Wind-assisted patrol vessel begins construction

The New Generation Maritime Affairs Patrol Vessel (PAM), featuring wind-assisted propulsion, has officially entered its construction phase with the first steel cutting on 18 September 2025.

This milestone marks the shift from design to assembly, following the project’s tender award in December 2024 and formal announcement in January 2025.

Developed by France-based naval architect Mauric, the vessel integrates advanced technologies to enhance operational efficiency and reduce environmental impact. Naval architects and marine engineers have completed the vessel’s detailed design, including the placement of wind-assist systems and the integration of stabilisation technologies.

Sea-keeping simulations guided the development of anti-roll tanks and active fin stabilisers, while computational fluid dynamics studies optimised the hydrodynamic shape of the bulbous bow and defined an active trim control system.

The vessel’s hybrid propulsion system combines diesel-electric power with wind assistance, enabling a cruising speed of 10 knots and a top speed exceeding 18 knots.

Construction is structured around eight modular blocks. The first block, located in the forward hull section, is now ready for cutting at Socarenam’s shipyard in Boulogne-sur-Mer. Delivery remains scheduled for the second half of 2027.

The 53.7-metre vessel features a steel hull and aluminium superstructure. It supports a crew of 16 and can accommodate four special forces personnel, with 12 days of autonomy and up to 200 days of operation per year.

Primarily operating in the Bay of Biscay, the PAM will conduct missions including maritime surveillance, fisheries control, environmental monitoring, search and rescue, and regulatory enforcement.
