Gemini: one of the world’s largest offshore wind projects

  • 85 kilometres north off the coast of Groningen
  • 150 4 megawatt Siemens wind turbines
  • 600 megawatt of renewable generating capacity
  • 785,000 households will be supplied with renewable electricity

Van Oord realised one of the largest offshore wind projects in the world: the Gemini Offshore Wind Park. How? With great teamwork, a lot of knowledge, and the highest-quality equipment. This challenging project consisted of the installation of 150 4 megawatt Siemens wind turbines, which will supply a total of 600 megawatt of renewable energy to 785,000 households by 2017. With a value of more than EUR 1.3 billion, it’s one of the largest EPC contracts in Van Oord’s history. 

Huge step towards a sustainable future

Being sustainable is an important issue for Van Oord. That’s why this project means so much to the company. The Gemini offshore wind project represents an important step towards achieving the targets set out in the Dutch Energy Transition Agreement. In this agreement, the Dutch government, several organisations, and the private sector committed themselves to increase the share of renewable energy from 4% in 2014 to 16% in 2023. Thanks to the 600 megawatt generated by the Gemini offshore wind project, the Netherlands will be one step closer to reaching this goal. Van Oord’s role is not only as a contractor, but also as shareholder with a 10% equity stake in this project. The other shareholders are Northland Power Inc. (60%), Siemens Project Ventures (20%), and HVC (10%). Jointly, we are making an important contribution to the growth of sustainable energy in Europe.

Due to the growing world population, the demand for energy is rising constantly. As an EPC contractor, we believe in the future of renewable energy. That’s why we continuously invest in innovative solutions that contribute significantly to making sustainable energy more competitive. Van Oord and its Marine ingenuity are already meeting this challenge head-on. The Gemini offshore wind project demonstrates our progressiveness.

FaunaGuard: innovative sound system

Van Oord distinguishes itself thanks to its ingenious people, who are always looking for smart techniques and solutions: we call it Marine ingenuity. The FaunaGuard system, an innovative method to protect marine fauna, was developed by Van Oord and SEAMARCO (Sea Mammal Research Company). FaunaGuard is an innovative system for using safe levels of underwater acoustics to drive marine mammals and fish temporarily away from active construction zones.

To make this comprehensive and complex project a success, we have put together a multidisciplinary team that includes members with various specialities and nationalities. Our team, both on the ship and on shore, consisted of more than 400 motivated and hardworking people, all of whom helped to deal with the numerous challenges presented by this complex project. We can be proud of what we bought together in close cooperation with the client.

Exceptional offshore equipment

Van Oord was the EPC contractor for the Gemini Offshore Wind Park and was responsible for Engineering, Procurement and Construction. The enormous size of the project reflected in the number of suppliers and the scope of the contract: it’s one of the largest contracts in Van Oord’s history. Working on such a prestigious project demands the best equipment and people. Two of Van Oord’s vessels, Nexus and Aeolus, were deployed on this project to show their outstanding abilities. Offshore installation vessel Aeolus installed, working together with partner vessel Pacific Osprey, all of the 150 monopiles in a record time of 3.5 months: one month earlier than scheduled, after that the installation of the windturbines could start. The cable-laying vessel Nexus started on the project in the summer of 2015, its first job after being launched. Together with multi-purpose vessel Jan Steen and cable-laying vessel HAM 602, Van Oord deployed a strong complement of exceptional offshore equipment.
