Offshore wind

Sustaining the growth of one of the world’s leading renewable energy technologies

Climate change is the most serious environmental challenge we face today — a challenge with a direct impact on social, economic and ecological issues. It has become necessary to take appropriate measures to cope with the impacts of climate change. At the same time, it has become increasingly vital to tackle the problem at the source – by reducing anthropogenic carbon emissions. In this context, ‘green’ technologies (providing carbon-free energy) are attracting increased interest from industries and governments.
Wind power has emerged as a leading renewable technology. With respect to other sources of energy, it is being developed the fastest globally. Today, wind turbines satisfy nearly 2% of the world’s electricity demands. Currently, there are some 160 offshore farms within European waters either in operation, under construction or being planned. This rapid proliferation in Europe portends a global trend and, to ensure the sustainability of these developments, several challenges are to be overcome. These include coping with harsh environmental conditions when moving further offshore, preserving the fragile ambient ecosystem and ensuring maximum efficiency — at sustainable costs.

THE CHALLENGES

  • Optimising farm development — from site selection to construction
  • Coping with harsh environmental conditions
      • Ensuring sustainability of structures
      • Minimising environmental impact
  • Ensuring efficient and effective operations

OUR APPROACH

Offshore wind farms are exposed to a harsh environment. Based on a thorough understanding of hydraulic and Metocean conditions, we help you make informed decisions on structural design and project feasibility. This understanding also enables us to determine the implications of the developments on the ambient environment and ensure that these are limited. We work in close collaboration with developers, consultants, contractors and authorities to unlock the right solution.

OUR SOLUTIONS

We've developed scientific standards and tools to support and optimise the design of wind farms as well as ensure the safe construction, operation and maintenance of wind farms. Our innovative solutions are based on a combination of field data collection, on-line monitoring as well as numerical and physical modelling. We also have the knowledge and tools to help you assess and mitigate the impacts of your developments on the surrounding environment. Our solutions include ecological sampling, habitat modelling, noise impact analysis, barrier and collision studies and seabed and coastal impact assessments.
