As the world continues to seek a cleaner and more sustainable energy source, offshore wind has proven to be a viable alternative to electricity generated by traditional fossil fuels. Offshore wind farms offer a significant opportunity to produce large amounts of electricity with minimal environmental impact. However, the installation and maintenance of offshore wind turbines require specialized equipment and expertise. In this article, I will discuss how motion-compensated gangways are revolutionizing offshore wind in the US, and their role in creating jobs and green energy.

Introduction to offshore wind power

Offshore wind turbines are installed in the ocean, either bottom-fixed or floating, and are used to generate electricity. The turbines harness the energy of the wind to turn their blades, which then drive a generator to produce electricity. Offshore wind turbines have several advantages over onshore turbines. They can produce more electricity due to the stronger and more consistent winds offshore. Additionally, offshore wind turbines have less visual impact on land, and their noise pollution is minimal.

Benefits of motion-compensated gangways

One of the challenges of offshore wind power is the installation and maintenance of the turbines. The turbines are often located in harsh marine environments, which can make it difficult to access them safely. This is where motion-compensated gangways come in.

Motion-compensated gangways are specialized walkways that connect a vessel to a turbine. These gangways are designed to compensate for the motion of the vessel caused by waves, which ensures a safe and stable connection to the turbine. Using motion-compensated gangways for turbine installation and maintenance reduces the risk of accidents and enables work to continue in a wider range of weather conditions.

The current state of offshore wind in the US

The US has been slow to adopt offshore wind power compared to other countries. However, this is starting to change. The first offshore wind farm in the US, the Block Island Wind Farm, was completed in 2016 off the coast of Rhode Island. Since then, several other offshore wind projects have been proposed and are currently in development.

Offshore wind is still a small fraction of the total wind power capacity in the US, which is over 100,000 megawatts. However, the potential for offshore wind power in the US is significant. The Department of Energy estimates that the US has over 2,000 gigawatts of potential offshore wind capacity, which is over six times the current electricity generation capacity in the US.

Innovations in motion-compensated gangways technology

As the offshore wind industry in the US grows, so does the need for specialized equipment and technology. One area of innovation is motion-compensated gangways. As the industry has matured, the technology used in motion-compensated gangways has continued to evolve, leading to more advanced and reliable systems.

One example of this is the Ulmatec 32m gangway. This system uses active motion compensation to stabilize the gangway, allowing for safe and efficient access to the turbine. The gangway can operate in significant wave heights of up to 4.5 meters, allowing for work to continue even in challenging weather conditions. Additionally, the gangway can be fitted with a crane function to lift up to 3 metric tons fully motion compensated offshore or 6 metric tons during harbor loading and offloading.

Ulmatec has developed and manufactured novel and complex motion compensated systems for decades, with a large portion of these systems in operation in the US. Our US subsidiary is the base for support, parts and training on our complex systems. These systems also require a thorough yearly check and verification to retain class certification, this will also be arranged through our local base.

Future prospects of offshore wind power in the US

The future of offshore wind power in the US is promising. The Biden administration has set a goal of 30 gigawatts of offshore wind power by 2030. This goal is ambitious but achievable, given the significant potential for offshore wind in the US.

The growth of offshore wind power in the US will have several benefits. First, it will create jobs. The offshore wind industry requires specialized skills and expertise, and the development of offshore wind farms will create thousands of jobs in areas such as engineering, construction, and maintenance.

Second, offshore wind power will help reduce greenhouse gas emissions. The electricity generated by offshore wind turbines is clean and renewable, which reduces the reliance on fossil fuels. This, in turn, helps to reduce the carbon footprint of the US and mitigate the effects of climate change.


In conclusion, motion-compensated gangways are revolutionizing the offshore wind industry in the US. These specialized systems enable safe and efficient access to offshore wind turbines, making it easier to install and maintain them. The growth of offshore wind power in the US has the potential to create thousands of jobs and reduce greenhouse gas emissions. As the technology used in motion-compensated gangways continues to evolve, the offshore wind industry will become even more efficient and reliable, making it an increasingly important source of green energy in the US.
