Marine Energy

Project Aims

  • Help enable & build sustainable marine energy sector in Wales
  • Evaluate & enhance technologies to recover energy from waves, tidal streams & tidal ranges around Wales
  • Examine the effects of devices on the environment (e.g. seabed communities, sediment transport & marine wildlife)
  • Examine effects of the environment on the devices

LCRI Marine is a collaboration of all the leading academic marine institutions in Wales. It provides the independent and world-class research essential to move the marine renewable energy industry forward. Marine energy is a zero carbon energy source in which the UK presently has the lead. Marine renewable energy includes;


  • Tidal range which uses tidal barrage or lagoon technologies to harness the rise and fall of the tide

  • Tidal stream which uses underwater turbines to exploit fast flowing currents in the water

  • Wave power which is gathered by equipment placed primarily offshore to gather energy carried in waves

Research Areas

  • Data acquisition on marine mammal & cetacean behaviour, fish populations, water quality effects of devices on fish movements, & hydrodynamics, design & testing
  • Near-field modelling: of environmental effects, device life, location & positioning, blade performance
  • Far-field modelling: hydro-environmental modelling, long-term effects of climate change on devices, coastal processes
  • Implementation: investigating public understanding, device siting & economics

Case Study: Knowledge Exchange Workshop – Three Cliffs Coffee Shop
LCRI Marine held a marine mammal identification and surveying training day in Swansea, to help inform the surrounding community of the local harbour porpoise population. LCRI Marine’s Judith Oakley from Swansea Metropolitan University (SMU) held a knowledge exchange workshop in collaboration wi... (read more)
Case Study: Milford Haven Port Authority
LCRI Marine studied the marine energy resource with Milford Haven Port Authority in Pembrokeshire, to help identify suitable sites for marine renewable energy projects. LCRI Marine’s Iain Fairley from Swansea University working in collaboration with the Milford Haven Port Authority (MHPA) under... (read more)
Case Study: Tidal Energy Ltd
LCRI Marine studied the environmental effects of acoustic interaction between marine wildlife and a proposed marine renewable energy device at Ramsey Sound in Pembrokeshire. LCRI Marine’s Merin Broudic from Swansea University working in collaboration with Tidal Energy Ltd undertook a project to... (read more)
Case Study: Titan Environmental Surveys
LCRI Marine formed a knowledge exchange relationship with Titan Environmental Surveys in Bridgend, to help position them for future opportunities in the marine renewable energy supply chain. LCRI Marine’s Paul Evans from Cardiff University working in collaboration with Titan Environmental Surve... (read more)
