A conditional agreement for turbine supply between Parkwind and MHI Vestas was announced at the Wind Europe conference in Copenhagen today (26 November 2019). The agreement covers the supply of turbines for Parkwind's Arcadis Ost 1 offshore wind farm project.

The announcement follows news that the Arcadis Ost 1 project will be the first offshore wind farm that will make use of a floating vessel for the installation of Wind Turbine Generators. This is the result of a year-long joint development between Parkwind, Heerema Marine Contractors and MHI Vestas Offshore Wind.

Parkwind was named winner of the 257 MW Arcadis Ost 1 offshore wind farm in the German offshore wind auction back in 2018. The project, located 20 km northeast of the island of Rugen in the Baltic Sea, will consist of 27 MHI Vestas V174-9.5MW turbines mounted on monopile foundations and one offshore substation. It is estimated to meet the energy demands of 300,000 German households.

The challenging soil conditions at the Arcadis Ost 1 site saw Parkwind look at possible alternatives to traditional installation methodologies. In joint cooperation with Heerema Marine Contractors and MHI Vestas, a floating installation method was developed. According to the three companies, the method avoids all interaction with soil, thereby reducing the project’s risk compared to a traditional jack up installation method. This is said to enable a reduced installation time.

The developed method is based on using a floating installation vessel to assemble the wind turbine components. The vessel will have all turbine components on its deck including a dummy tower. This tower will provide a stable platform on-board the vessel, to assemble the nacelle and the blades. The first step will be lifting the tower onto the pre-installed turbine foundation. The second step includes lifting the nacelle onto the dummy tower and attaching the blades.

The three companies stated that this process ensures full control over the blades, thereby guaranteeing a safe and highly reliable blade assembly. After the Rotor Nacelle Assembly on the installation vessel, the complete nacelle will be lifted as one piece onto the tower.

“Taking the turbine installation based on a floating vessel from theory to practice is a major step forward for the offshore wind industry,” commented Parkwind’s co-CEO Eric Antoons, “supported by Heerema Marine Contractors and MHI Vestas, we saw this as the best solution for our German Arcadis Ost 1 project where soil conditions are challenging.”

Koos-Jan van Brouwershaven, CEO of Heerema Marine Contractors, added: “More than one year ago, Heerema Marine Contractors, together with our partners MHI Vestas and Parkwind, started an intensive research to find out the possibilities of installing turbines utilizing our fleet of floating assets. In our Simulation Center, we created an authentic visualization of the local situation, including crane and vessel controls, realistic weather conditions, sea swell patterns and sea bed conditions. This collaboration led to an innovative method which will be used for the installation of turbines in the Arcadis Ost 1 wind park. Heerema Marine Contractors is very proud to participate in this unique project. It shows our ambition to remain a frontrunner in the offshore energy market, and our commitment to operate in wind projects all over the world.”

“We are exceptionally pleased to be chosen by Parkwind once again for such a milestone project,” said Henrik Jensen, MHI Vestas Chief Sales Officer. “Today’s announcement is a testament to the strong partnership and trust between Parkwind and MHI Vestas as we embark on our fifth project together. We look forward to bringing our technology and experience to bear at Arcadis Ost 1 and contributing to the German renewable energy transition.”
