STX Awarded Contract for New PV90 Design

VARD Marine

STX Canada Marine has been awarded a contract by Babcock UK subsidiary Devonport Naval Dockyard, to design the next-generation offshore patrol vessel (OPV) for the Irish Naval Service (INS).

The new OPV will be a lengthened version of the current STXM PV80 design of which two vessels, L.E. Roisin and L.E. Niamh were delivered by Appledore Shipbuilding in 2000 and 2001.

The tender process for the new vessels began in 2008 and it was late summer of 2010 that Babcock has reached an agreement with the Irish Defence Department to deliver two new vessels to enhance the INS fleet. The success of the existing vessels, and in particular the high-quality construction from Appledore Shipyard, were clearly an influencing factor in selecting Babcock and STXM for the contract.

The new PV90 vessels will maintain the overall configuration of the PV80 but will be increased in length by more than 10m and have an additional 0.60m in depth to provide greater operational capability for the rough waters patrolled by the INS. The maximum speed of the vessels will be increased to 23kn and the addition of a power input on each gearbox will permit more efficient low-speed operation without having to run the main propulsion system at very low power levels. STXM will provide the classification design of the vessel and looks forward to continuing the excellent relationship with Appledore Shipbuilders from the previous contract in the late 1990s.
