Generally, government owned vessels, particularly ones engaged in law enforcement, are seemingly last in line when it comes to fuel efficiency. Not so in France, as the Directorate General for Maritime Affairs, Fisheries and Aquaculture (DGAMPA), in late 2024 sealed the deal and commissioned the SOCARENAM-MAURIC consortium to design and build an offshore patrol vessel (OPV) which combines hybrid propulsion and wind sails, among other energy saving/emission reduction enhancements.

According to the government agency, “this order is part of a dual strategic approach: modernizing the fleet dedicated to the control and surveillance system (DCS) and the commitment towards environmental exemplarity of DGAMPA vessels.

The wind-assisted propulsion solution, combined with diesel-electric hybrid propulsion and IMO TIER III compliant engines, are designed to position the vessel “at the forefront of maritime ecological transition,” wrote DGAMPA.

As with all vessel designs, there is not a silver-bullet solution to increased efficiency, and this vessel will also have a hull design optimized through computational fluid dynamics, enhanced insulation with optimized energy management, photovoltaic panels, and an active trim control system.

The 54m OPV is…
