to do the energy transition tomorrow. The ship design becomes more future-proof.

Added value design
Clients appreciate an optimised design with lower life cycle costs. Several public tenders have been won by integrating the Hull Vane® benefits in the design from the start.
Space savings

For a given top speed and range, the naval architect can use smaller main engines, exhaust systems, engine room ventilation and smaller fuel tanks. This results in more useful space on board, and less build cost.

Custom Designed, Custom Built

Just like a bulbous bow, each Hull Vane® is different and custom designed for a specific ship. An optimisation of the Hull Vane® using Computational Fluid Dynamics (CFD) is the starting point. Such a Hull Vane® study indicates how much the ship’s resistance is reduced with the addition of a Hull Vane® – either for a single speed or for a wider operational profile.

Based on the results of this study, a cost-benefit analysis can be made and a go or no-go can be given for the further development of a Hull Vane® for this ship. In the following phase, we conduct a Finite Element Analysis and vibration analysis to ensure sufficient strength of the Hull Vane® for a lifetime of trouble-free operations. Hull Vane BV builds the Hull Vane® with certified welders and a high degree of finish and accuracy.
