WEC-Sim (Wave Energy Converter SIMulator) Code Development and Training Class

Sandia National Laboratories and the National Renewable Energy Laboratory (NREL) jointly have been developing WEC-Sim, an open-source time-domain numerical model for simulating wave energy devices that are comprised of rigid bodies, power-take-off systems, and mooring systems. The WEC-Sim development team has continued to improve the code’s capabilities and recently held a workshop/training class with the [...]

University of Illinois uses Sandia Labs’ reference hydrokinetic turbine to study potential bed erosion effects

Sandia Labs Water Power Technologies Department promotes open-source marine hydrokinetic research by disseminating information on MHK technology designs initially developed as reference models to benchmark performance and costs. Sandia developed a scale model of a reference hydrokinetic turbine to minimize power performance losses from soiling/bio­fouling and reduce the likelihood of cavitation. Researchers at the University of Illinois Ven Te Chow Hydrosystems Laboratory recently tested the model to evaluate [...]

Open-source extreme conditions modeling tools

The extreme conditions modeling project (ECM) will be releasing two numerical tools for use in modeling extreme conditions of wave energy converters (WECs). Sandia and the National Renewable Energy Laboratory have developed the WEC Design Response Toolbox, a collection of algorithms that address components of the design response analysis process. The available methods fall into five categories: [...]

Sandia releases 2nd edition of the U.S. WEC test site catalogue

Sandia has released the second edition of the Wave Energy Converter Test Site Catalogue characterizing wave energy resources to facilitate device deployments and testing. The catalogue presents metocean data at eight U.S. wave energy converter (WEC) test sites. The catalogue will enable WEC developers to compare wave resource characteristics between sites and select the best test [...]

Experimental testing of wave energy converter (WEC) controls

U.S. Navy's Maneuvering and Seakeeping Basin (MASK) Sandia has begun experimental testing on wave energy converter (WEC) modeling and controls. The test program focuses on model validation and system identification to produce high-quality data for control design of WECs. In partnership with the Navy, Sandia is conducting the tests at the maneuvering and sea-keeping (MASK) basin [...]

Paper and Presentation at OCEANS2015

Carlos Michelen and Ryan Coe recently published results from research comparing various methods for producing short-term (i.e. sea-state specific) extreme response distributions. These methods are needed to statistically quantify the extreme response (e.g., tension in the mooring line of a wave energy converter) based on modeling results. (Note that these results might be obtained using [...]
