Marine Renewable Energy marine-renewal-energy-770x250

Understanding and quantifying the ocean environment is critical to quantifying the risks and opportunities of marine renewable energy projects. Cascadia has the tools, expertise, and decades of experience to help technology and project developers tackle their challenges. Specific services include:

  • Tidal resource characterization
  • Tidal turbine effects on the sea way
  • Wave resource characterization
    • Operational and extreme conditions
  • Wave energy technology development
    • Hydrodynamics
    • Numerical modelling
    • Optimization
    • Physical/experimental modelling
    • Performance assessment

Marine Energy Standards
Cascadia has taken leadership roles in the development of marine energy standards.  We serve on International Electrotechnical Commission Technical Committee 114 as:

  • Convener of the project team maintaining IEC62600-100: Wave Energy Converter Performance Assessment
  • Key subject matter experts on the project team developing IEC62600-102: Wave Energy Converter Performance Assessment at a Second Location
Coastal Hazard Assessmentcoastal-hazard-assesment

Risks to life and property arise from wind, waves and rising water levels.  A coastal hazard assessment seeks to quantify those risks, first by developing an understanding of of the coastal environment as it currently exists, then projecting future changes, and finally calculating the magnitude of low probability, extreme events.  Data feeding into hazard assessments may be measured and/or modelled.

In many cases the hazard of interest is a single physical process such as wind, waves or currents.  In this case, the above methodology may be applied to each physical process individually.  When the hazard is a result of several physical processes, a joint probability approach is used.

Examples of coastal hazard assessment:

  • Wind, wave and current design conditions for fixed-route shipping vessels.
  • Wind, wave and current design conditions for aquaculture rafts and floating structures.
  • Determination of Designated Flood Level and Flood Construction Level for coastal building projects.
  • Determination of Flood Construction Level over broad areas to guide land use planning.
Coastal Modellingcoastal-modeling-770x250

Computational modelling can efficiently provide actionable information about the coastal environment over long periods of time.  Cascadia’s coastal modelling services focus on coastal infrastructure and planning: wind waves, tides, storm-surge and tsunami. Cascadia has experience with a range of models to meet the needs of our clients.

Wind-Waves

  • Phase averaged spectral wave model: SWAN
  • Phase resolved monochromatic/spectral wave model: REF/DIF-1REF/DIF-S
  • Fully non-linear hydrodynamic wave model: SWASH
  • Tides, Storm-surge and Tsunami
  • General purpose hydrodynamic model: RiCOM

Tsunami Modelling
Cascadia collaborates with industry experts in geology and geophysics to provide deterministic and probabilistic assessment of tsunami hazards.  Using the RiCOM software, specific hazard metrics such as maximum inundation height, inundation time and maximum current speed can be calculated for each fault or landslide scenario.  A collection of scenarios, along with their historical frequency can be used to generate a probabilistic estimate of the tsunami hazard.

Model Development
Cascadia is active in developing and coupling numerical models.  For example we have engaged in collaborative projects to couple detailed tidal turbine models within tidal resource models and detailed wave energy converter models within wave resource models.

Model Grid Development
Cascadia participates in the development of a number of grid generation tools including TQGG.  Our staff have a wealth of experience in creating high quality unstructured computational grids from variety of disparate data sources.

Featured Projects

Cascadia Coast Research, in collaboration with the University of Victoria and Aalborg University, Denmark, are making their cutting edge methods for actively controlled physical model wave energy converter power take-offs (PTOs) publicly available. Detailed descriptions and validation of the methods as well as real-time control codes for two separate WECs (1:25, 1:20 scale) will all […]
Cascadia Coast Research led a project, in partnership with University of Victoria and University of Edinburgh, that produced a publicly available, wave power production data set aimed to address global knowledge gaps in wave energy production uncertainties. The project involved: compiling and preparing 10 years of wave resource data at 3 hr intervals for 4 […]
Cascadia Coast Research, in partnership with University of Victoria’s West Coast Wave Initiative, implemented suite of models that have produced the most comprehensive and accurate wave analysis off the coast of BC, Canada to date. Over the 4 year project, the models and results helped the West Coast Wave Initiative achieve their goal to create […]
