New Generation Maritime Affairs Patrol Vessel (PAM): From Contract Signature to Steel Cutting Ceremony
In December 2024, the tender for the New Generation Maritime Affairs Patrol Vessel (PAM) project was awarded, officially announced in January 2025. This initiative, characterized by its innovative wind-assisted propulsion, reached a critical milestone with the steel cutting ceremony held on September 18. This event signifies the shift from the design phase to the tangible construction of this advanced naval asset.
Technical Advances in 2025
The naval architects and marine engineers at MAURIC have successfully completed a comprehensive arrangement study for the vessel. This study includes an optimization loop to enhance sail positioning and finalize the development of both active and passive stabilization systems. Through meticulous seakeeping calculations, the design team optimized the anti-roll tank and integrated effective active fin stabilizers.
Additionally, advancements in computational fluid dynamics (CFD) have enabled the refinement of the bulbous bow, enhancing the vessel’s hydrodynamic efficiency. CFD studies have successfully reduced water resistance and established parameters for the active trim control system, achieving a hybrid cruising speed of 10 knots and a maximum speed exceeding 18 knots. This performance is pivotal in ensuring the vessel’s energy efficiency while minimizing its environmental impact.
Progressing Construction
The design phase has meticulously outlined an assembly sequence divided into eight modular blocks. Illustrated in an accompanying graphic is the structural outline of the first block, strategically positioned in the forward section of the hull. Preparations for cutting this initial block are underway at the Socarenam facility in Boulogne-sur-Mer. The commencement of steel cutting marks a definitive start to fabrication, ensuring adherence to the anticipated construction timeline, with delivery scheduled for the latter half of 2027.
This initiative underscores the exceptional capabilities of French naval engineering, presenting tailored maritime solutions that marry operational efficiency with ecological responsibility.
