At her recent dry-dock at Remontowa, Gdańsk, the hull of Brittany Ferries’ PONT-AVEN was lengthened by three metres at the stern waterline. This is often referred to as a duck-tail.
The purpose of the modification is to improve the hydrodynamic performance of the vessel. This will reduce the drag on her hull, reducing fuel consumption by around 10% and therefore emissions. The work follows analysis by the Chantiers de l’Atlantique design office where various ideas were looked at, followed by tests on the favoured concept using a 7-metre scale model of the PONT-AVEN
Additionally, Brittany Ferries is working with Wärtsilä to examine improving the propeller design of PONT-AVEN. This could lead to a further reduction in fuel consumption of around 5%.
Meanwhile, Bureau Veritas Solutions Marine & Offshore (BV Solutions M&O) has developed and delivered a ‘Fleet Energy and Emissions Forecast‘ tool to Brittany Ferries. The tool enables the ferry company’s onboard teams to plan for optimised and efficient operations, thereby reducing fuel consumption, emissions, and costs.
