Investigating the Value of Simulated Wind Data for Wave Resource Characterization at US Test Sites

Sandia is cataloging wind, surface current, and wave data at US test sites to provide detailed and consistent wave-resource data that wave-energy developers can use to evaluate and compare different test sites. As part of this effort, Sandia compared National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) simulations for wind speed and […]

Quantifying Offshore Wind Scour with Sandia’s Environmental Fluid Dynamics Code (SNL-­‐EFDC)

A key risk driver in offshore wind projects is the potentially detrimental interaction between offshore wind substructures/cables and the seafloor. In previous years, Sandia developed methods for evaluating regional sediment stability with the use of combined wave, circulation, and sediment dynamics modeling. Knowledge of sediment stability—not only in the vicinity of an offshore wind deployment, […]

Sandia Funded to Model Power Pods for Utility-Scale Wave-Energy Converter

Planning an open-water test facility for utility-scale wave-energy converters (WECs) within the US requires a multifaceted approach. Concerns regarding the siting and permitting, the environmental interactions, the device performance, and the cost of the facility must all be simultaneously addressed. The DOE has started to investigate a utility-scale WEC testing facility with the recent awards […]

Wave Energy Resource Characterization at US Test Sites

Sandia is creating on an open-source catalog for wave-energy converter (WEC) developers with a detailed and consistent wave resource characterization at three US test sites the Wave Energy Test Site (WETS) in Kaneohe Bay, HI; the North Energy Test Site (NETS) offshore of Newport, OR; and a potential site offshore of Humboldt Bay, CA. Hindcast […]

Sandia Completes Hydrostructural Analysis of Ocean Renewable Power Company’s TidGen® Turbine

Sandia performed an independent hydrostructural analysis of the Ocean Renewable Power Company (ORPC) TidGen® turbine, with a focus on the bolted-joint connections. Sandia’s CACTUS hydrodynamics software was used to predict dynamic loads on the turbine, and these loads served as input to structural dynamics analysis, performed using Abaqus finite-element analysis (FEA) software. The analysis examined […]
