Thoroughness and pioneering for more than 50 years

We at ISC have always taken pride in doing things properly and thoroughly. Simultaniously we are pushing the boundaries of engineering. One does not exclude the other. Within renewable energy, it is crucial that you dare to and can innovate – the industry has wind in its sails but we have to insist on pushing further. ISC is leading the way and insists on challenging and moving the notions of what is possible.

Power-to-x and offshore hydrogen are seriously on the way forward, and we are at the forefront – read about our project with Strandmøllen A/S on hydrogen production and storage. The same applies to developments in floating wind. We do this based on decades of experience with offshore wind energy both within substations and foundations. ISC has been a leader in offshore substations for two decades with a market share of more than 60% of all substations on 3 continents, the world’s largest offshore substation and the world’s first offshore substation built in our backyard in the Baltic Sea in 2003.

It is therefore given that we at ISC are involved in the development of both offshore hydrogen and floating wind.

Offshore pioneers – the world’s first offshore substation in 2003

We developed and designed the world’s first substation for an offshore wind farm in 2003: Nysted Offshore Wind Farm in the Baltic Sea.

That marked the beginning of almost 20 years with ISC as leading consultants on offshore projects in the field of renewable energy. Projects that have contributed to pushing the boundaries of what one manages today when it comes to utilizing the enormous amount of renewable energy that is found in offshore winds. We believe that we can make even better use of offshore winds so that we can accelerate the sustainable conversion of our energy consumption and reduce our common climate footprint.

Since the construction of Nysted Offshore Wind Farm, ISC has been a pioneer in the development and innovation of solutions in renewable energy. This has made us the market leader in offshore wind substations. We are committed to finding the solutions for the future, and for better utilization of renewable energy sources – including power-to-x and offshore hydrogen.

Our fingerprint on more than 60% of the market – including the world’s largest offshore substation

Our engineers’ unique competencies and expertise in the design of the main elements in offshore wind farms, make us a preferred consultant in offshore wind energy worldwide. This has resulted in us taking a leading role in the market with a market share in the design of more than 60% of all manufactured offshore substations. For example, we have prepared detailed designs of the offshore substation and RCS for the world’s largest offshore offshore wind farm – Hornsea ll which generates 1320 MW.

43 offshore substations in Europe, Asia & USA

We have provided innovative consulting to clients in Europe, Asia and the United States on the design of more than 43 offshore substations as well as a host of projects related to offshore wind turbine foundations. As an industry leader, we have solid experience and an impressive catalog of successfully executed projects – and we are ready to help our clients on their future offshore growth journeys. We consult on complete detailed design of both offshore substation and wind turbine foundations. In collaboration with our clients and partners, we always strive to find the best and most effective solution that balances CAPEX and OPEX for our clients.

As market leaders with more than 60% of substations worldwide, including the world’s first and the world’s largest (HVAC) substations, we are the obvious choice for your next offshore energy project.

Our engineers have unique specialist knowledge in offshore substations’ design, development, and execution. This knowledge is based on the designs of 43 successful and well-executed substations located on large sea areas globally, as seen above. This means that our engineers have solid experience collaborating with clients from all over the world. The best results are created by a collaboration between clients, partners, and our multidisciplinary team of engineers.

We consult within all phases of the project

We provide independent consultancy, both directly to owners of wind farms and developers as well as to EPCI contractors.

Our key competence in the design of substations lies in our ability to carry out all necessary tasks associated with a substation design. This covers all phases from FEED/concept design through detailed design, documents for tender, assistance during manufacturing, installation, and commissioning as well as following phases such as supervision and follow-up.

Energy optimization from water to land

Offshore substations play an essential role for larger offshore wind farms. The essence of an offshore substation lies in the ability to collect and maximize the energy produced in the wind turbines. Thereby, large amounts of potential energy losses can be significantly reduced, resulting in larger amounts of electricity being exported to land.

More than 30 projects with offshore wind turbine foundations

References for WTG foundations

We offer consulting in the design of foundations for wind turbines. Our expertise in the field comes from more than 20 years of experience in the design of offshore structures. In addition, we have been involved in the design of wind turbine foundations on more than 30 projects (see below). 

We have experience leading as responsible for design or as external consultants for Ørsted among others.

We have experience working with local authorities throughout Europe to create regulatory approved solutions in accordance with local regulations.

Monopile and Jacket foundations

Our offshore experience has given us expertise that we utilize in WTG foundation projects. This covers various types of underwater structures, including the monopile and jacket types. We work at several sea depths and can design both primary and secondary steel.
