The EU-backed Reliability in a Sea of Risk (RiaSoR) project has published guidance on the assessment of marine device reliability.

The ‘Reliability Guidance for Marine Energy Converters’ report harnesses variation mode and effect analysis (VEMA) from the automotive and aerospace industries to the wave and energy sector.

The reliability methodology looks at the design criteria for marine energy converters with the different phases of VMEA explained in detail.

The guidance was developed by SP Technical Research Institute of Sweden, in association with the European Marine Energy Centre and Offshore Renewable Energy Catapult.

The guidance document also provides case studies looking at structural, electrical and mooring/foundation elements of devices.

There is also a short reference guide and Excel template provided to support future application of the tool.

The RiaSoR project is funded by the Ocean Energy European Research Area Network in association with Scottish Enterprise, InnovateUK and Swedish Energy Agency.

The report is available to download from RiaSoR’s website
