#ferries - Brittany Ferries Cork-Roscoff cruise-ferry Pont-Aven began today its first sailing in 2019 on the seasonal route and will save energy and reduce fuel consumption thanks to the installation of two innovative devices on the ship's propellers.

Wärtsilä‘s EnergoProfin system is a small sub-prop, which is attached to the main propeller helmet, helping improve propulsion in water. Two of these devices were installed during the ship’s dry dock in December 2018. As a consequence fuel consumption and emissions have been cut by around 2% on every crossing.

This project is a small – but significant – step and it comes as part of a range of studies initiated through Brittany Ferries’ Research and Development program. But, as Vincent Coquen, Head of R&D, Energy and Environment for the company, explains, it is not just a question of developing practical and technical solutions for today such as the propellers on Pont-Aven.

“Sustainable development means looking to the future and studying innovative projects and technologies that could be used in either the short or longer term,” he said.

For the past two years, Brittany Ferries has partnered with CEA Tech in France. Several projects are underway, including the development of a long-range broadband link that would use land-based transmitters to obviate the use of satellite-at-sea. A second study focuses on hybrid energy solutions for Cap Finistère, Brittany Ferries cruise-ferry that sails from the UK to Spain. The last is exploring the long-term implementation of fuel cells for powering certain of the ship's on-board systems.

Brittany Ferries is also looking at the potential for wind energy. Flettner rotors, traction wings, or modern sails are at different stages of development, but could significantly reduce ship fuel consumption and therefore emissions.

“Of course, we must be cautious, checking the feasibility of integrating these technologies on board our ships, in terms of safety, reliability and profitability,” added Vincent Coquen. “But I am convinced that they will have a significant role in the equation that ship-owners must solve to achieve the zero emissions ship.”
