4 International track record in wave and tidal We have the experience. Owner s engineer South West Regional Development Agency Cornwall, England 30MW Project management, overall design and full owner s engineer Wave Hub is described as an electrical socket on the seabed connected to the national grid via a subsea cable. The scope of the project was considerable, taking in responsibility for the overall design of the system, including subsea cables, connections, transformers, grid connections, and procurement, fabrication management, and project management on behalf of the SWRDA. The development is a groundbreaking wave energy project off the south west coast of England, approximately 10 miles from the coast of Cornwall. With water depths ranging between 48m and 58m, the site is considered to have one of the best wave climates in Europe. The scheme is jointly funded by the government, the South West Regional Development Agency (SWRDA) and the EU, and will be the UK s first offshore facility for demonstrating a commercial-scale wave power plant. The completion of the 30m project will result in it being the world s largest wave energy farm, with an initial capacity of up to 20MW and a possibility of this being upgradeable to 48MW. In addition to the energy produced by the project, it is expected to provide important technological research outcomes for the rest of the industry, particularly with regard to larger scale projects, and foster local expertise and growth in the renewable energy industry in the south west. Foundation design OpenHydro Group Ltd Europe and North America Technical advisor Working with OpenHydro Group Ltd. to advance its world leading tidal energy technology, we provided finite element modelling to simulate penetration of the turbine foundation into the rock seabed and predict performance under lateral loads. Our role investigated: Rock modelling reviewing and developing rock and soil models for FEA analysis, based on existing models Vertical penetration of the foundation footing, involving the simulated deployment of larger tidal devices and foundations in different subsea conditions Lateral holding capacity, including mechanisms to resist the overturning moment post-penetration, lateral holding capacity checks, and potential ploughing actions and sliding resistance Failure consequences, from rock failure mechanisms to the consequences of excessive lateral load.

5 Technical due diligence Arbuthnot Securities UK 1MW Technical due diligence Our specialist team performed an independent technical assessment of REH s energy portfolio on behalf of investment bank, Arbuthnot Securities. The scope of this assessment included REH s biogas and wind projects and assets, as well as the CETO wave powered desalination and electricity generation technology. Site accessibility Scottish Power Pentland Firth, Scotland Site accessibility study A site accessibility study was performed to investigate wave propagation into the Pentland Firth. The study involved investigating available bathymetric data sources, and investigating the swell refraction angles of waves arriving at the mouth of the Firth. Pioneering research As part of an internal research and technology development programme, Wood Group Kenny conducted an in depth study on tidal array energy yield, based on real device data and with input from marine energy suppliers. Particular focus was placed on the effects of wake and shield to demonstrate the capability for complex analysis related to the optimisation of an array. By applying the findings of this rigorous research to existing knowledge, we are set to enable significant further development in the accuracy of yield predictions for tidal farms. We foresee significant benefits for the industry and our potential clients, including: A capability of modelling and analysing the wake and shielding associated with tidal devices within an array Knowledge of key factors influencing wake and shielding, and an ability to quantify the effects on individual turbines or an array The ability to apply an approach to accurately predict energy yield from tidal devices within an array. Cable stability Meygen Consortium Pentland Firth, Scotland Front end engineering design Meygen s ambitious tidal turbine project will see 400 turbines installed in the Pentland Firth by We investigated a number of cable array concepts. In this challenging environment, with surface currents of up to 4.9m/s and strong swell, our scope was to: Undertake a preliminary desktop route selection study for a typical seabed route under GIS Generate a typical profile of the naturally occurring channels in the rock Perform an initial stability analysis (to DNV RP F109) Complete a CFD simulation of the boundary layer (within a typical seabed valley) Re-run stability analysis using CFD results Assess cable protection measures including rock dump, articulated pipe and concrete mattresses Provide recommendations for further work. With the results of our CFD analysis, Meygen obtained proof of the occurrence of the hydrodynamic shielding in the natural seabed channels.
