Vestas to test sustainable aviation fuel

Vestas will test Sustainable Aviation Fuel (SAF) at the Baltic Eagle Wind Farm in the Baltic Sea during 2024. The pilot project entails Vestas technicians and jack-up vessel crew using helicopters partly powered by SAF to transport themselves to and from the Baltic Eagle wind farm during the construction phase of 50 offshore wind turbines.

SAF is a fuel produced from bio-waste materials such as used cooking oil or tallow. Because SAF can help reduce lifecycle greenhouse gas emissions associated with air travel, it is generally considered a more sustainable alternative to conventional jet fuel. “This is yet another initiative through which Vestas continues to implement its sustainability strategy,” said Kieran Walsh, senior vice president and head of construction at Vestas Northern & Central Europe. “There is a significant need for more sustainable solutions during these wind farms’ construction and operation phases. The potential for using SAF in offshore operations is high and we are pleased to further exploit this potential.”

The pilot project is scheduled to take place until September 2024. Helicopter service provider HeliService will use helicopters from Leonardo S.p.a. flying on about 40 percent SAF provided by DCC & Shell Aviation Denmark A/S. A blend rate of 40 percent SAF is close to the highest possible blend rate permitted today, and it is the first time that SAF-fueled helicopters with such a high blend rate are used for an entire part during the construction phase of an offshore wind-farm operation. CO2 savings of about 32 percent per flight are expected compared to using a standard helicopter powered by conventional jet fuel. Vestas will assess the impact of the SAF following the end of the pilot project.

The initiative is in line with Vestas’ sustainability strategy, which includes becoming carbon neutral in Vestas’ own operations by 2030 and reducing emissions in their supply chain by 45 percent per MWh generated. “The delivery of SAF to Roskilde Airport, which will serve as a helicopter base during Vestas’ pilot project, marks another milestone in our efforts to support the growing demand for alternatives to conventional jet fuel,” said Sune Petersen, head of strategy and sustainability at DCC and Shell Aviation Denmark.

“It also marks an initial step towards introducing SAF into the fuel mix for helicopter services — not only in Denmark but also on a European scale.”

Brittany wind farm turbine installation complete

Turbine installation at the Saint-Brieuc wind farm has been completed. The first offshore wind farm project in Brittany was recently commissioned with the connection of the first wind turbines to the French grid, producing clean energy for the 610,000 inhabitants of the Côtes-d’Amor territory.

This is possible thanks to the total installed capacity of 496 MW from 62 turbines, each generating 8 MW of power, which cover a surface area of 75 square kilometers 16 kilometers off the French coast, in the sector of the North Sea. With an investment of 2.4 billion euros, it is estimated to be capable of generating enough clean energy power to 835,000 people, which will make the territory a positive energy municipality by producing more electricity than it consumes. For another segment of the project, Sarens was also tasked with installing three tower sections of the turbine onshore on the construction tower frame (CTF).

After finalizing the towers, the installation vessel Brave Tern loaded four complete towers, blades, and nacelles for the offshore turbine installation. Brittany is prone to strong winds and high tides, which have shaped the region’s landscape, economy, and way of life. The completion of the first large-scale offshore wind farm in Brittany will help harness the region’s full energy potential.

Sarens to deliver base services for Moray West

Ocean Winds recently awarded SarensPSG with the contract to provide the intermediate delivery base services for the Moray West monopiles. The Moray West offshore wind farm in Scotland is a key part of the country’s energy transition and the path to net zero carbon emissions. The U.K. is constantly growing in new power generation capacity to maintain a secure and affordable supply.

Wind power is part of the solution, and Scotland, where renewable wind capacity exceeds 11 GW, already contributes 39 percent of the U.K.’s capacity. Wind generates 78 percent of all renewable electricity output in Scotland. “SarensPSG has unparalleled expertise, innovation, and commitment to drive positive change in the renewable energy landscape,” said Steve Clark, SarensPSG managing director.

“As the industry continues to evolve, SarensPSG remains at the forefront, proving to be the Sustainability Accelerator.” SarensPSG maneuvers took place in the port of Invergordon and involved the marshalling of 62 monopiles, each weighing up to 2,000 metric tons, the largest and heaviest XXL monopiles ever to be handled in the U.K., with diameters reaching up to 10 meters and a length extending to 84.7 meters.

That stage was recently completed using a self-propelled modular transporter of 166 axle-lines. The SPMT configuration comprised two sets of 80 axle-lines each, complemented by a 6-axle setup for smaller components. The selection of this equipment was determined by its flexibility, enabling transport and handling operations throughout the project. To handle the huge monopiles, the crew also devised strategic storage arrangements and sequencing methodologies to ensure efficient access to the monopiles during load-out.

Once operational, the Moray West Offshore Wind Project will contribute to the decarbonization of energy and help in creation of local employment opportunities, aligning with broader sustainability objectives.
