EU Interreg Tiger Project and ORE Catapult
Yarmouth
As a showcase for the EU, QED designed, developed, built, deployed, and thoroughly tested a self-deploying, submersible tidal system as part of its EU Interreg Tiger project, in collaboration with ORE Catapult. This end-to-end project demonstrated the ease and cost-effectiveness of deploying tidal systems globally. The Tidal Stream Industry Energiser Project (TIGER) is a €48.4m initiative, with €32.05m (66%) funded by the European Regional Development Fund through the Interreg France (Channel) England Programme. TIGER focuses on low-carbon technologies and is managed by Norfolk County Council, supporting cross-border collaboration between the UK and France. The project tested and demonstrated new technologies, including QED Naval's Subhub and turbines, which led to improved designs for enhanced performance and reduced costs in tidal energy generation.
QED’s self-deploying turbines reduced operational costs by as much as 60% and improved turbine yields by over 40%, with systems and designs undergoing independent due diligence and testing involving ORE Catapult. The system can operate at an estimated 300 kW (depending on water flow) and is completely net zero in terms of CO₂ impact, as it is 100% renewable and does not produce any greenhouse gases.
Subhub Tidal Platform is a submersible, gravity-based foundation used to support an array of tidal turbines through life. It integrates the whole tidal energy plant at the quayside, where everything is commissioned and tested in a safe, accessible environment. Subhub is then used as a transportation barge to deploy tidal equipment straight to site using commonly available, low cost, harbour tugs etc. In a single offshore operation the Subhub, along with turbines, is installed in a quick and easy ballasting process, using its unique submerged stability characteristics to install itself on the seabed. It then de-ballasts further to adopt its required operating condition. The hydrodynamically designed hull form accelerates flows to tidal turbines, to extract on average 47% more energy from sites. Maintenance and decommissioning is a simple case of deballasting Subhub to bring it back to the surface.
