Marine renewables team within the International Electrotechnical Commission (IEC) has released the technical specification for loads measurements in full-scale marine energy converters.

The IEC project team, PT 62600-3, published the first committee draft for the measurement of mechanical loads on full scale marine energy converters, like wave, tidal or river energy devices.

The international technical specification is relevant for technology developers, test laboratories – including open water test sites – and certification bodies, according to the team.

The publication describes the measurements to be performed for all kinds of marine energy converter types. According to the developers, the draft – developed by the IEC Technical Committee 114 which is in charge of marine energy – includes a detailed description on how and where to measure loads especially for bladed turbines.

Accurate and reliable loads data in combination with measured energy flux – wave, tidal or other – can be used to validate load simulation models, which in turn can be used to optimize blade design, the expert team said.

The technical specification, released for commenting until March 8, 2019 – also provides instructions for full-scale laboratory rotor blade testing.

The development of this technical specification has been led by Dutch Marine Energy Centre (DMEC), and supported by the MET-CERTIFIED project.

Funded by the European Interreg 2 Seas program and co-financed by the European Fund for Regional Development (ERFD), the MET-CERTIFIED project aims to increase the adoption of insurable and therefore bankable marine energy projects through the development of internationally recognized standards and certification schemes for the sector.

The project is also financially supported by the Ministry of Economic Affairs in the Netherlands, Province of South-Holland and North-Holland and the Belgian Province of West Flanders.

Offshore Energy Exhibition and Conference (OEEC) 2019

Offshore Energy Exhibition and Conference (OEEC) is where the energy transition takes place. It is Europe’s leading gathering of the entire offshore energy industry and your opportunity to network with highly qualified experts and professionals across global markets.

For more than 12 years OEEC is unique in bringing together the offshore energy industry sectors oil & gas, offshore wind and marine energy. More than 550 exhibitors from around the world present their newest services, projects and innovative products. On top of this OEEC presents international trade missions, pavilions, exclusive network lounges of the OEEC member club, the Startup Zone, matchmaking areas, the Stage and networking drinks. Approximately 12,000 professionals will visit the exhibition, take part in strategic discussions, immersive technical conference sessions focusing on the future and technical developments in the industry. Three days of networking and together shaping the future of energy.

So the question is not if but how you will be participating at Offshore Energy 2019.
