Site appraisal and concept design (1)

Site Appraisal and Concept Design

Our consultancy, Geo-data and site modelling helps you optimise and derisk your offshore wind farm site appraisal and concept design. Using our integrated solution, we provide the geophysical, geotechnical, metocean and environmental information required for site selection, concept design and modelling, allowing you to make informed decisions and analyse the residual risks.

Site impact and legislative evaluation

Assessing the visual, audible and environmental impact of the proposed wind farm is essential in the permitting process and confirms assurance and support from local stakeholders. The legislative process and associated approvals related to key site considerations is also required, such as, existing local infrastructure, existing rights of servitude and access, pre-existing license agreements, navigational routes, etc. To ensure timely completion of the initial offshore wind farm development phase with a constantly evolving concept design, a broad site impact and legislative evaluation scope is key. Our comprehensive consultancy services are adaptable to the evolving concept design to meet your project requirements.

Coastal process assessment

The impact of erosion and sedimentation progressively caused by natural processes and by the addition of an offshore wind farm is critical in the site appraisal and concept design phase. This will affect the reliability of the built wind farm and potential changes to the coastline over time. Our extensive Geo-data and supporting services enable us to assess and advise on the impact your offshore wind farm development may have on the coastline.

Site investigation surveys

  • Environmental measurement and insights - required throughout the offshore wind farm life cycle, especially within the site assessment and permitting process, as it can affect the location and assurance of project milestones.
  • Measuring and modelling metocean factors - Using metocean buoys we measure wind resource to ensure generation capacity is maximised through the site location and concept design, and for improved levelised cost and revenue of energy for your project.
  • Early insights into seabed geomorphology, bathymetry and geology - through desktop studies, geophysical and geotechnical surveys, and utilising our industry-leading 2D and 3D seismic solutions, ensure a lower build cost and derisks the foundation, inter-array and export cable route design.

 

There are two key phases during the early development of any offshore wind farm, which the site appraisal and concept design solutions apply.

Site appraisal for resource assessment, site refinement and permitting

Wind resource mapping

Understanding wind resource is key towards the economic model for the offshore wind farm development. Acquiring high resolution wind resource data across the site can impact the decision of a wind farm being bid or not.

Morphological studies

Morphological studies and the movement of the seabed is a critical design parameter to assess current and future potential scour impact, risk of infrastructure de-burial and possible failure to the offshore wind farm.

Management of marine species and habitat

Monitoring and management of marine mammals and other species throughout the design and installation phases is essential to an environmentally conscious development. It is important to assess the impact and develop a strategy during the site appraisal stage to mitigate potential risks to protect the surrounding environment.

Permitting

Several stages of an offshore wind farm development require stakeholder management, agreement and permitting before the development can proceed. Input to this process includes above parameters and are key to successful commencement of the development.

Concept Design

Ground model and consultancy

The development of a ground model is key to understand the site parameters and the development of the array concept. A detailed understanding of the available and acquired data through access to expert advice can be the economical difference between a profitable concept design and one that is not bid at all.

Geophysical characterisation

Conducting geophysical surveys at offshore wind farm sites, turbine locations and planned routes for the power cable is essential to understand the geomorphology and sub-surface characteristics and is used to further refine the ground model.

Geotechnical characterisation

In situ geotechnical testing, sampling and coring combined with geotechnical sample and core tests conducted within our in-house laboratories helps to characterise ground conditions at your offshore wind farm site and inform the ground model.

Boulder detection

An understanding of locations and size of boulders is important, as it can impact the concept design and installation phases requiring contingencies to be accommodated. This includes, the turbine locations, engineering design specifications, and potential engineering risks.

  • High-quality and fast concept development - Early access to accurate Geo-data insights refined through the concept development reduces the need for extensive site appraisal by focussing the concept design on more defined locations.
  • Tailored Geo-data and consultancy services - A range of solutions combined with geoconsultancy services tailored to address the key challenges and project requirements encountered during the initial site appraisal and concept design phases.
  • Adaptable to evolving design requirements - Continuous access to Geo-data and advice on actionable insights including, application to the concept design tailored your evolving design requirements.
  • Globally consistent data quality standards - Consistent and high-quality solutions delivered globally with local expert knowledge and advise available for the variances across regions and locations wherever your project may be.
