The ReDAPT project purpose is to demonstrate the performance of the tidal generators under different operational conditions. Demonstrating a new reliable turbine designs and by providing performance information, the project aims to increase public and industry confidence in tidal turbine technologies.
The ReDAPT project has seen an innovative 1MW buoyant tidal generator installed at the European Marine Energy Centre (EMEC) in Orkney in January 2013. With an ETI investment of £12.6m, the project involves Alstom, E.ON, EDF, DNV GL, Plymouth Marine Laboratory (PML), EMEC and the University of Edinburgh. Currently a 1MW tidal generator has been installed at EMEC test site which has been producing electricity in testing. Further details.

The PerAWaT project was launched in October 2009 with an initial investment of £8m by Energy Technologies Institute (ETI). The project aims to reduce the levels of uncertainty in predicting energy associated to wave and tidal stream farms by producing validated software tools.
Marine renewable energy is still in an infant stage of development and the effect of energy extraction devices on one another and with the surrounding environment is still not very clear, which leads to a huge uncertainty on the levels of energy generation. The PerAWaT project aims to increase the market confidence in Marine energy by quantifying and reducing these uncertainties. Further information.

The integrating COASTal Sediment Systems (iCOASST) project will help forecast what the UK’s coastline will look like in the future, up to 100 years’ time. A number of UK universities, research laboratories and leading consultants are working together to improve the capability of predicting long-term and regional scale change on the coastlines and in estuaries in the UK. This will provide the starting point for an open source community model of integrated coastal sediment systems.
The iCOASST project is funded by the Natural Environment Research Council (NERC) and is partnered by the Environment Agency (EA). The iCOASST objectives are associated with the four deliverables of the iCOASST project:
- Deliverable 1: To develop a new coastal systems modelling framework that integrates diverse knowledge of coastal processes and behaviour, forming the basis for new scientific understanding of coastal behaviour at the mesoscale (10-100 years and 10-100 km).
- Deliverable 2: To develop and integrate behavioural geomorphic models in order to provide mesoscale predictions of coastal change and new insights into emergent coastal behaviour.
- Deliverable 3: To test, validate and demonstrate the modelling methods developed in Deliverables 1 and 2 in two contrasting coastal regions.
- Deliverable 4: To ensure that the research has genuine and lasting impact upon the scientific and practitioner communities.

EXtreme Loading of Marine Energy Devices due to Waves, Current, Flotsam and Mammal Impact (X-MED) aims to identify the design criteria for sea states with waves and currents for tidal turbines. This is done by both modelling and by experiments to study the extreme loading on tidal turbines due to turbulence, large scale horizontal eddy structures and superimposed waves. The project also looks at the impact of flotsam and marine mammals and sharks on tidal stream turbines.
It is estimated that by 2020 renewable energy will contribute to about 30% of the UK electricity needs. Within the context pf renewable energy, tidal stream turbines are a more mature technology than other counterpart wave energy devices. There is also a fast growing confidence in the performance of these devices, however, knowledge of extreme loading is still not fully understood with some levels of uncertainty. Further information.

Within the broader context of renewable energy the potential of wave energy his high. However wave energy conversion requires a step change in power output per unit cost which hiders it from becoming commercially viable. Step change for Wave Energy Conversion through floating multi-body multi-mode systems in swell (StepWEC) aims to explore wave energy concepts with multi-mode and multi-body response using simplified nonlinear time stepping modelling.
The project also aims at assessing the performance of arrays in intermediate-to-deep water and to experimentally measure interaction of directional random waves, swells and currents. Further information.
