Energy &
Climate Analytics

The Energy and Climate Analytics department offers expert analysis of atmospheric and oceanographic data to determine site-specific climatic conditions, both wind and marine, as well as the available wind resource at proposed wind farm sites.

Atmospheric & Oceanographic Analysis

Analysis of Atmospheric and Oceanographic data are fundamental inputs to the selection of appropriate turbine classes and layouts for every proposed wind farm, as well as the detailed site-specific design for offshore foundations (Design Basis).

The data and energy experts in this department are also able to use these analysis to estimate the future Energy Production of both onshore and offshore projects.

With a team of world-renowned senior experts in multiple areas, which include:

  • Detailed foundation design
  • Loads calculation
  • Metocean
  • Wind resource and energy yield assessment

WT is capable of providing a unique and integrated site-specific take on offshore wind farm foundation design and turbine selection.

Services

  • Atmospheric and Oceanographic Site Conditions Assessment (AOSCA)

    Onshore & Offshore

    Wind Site Conditions Assessment (wSCA)

    Extreme wind speeds and turbulence can cause loads above turbine design limits. A site meteorological conditions assessment analyses the parameters which will impact turbine lifetime integrity and performance, allowing for an assessment of turbine model suitability to the site and proposed layout, anticipate issues and mitigate risks. Mitigations can range from changing turbine model, layout or implementing a wind sector management strategy. For offshore sites, it is also a key input to loads calculations and foundation design and form a part of the Atmospheric and Oceanographic Site Conditions Assessment, also known as the Design Basis Part A1.

    Offshore

    Marine Site Conditions Assessment (mSCA)

    In this study, a number of parameters affecting foundation loads are estimated. These can be derived from global hindcast models or detailed site specific downscaled mesoscale runs, depending on the level of detail required or maturity of the project. The parameters, such a significant wave height, peak period, currents, tidal range, etc, can be obtained for normal, extreme and/or severe sea states, depending on project specific needs and stage of development.

    Onshore & Offshore

    Other Climatic Conditions Assessment (oCCA)

    WT can assess other meteorological conditions and site-specific risks beyond the wind and marine parameters affecting loads. These will include, for example, risk of lighting strike, solar radiation, probability of earthquakes and tsunamis, and icing on blades.

  • Onshore & Offshore

    Layout design

    Wind farm layouts should be designed in order to maximize the available wind resource and minimize loads on turbines and foundations. WT can design layouts for both onshore and offshore projects that consider the site-specific wind conditions and available resource, terrain inclination, and any other known constraint, whilst also considering the practicality of each individual position and the configuration as a whole. For offshore sites, other relevant aspects such as soil and marine conditions can also be considered. Often an iterative process, the layout design can be undertaken and improved at any stage of the wind farm development

  • Onshore & Offshore

    Measurement campaign specification (MCS)

    A robust and comprehensive on-site measurement campaign, for both wind and marine metrics, is key to reduce uncertainties in the assessment of local resource, and to optimize the design to local conditions. With the combined expertise of WT engineers, the team is able to design wind only, or combined wind and marine measurement campaigns for prospective projects. WT will recommend the most cost-effective strategy for the site, considering all the available technologies such as mast and/or remote sensing devices, whilst still ensuring quality inputs for financial grade Energy Production Assessments. This service is applicable for both onshore and offshore sites.

  • Onshore & Offshore

    Pre-construction Energy Production Assessment (pEPA)

    WT offers independent onshore and offshore pre-construction energy assessment services based on industry best practice, experienced world class experts, and the latest research and tools. With a focus on region specific climatic conditions WT is able to offer financial grade rigorous assessments, of the highest quality, for both onshore and offshore environments.

  • Onshore & Offshore

    Site Procurement and Preliminary Wind Resource Assessment

    Both for onshore and offshore projects, it is often necessary to understand the relative potential of a number of sites/locations. Particularly in new an emerging markets. WT can assist in the initial stages of site procurement, opining on wind resource potential and expected range of site conditions, developing preliminary layouts, hub heights and initial turbine selection, as well as undertaking preliminary Energy Production Assessments.

  • Offshore

    Weather window analysis

    WT wind and metocean experts are able to estimate probabilities of occurrence, of certain atmospheric and oceanographic conditions, affecting activities at sea. These are often called Weather Window Analysis or Weather Downtime Analysis. WT analysts can, therefore, assist developers and vessel operators estimating realistic downtimes associated with different wind speed and wave height operating windows, allowing for a more efficient scheduling of activities and estimation of costs. WT's unique mix of expertise allows for a superior level of accuracy in these assessments, which is rooted in the quality of the input data used and its calibration to specific site climatology.
