Since 2013, Piriou and Naval Group have been partners in the Kership joint venture set up to market a variety of vessels for maritime security and naval missions. The range includes offshore patrol vessels, from 45 to 90m in length, suitable for blue water and long-range operations. All feature a panoramic (360°) bridge and the Polaris combat management system developed by Naval Group to manage the ship’s sensors, display the tactical situation and provide communications resources for missions as part of a multinational force.L’AdroitThe OPV 90 is the largest in the range. The prototype, L’Adroit, has been in operation since 2012 and was used by the French Navy for a variety of missions up until mid-2018. It was deployed in the Indian Ocean on anti-piracy, counter-terrorism and trafficking interdiction operations, and conducted fisheries policing and illegal immigration prevention missions in the Mediterranean. It also took a company of commandos to Yemen where they evacuated foreign residents and exfiltrated civilians.With an at-sea availability of 220 days per year, the OPV 90 is designed for extended ocean patrol and surveillance missions and protection against asymmetric and other threats. One of the design’s distinguishing features is the high panoramic bridge surmounted by a single enclosed mast housing the radars and other sensors. The bridge houses the platform management consoles, the flight ops console and the operations area. Alternatively, the operations area can be located in a separate enclosed space below deck.The spacious flight deck can accommodate a 10t helicopter and the hangar a 5t machine along with a UAV. The L’Adroit was the first European vessel to deploy a UAV (a Schiebel S-100 Camcopter) on operational missions. With accommodation for 27 passengers or commandos in addition to a crew of 32, the OPV 90 can be equipped with R-ESM and C-ESM equipment and is ideal for special forces operations. The design includes a pair of stern ramps for the quick launch and recovery of two 9m RHIBs. In addition to conventional weapons, the L’Adroit is equipped with two non-lethal water cannons that can be remotely controlled from the bridge.New rangeBetween 2016 and 2018, Kership upgraded its range with new 45, 52, 58, 70 and 75-metre types. Like the OPV 90, these models are fast, rugged, economical and easy to operate and maintain. The designs combine a steel hull and an aluminium superstructure. Depending on client needs, these OPVs can be fitted with a variety of equipment and weapons ranging from light remotely-operated guns to a 76mm gun turret, anti-ship missiles, and even air defence systems, not to mention an R-ESM and C-ESM suite and two decoy launchers. Their flight decks can accommodate a 5 to 10t helicopter or drones. Standard fits also include RHIBs and modular compartments that can be reconfigured for different missions.More importantly, they boast speeds of over 35 knots and feature C-Sharp (Combined-Speed Hull with All-Round Performance) hullforms based on an innovative patented concept developed in association with the LHEEA hydrodynamics laboratory in Nantes. C-Sharp hulls offer high performance at all speeds. Compared to hulls optimised primarily for pursuit speeds, C-Sharp vessels offer 10 to 30% greater range at patrol and transit speeds. They also offer better acceleration in rough seas and improved platform stability for RHIB deployment and recovery. Kership is also applying the concept to new-generation coastal patrol vessels.
