Sustainable use of clean energy offshore

Identify new offshore wind farm opportunities and evaluate their potential environmental impact with high-quality data, cutting-edge technology and in-depth analyses.

Where are we now

To achieve the global goal of producing more clean energy, the offshore wind market has grown at rapid pace – nearly 30% per year since 2010. In addition, the cost of this form of renewable energy has fallen in recent years, further propelling the uptick. To continue at this pace, it’s imperative to more efficiently evaluate wind, wave and current conditions and the potential impact of your next clean offshore energy project on the environment.

The challenges

In-depth knowledge and understanding of site-specific conditions are vital to properly design an offshore wind farm being it fixed or floating. In particular, environmental loads and response analyses are critical to ensure a proposed wind farm can safely withstand the conditions at a given site. It is equally important to determine the impacts a wind farm may have on life underwater to guarantee a sustainable generation of clean energy. 

How DHI can help

Since 1991, DHI has developed standards and tools to optimise wind farm design and ensure safe construction, operation and maintenance. In fact, more than 85% of commissioned offshore wind farms include DHI input. Recognised as best-in-class by certifiers, our methods, data and ecological modelling tools allow you to identify potential impacts early and throughout the project cycle to ease approval processes and reduce scheduling and investment risks to make your project more bankable.

Rely on certifiable environmental design criteria to support all offshore wind elements

To establish safe, solid and cost-effective environmental design criteria, one must rely on proven technology, accurate data and strong metocean engineering expertise. Offshore wind infrastructures are often subject to harsh environmental conditions which complicates the matter requiring close collaboration with certification bodies and developers. DHI has earned the reputation of being at the forefront of the industry. Count on us to secure a quick and smooth process and help you build faster, smarter and at a lower cost.

Secure environmental clearance with input from specialist modelling and monitoring

The risk of seabird collisions and the impact of underwater noise on marine mammals are the top environmental issues offshore wind farms face today. To mitigate these risks, MUSE, DHI's innovative, multi-sensor bird detection system, offers 24/7 monitoring to greatly reduce downtime. Couple MUSE with recognised ecological modelling that integrates hydrodynamics, habitats and animal movements for the most precise impact assessments that fully comply with environmental regulations.

Protect your assets with seabed mobility and scour risk predictions and assessments

High sediment mobility rates from ocean currents, tide, waves and hyperpycnal flows can change the sediment profile rapidly. To assess this risk and mitigate its impact, DHI provides robust predictions of the likely range of future seabed levels at wind turbine locations and cable routes using historical surveys, satellite data and geotechnical and geology data in combination with sediment transport models. In addition, we can predict the risk of long-term scouring around any type of wind turbine foundation and offer cost-efficient mitigation options and conceptual design using our Scour Calculator, CFD or physical modelling.

Rely on accurate load and response analyses of fixed and floating wind support structures

As mentioned, offshore wind farms are often exposed to harsh ocean environments. Therefore, it’s critically important to carefully evaluate hydrodynamic loads on fixed and floating foundation structures. To support decision making on structural design and project feasibility, DHI provides key insight on metocean conditions and relevant loads through the use of physical modelling and CFD. Our depth of knowledge and access to best-in-class resources has led to the development of innovative solutions in foundation structures that can be put to work for you.

Floating wind farms: A new dimension to offshore wind energy

Over the past decades, different methods and solutions have been deployed to crack energy supply challenges – especially renewable energy sources such as wind and solar power. Even though wind has proven to be an important source of energy, there are still more wind power opportunities waiting to be deployed such as floating offshore wind farms. Floating wind turbines expand the feasible area for offshore wind energy development, reduce visibility from shores and can be placed in areas with more consistent and stronger wind speed.
