Offshore wind technical services


To provide independent technical consulting, software, certification, testing and inspection services to the offshore wind energy industry.

The development of offshore wind farms presents its own unique set of challenges. The limited access to on-site wind resource measurements at the hub makes it more difficult to fully characterize the wind resource in offshore environments.

Meeting this challenge requires a variety of creative solutions.

From the assessment of wind resources and energy to oceanographic studies, including the development and design of wind farms, the success of your project is our priority. UL’s offshore team specializes in the management and integration of multidisciplinary aspects of offshore wind development and has designed and evaluated over 200,000 megawatts of wind and solar projects, both on land and at sea.

Technical advice

In the areas of offshore and coastal development, our technical advisory group designs and implements offshore wind resource assessments and ocean studies, including the design and review of meteorological towers.

UL uses innovative measurement approaches using buoys, fixed and floating platforms, and remote sensing technologies for wind measurement and atmospheric characterization. We are also a leader in offshore studies that pave the way for the development of a viable offshore industry in the United States, including cost-benefit analyzes, industry data needs assessments and news assessment. technologies.

Certification and testing

We help evaluate offshore wind turbines and their components. Some of the testing services offered include mechanical load testing, validation and type testing, energy performance testing. We are also involved in offshore wind research.

Some of the topics we have worked on include incoming wind and turbine wake, water pressure rings, wave loads, acoustics and operating noise, all of which have an impact on the performance of the turbine. ‘an offshore turbine.

Eight offshore wind services

Support for project development

Decisions made during the early stages of an offshore wind project’s development are critical to long-term success. We help you navigate the complexities and mitigate the risks associated with site screening, feasibility, resource assessment, plant design, energy assessment, selection and suitability of technology, infrastructure, plant balance, permitting and environmental assessment.

Asset Management

Growing investments in renewable power plants, aging fleets, and the desire to provide security while maximizing asset value are driving businesses to our asset management services. We help you assess and optimize your project operations and maintenance, contracts, health and safety, and remaining useful life.

Our goal is to help you maximize power generation, reduce downtime and O&M costs (O&M costs), ensure project safety and take in charge of the key decisions concerning the lifespan of the assets and the renewal of the capacity. See AWSDEWI Asset Management for more information.

Due diligence

We provide comprehensive, flexible and timely due diligence services for the wind industry. We help make the critical financial close of a wind project as smooth and successful as possible.

Our technical and commercial expertise, as well as our understanding of the intricacies of project finance, make us the ideal partner for developers looking to raise capital. Our team of engineers and technical advisors will help you prepare your project for financing, mitigate risk, and ensure it is technically sound and ready for construction.

The approach we use for our Independent Engineering (IE) reporting has been carefully reviewed with some of the world’s leading arrangers and lenders, so we know exactly what they are looking for, which helps ensure a timely transaction. . Visit AWSDEWI Due Diligence for more information.

Network solutions

Our network solutions services focus on integrating large amounts of renewable energy into the power grid. As the renewable energy market grows, it is also important to quantify the impact of centralized and distributed wind and solar technologies on our power infrastructure.

Understanding the characteristics of power generation that result from the variability of wind in space and time is essential to ensure safe, reliable and economical operations. See AWSDEWI Grid Solutions to learn more.

Software and data

We offer a range of software products to support the development, evaluation and operation of renewable energy projects. These products leverage our knowledge and expertise to empower your team to do their jobs more productively and efficiently and the ability to work more independently. See AWSDEWI Wind Software for more information.

Large-scale grid, market research and research

Developing good policies and effective plans to develop renewable energy requires reliable and detailed information on resources, energy production potential, production characteristics of facilities, economic impact and other factors.

If you’re tasked with putting in place the policies or infrastructure to ensure a healthy growth trajectory and reliable energy delivery, we can provide you with the data and expert advice you need. Visit AWSDEWI Research and Advance Studies for more information.


As wind energy technologies advance, their safety, reliability and continued performance must be ensured. As security science experts, we help our clients manage these risks through product, project and network code compliance certification.

UL certification extends compliance and provides assurance and confidence in the reliability of renewable energy technology. See AWSDEWI Certification for more information.

Tests and inspections

Manufacturers seeking to verify the safety, reliability and performance of renewable technologies, such as wind turbines and peripheral equipment, rely on our technical and scientific safety experts to help them manage risk. We operate renewable energy test sites around the world and perform field inspections of operating equipment. Visit AWSDEWI Testing and Inspection for more information.
