The Power, Propulsion and Auxiliaries (PPA) Team, which is part of the ships operating centre within Defence Equipment Support (DES) provides global support to the Royal Navy. PPA has set up a Framework agreement to provide systems spares to Royal Naval Platforms through an established set of suppliers. There is a possibility that during the life of the proposed contract that the size of HM Naval Fleet may increase or decrease. The support contract took the form of a Framework arrangement and has been awarded under DSPCR 2011 regulations. Call-Off contracts were awarded to 23 suppliers via call-off competitions. Mini-Competitions are held throughout the life of the framework agreement. This mini-competition was for the provision of SPA689. Call-off price withheld due to commercial sensitivities and the ongoing competitive nature of the Framework.
