Resource Workshop
www.eera-set.eu
Prioritised Synergies Prioritised Gaps 1. Metadata exchange Collaboration; data sharing; modelling
validation; geo-spatial variation; measurement and instrumentation.
2. Sea state analysis Bi-modality; extremes; parameter
relationships; variability between sites.
3. Wave/tidal current interactions: Use of HF radar systems; site-specific
impacts of currents on wave resource.
1. Design conditions Device interaction effects; extremes:
turbulence, waves, currents, winds; sea state parameterisations.
2. Array and farm modelling Local impacts of wave and tidal farms;
inter-farm impacts; regional impacts – will significant development in one region affect the available resource in another?
3. Calculating the extractable resource Development of a standardised
methodology to calculate the extractable resource from the total available resource.
Resource Workshop
Resulting collaborative work:
• Collaborators: UK, Ireland, Spain, Portugal
• Synergy areas: Sea-state analysis • Gap areas: Calculating the
extractable resource • Output: A collaborative journal

WT 2: Devices Technology WT 3: Deployment and operations
Introduction During the kick-off meeting of the Ocean JP in June, it was agreed the organisation of a combined workshop dealing with the Research Themes 2 (Devices and Technology) and 3 (Deployment and Operations) This combined workshop was organised in December 2011 hosted by TECNALIA, who is one of the coordinators of these research themes
www.eera-set.eu
Introduction At the outset of the Ocean JP, a number of sub-topics have been identified as key long term research objectives within each of the six key research themes. For the Research Themes 2 and 3, these are
www.eera-set.eu
RT2 – Devices and Technology Sub-topics
RT3 – Deployment and Operations Subtopics
•Overall Design Optimisation •Power Take Off •Combined Platforms •Moorings and Foundations: Interactions with devices •Advanced Control •Dynamic Structural Response •Performance assessment methods
•Reliability •Bio-fouling and Corrosion/Ageing •Farm Planning •Infrastructure and Supply Chain •Moorings and Foundations with regards to farm •Power Conditioning and Network integration •Novel installation, servicing and recovery methods
Workshop objectives The workshop had 4 principal objectives: • Act as a forum to communicate the research which is
being carried out within different countries. • Identify areas where overlap exists between research
taking place in different countries and therefore where synergies and opportunities for collaboration exist.
• Identify areas where gaps exist to be considered in future joint activities.
• To agree the preparation of joint research papers in topics of both research themes.
