Offshore wind case studies

With over 10 years in the renewable energy industry, SgurrEnergy has developed a wealth of experience and expertise in offshore wind, working on a number of high-profile offshore projects, supporting developers and owners as well as lenders and investors.

The dedicated team look after projects from initial concept and planning, through to the management of the construction phase and post-construction power performance testing and optimisation.

The complexity of offshore wind projects varies, as does the site environment and the project’s needs. Because of our track record, we are well equipped to deal with these complexities- whether it be enhanced health and safety management or harsh construction conditions.

Below is a snapshot of some of the work that SgurrEnergy has undertaken in offshore wind, taking you through some of our key global projects.

To read what our clients have to say about us, take a look at our client testimonials and you can find out more about the full spectrum of offshore wind services that we offer in our services section.

Meerwind offshore
Client: KfW IPEX-Bank GmbH
Location: North Sea (Germany)
Capacity: 288MW
Service: Lenders’ engineer

German project and export finance bank KfW IPEX-Bank GmbH acted as technical bank for the lenders on this 288MW offshore wind farm.  We were commissioned as lenders’ engineer to the club of origination banks and provided technical due diligence for their investment in this, Germany’s second project-financed offshore wind farm.

In advance of our full lenders engineer services, we provided independent technical and commercial advice to both the project company and its financial advisors on the bankability and technology risks of the project, enabling a faster and smoother project finance process.

SgurrEnergy provided a wide range of services to the lenders including:

  • Appraisal of the technical design, engineering and construction contracts
  • In-depth reviews of technology, construction and operational risks
  • Review of wind turbine and balance of plant equipment suppliers
  • Review of key financial model inputs, including construction schedule and costs, contingency levels and schedule float, long term operating costs and contingencies, energy production and availability targets
  •  Energy yield assessment
Moray Firth offshore wind farm zone (Round 3)
Client: Moray Offshore Renewables
Location: UK
Capacity:
Service: Health and safety, environmental requirements and risk assessment

Our client engaged us to provide advice on the health and safety and environmental requirements of the UK offshore market to assist with their development of ‘next generation’ wind turbines.

We conducted detailed studies of current and emerging regulations, standards and best practices regarding machinery safety, offshore operations, aviation and navigational risks, and environmental impact across the full lifecycle of an offshore wind development.

Detailed study findings were presented in guidebook format, supported by training workshops and highlighted areas where wind turbine designers have direct responsibilities and how their designs can assist other duty holders in fulfilling their responsibilities.

Further work has since been conducted on behalf of this client including hazard identification and risk assessment of lifecycle technology, safety and environmental issues affecting the design, installation and operation of wind turbines on offshore projects.
