Open Sea Operating Experience – Opera

OPERA is a European wave energy project which aims to collect long-term open-sea operating data from offshore and shore installed devices, delivery results for reducing structural costs and greatly increase power production, reduce technology-related uncertainties and advance standards for reducing business risk.


Open-access Journals

The number of open-access journals and publications is growing rapidly. These publications can be viewed and assessed by a wider audience, allowing for a broader and more rapid spread of the research. Open-access publishing operates in the same manner as a traditional journal,  except that the cost of publishing is covered by the author or a funding body. Once a publication is accepted, it becomes available for free online. A lot of offshore renewable energy research is undertaken by small companies with limited budgets, and just like in the case of open-source software, having free resources can have a huge impact.

But wait, there’s more!

UNH-RVAT baseline performance and near-wake measurements

The Reference Vertical Axis Turbine (RVAT) experiments were tidal turbine tests conducted “with a 1 m diameter, 1 m tall three-bladed vertical axis turbine in a towing tank” by Peter Bachant and Martin Wosnik of the Center for Ocean Renewable Energy at the University of New Hampshire. For more info, see their paper.

They have released a repository on GitHub, which contains the processing and plotting code, as well as the derived data set from the UNH-RVAT tow tank measurements performed in Spring 2013:

UNH-RVAT Reynolds number dependence experiment

Researchers, Peter Bachant and Martin Wosnik,  of the Center for Ocean Renewable Energy at the University of New Hampshire  “investigated—experimentally and numerically—the effects of Reynolds number on the performance and near-wake characteristics of a 3-bladed cross-flow turbine” For more info, see their METS paper.

Their are releasing the processing and plotting code, as well as the derived dataset from the UNH-RVAT Reynolds for free on GitHub:


NNMREC Open Data Project

awec Open Data is here! The US Northwest National Marine Renewable Energy Center is hosting data from physical tests for the marine renewable energy research community. Sharing experimental data is a great way to increase the impact of your research and gain wider recognition for your work. Already there are data sets from Autonomous Wave Energy Converter tests in the OH Hinsdale Wave Lab at Oregon State University and from a University of Washington Micropower Tidal Turbine. Bret Bosma, the project’s founder said this: “The motivation for the site is to allow researchers and developers to be able to share their data to foster collaborations and advance the industry.” Great idea Bret!
