LORC tests and demonstrates technology for harvesting renewable energy offshore

Latest News

Meeting industry’s needs for environmental testing of large components for offshore use is now one step closer with the ordering of a climatic chamber for a new LORC test centre.

  1. Sustainability is hardheaded business. In order to lower the Cost of Energy, more and better testing is needed. The world’s largest and most advanced test bench for the future 10MW wind turbines is underway. LORC – Lindoe Offshore Renewables Center and Risoe DTU are the driving force behind the project which also includes resources from a number of private enterprises.
  2. Collaboration and the sharing of experiences can take wind farms to the next level, according to Helge Gravesen, technical project leader of the Carbon Trust’s Offshore Wind Accelerator (OWA) foundations competition, Stage 1. He has experienced the benefits of cooperation in a sector that is normally marked by protectionism.
  3. With a maximum of work performed on shore and with installation by unmanned barge, this foundation concept leads to improved safety and quality concrete. Looking into it makes perfect sense. GBF® project manager Kevin Bennett explains the concept.
  4. The suction bucket is a newcomer among support structures, but it may represent one of the solutions of the future to cutting costs offshore. Easy installation is the key – no drills or hammers are necessary, just apply vacuum.
  5. Read it here:
  6. Faster installation and fewer installation manoeuvres, using less steel and fewer components, all add up to an estimated 10% decrease in costs: this foundation concept has a lot in its favour compared to a four legged reference jacket, explains engineer Rudy Hall
  7. Self installing wind turbine by Anne Korsgaard and Karsten Prinds
    It resembles a tripod, but is asymmetric and with one leg missing. That is because the installation had to be made easier, Project Engineer Thijs Visser explains.
  8. Deep waters are yet to be conquered by Mads Kromann-Larsen and Karsten Prinds
    ‘Offshore’ is still very much ‘near shore’, and deep waters are still not deeper than the length of a blade. This is shown by an analysis of the world’s producing wind farms.
  9. Managing the installation of a wind farm takes a lot of pulling the right strings at the right time. Foundations project manager Rasmus Miller tells about his constant focus on optimization.
  10. An ambitious attempt to put turbines into deep water is ongoing in Norway. Entering its second winter, the Hywind project has made its owners hungry for more.
  11. A new industrial facility has entered the expanding market of offshore renewables. And not just any facility: One of Europe’s largest shipyards, Odense Steel Shipyard, is now gradually turning into a ‘Green Valley’. Here, the world’s largest container vessels have been built. That era is coming to an end as the shipyard is downsizing and closing in the spring of 2012. Thereby changing its name to Lindø Industrial Park, space and facilities are now open for the green offshore industry to rent. The Lindoe Offshore Renewables Center (LORC) was established here in 2009 and contributes to the turnaround.
  12. There is nothing to suggest that nature in the ocean is less worthy or less in need of protection than nature on land but there are today almost no designated areas in the ocean, where nature is allowed to develop without direct human interference.
  13. For offshore turbines, reliability is the keyword according to Anders Eldrup, CEO at DONG Energy. Heading a business with a strategy of covering 85% of energy production with renewables, he predicts tougher demands on both warranties and documented testing of offshore wind turbines.
  14. Wind and wave test centers by LORC Knowledge
    Around the world, test centers are being constructed – some have existed for a long time. Many companies have test facilities of their own. But collaboration and specialist knowledge are also needed from independent test centers. The criteria for inclusion by Oceanwise in this overview of test centers is that the centers must allow industrial access to test facilities, combined with academic input. And of course, the field of research has to relate to offshore renewables. Many test centers have other competences as well, but our descriptions focus on offshore renewables.
  15. Struggling with the waves by Anne Korsgaard
    Waves converted into green energy have the potential to cover the global energy demand. Yet the first commercially competitive device is still to be seen in full scale demonstration.
  16. With feet the size of 100 square meters, the self-propelled jack-up vessel Sea Installer is A2SEA’s bid for the installation vessel of the future. It is designed with the aim of offering the best and least costly installation for offshore wind turbines and foundations.
  17. Despite the persistent and general perception in the offshore wind industry, there is no longer a lack of capacity of offshore turbine installation vessels.
  18. Durability is a weak spot for wind turbines. But some wind turbine designs make it without breakdowns of any kind. Meet a rarity: an 18-year-old turbine with all the original parts.
  19. The world’s first offshore wind farm turns 20 this year. Building it required ingenious solutions in a large number of areas, and many of these solutions are still in use today.
