Press Release: Improving the reliability of wave & tidal energy convertors

 Marine-i Delivery Partner, Offshore Renewable Energy (ORE) Catapult, will be running an interactive  Discovery Room session on Friday 13th April 2018 at Chi Gallos, Hayle, Cornwall.

Wave energy device developers will be introduced to the latest techniques set to radically improve the reliability of wave energy farms.

ORE Catapult will share insights from the second phase of an international collaborative research project named Reliability in a Sea of Risk (RiaSoR), which is now underway and designed to improve the reliability of wave and tidal energy convertors.

By reducing associated risks and enhancing reliability, the project aims to encourage increased investment in the marine energy industry by both the public and private sector.

Building on the success of Phase 1 of the RiaSoR project, which developed a theoretical reliability assessment framework for wave (and tidal) energy convertors, Phase 2 aims to enable developers to validate their findings and establish a practical, condition-based monitoring platform to prepare for future arrays, where big data handling and processing will be vital to drive down operational expenditure.

Marine energy devices operate in harsh environments but still need to perform reliably and produce an expected amount of energy, which gives rise to huge engineering challenges.

Funded through the OceanERANET initiative and led by the Research Institute of Sweden (RISE), RiaSoR2 brings together the European Marine Energy Centre (EMEC), the Offshore Renewable Energy (ORE) Catapult, Alkit Communications, Synective Labs, CorPower Ocean, Waves4Power and OceanHarvesting to offer a comprehensive suite of testing methodologies to wave and tidal developers that will enable a systematic approach to achieve optimal reliability and performance, while minimising cost and time-to-market.

The findings from this project will be disseminated to other WEC and TEC developers, and the wider industry through future Industry Advisory Group meetings and training for device developers

Simon Cheeseman of ORE Catapult, one of the Marine-i partners, says:

“Wave devices will be working in some of the harshest seas in the world. Survivability and reliability are paramount. RiaSoR 2 is about establishing a methodology and testing programme so we can gather data between device installation through mean time to failure. The instrumentation, condition monitoring methodology will use Variation Mode and Effect Analysis methodology which is standard practice in more mature sectors such as the automotive and aerospace industry. This will be adapted in the RiaSoR project for the ocean energy sector and will provide valuable insight into prototype design development. It is important that we share project insights with the wave energy community and use their feedback to maximise the benefit and impact from the project.”

ORE Catapult’s RiaSoR engineer, Dr Othmane El Mountassir, will be leading the event. He will be supported by Dr Tessa Gordelier, research Fellow, from Marine-i Delivery Partner University of Exeter. Tessa will discuss condition monitoring of offshore mooring systems for wave devices.

Companies interested in participating in this event, or wishing to know more, should contact Simon Cheeseman on 07834 737 250 or email simon.cheeseman@ore.catapult.org.uk

Delegates will be able to participate in person or join the session via Skype.
