Venterra Group Supporting Construction of Sofia Offshore Wind Farm
1 August 2025: Venterra Group company Partrac, a leader in metocean survey and monitoring solutions, marks two years of successful deployment supporting RWE, one of the world’s leading offshore wind companies, on the landmark Sofia Offshore Wind Farm, one of the world's largest and most ambitious offshore wind projects.
Located 195 km northeast of the UK's coast, on Dogger Bank, the Sofia Offshore Wind Farm is a flagship project in the country's transition to renewable energy. It will feature 100 Siemens Gamesa turbines, each standing 252 meters tall, and will cover a total area of 593 square kilometres. Once completed, Sofia is set to become one of the largest and most remote offshore wind farms ever constructed.
Trusted Partner in Critical Infrastructure Delivery
Since May 2023, Partrac has been instrumental in the construction phase, deploying a network of metocean measurement and demarcation buoys. This includes the installation of Cardinal Mark and Special Mark buoys to define the site's perimeter, as well as wave buoys that provide real-time environmental data essential for safe and efficient construction planning and management.
Partrac's advanced online client portal provides real-time wave and current data to RWE and project stakeholders, facilitating informed decision-making and supporting the safe, efficient, and timely execution of this complex infrastructure project.
Demonstrated Capability and Technical Excellence
Partrac's successful delivery on the Sofia Offshore Wind Farm (OWF) project demonstrates its market-leading capabilities in supporting large-scale and technically complex offshore projects for major energy clients. The company's expertise in deploying, maintaining, and recovering critical infrastructure in demanding offshore environments establishes Partrac as a trusted partner for the world's most prestigious renewable energy developers.
"Supporting the construction of the Sofia Offshore Wind Farm over a period of several years showcases Partrac's technical expertise and operational reliability,"
stated Sam Athey, Managing Director of Partrac.
"Whilst our success in this market has traditionally been based on our services around early-stage metocean surveys and monitoring, we are now seeing an increasing number of clients worldwide engaging us to support the construction phases of their development projects including the development of offshore substations and the installation of submarine infrastructure for energy and communication projects. We are proud to work with RWE on this and other offshore wind projects."
With Sofia OWF nearing completion, Partrac's continued delivery of safe and high-quality services supporting complex, large-scale projects and leading players, such as RWE, yet again confirms Partrac's position at the forefront of the offshore wind sector.

Sofia
The 1.4 gigawatt (GW) Sofia Offshore Wind Farm, sited on the shallow central area of the North Sea known as Dogger Bank, is the largest offshore wind project in RWE's current portfolio. The project is located 195 km off the UK’s Northeast coast on a site of 593 square kilometres. It has an agreed connection point at an existing National Grid substation in Lackenby, Teesside. Sofia Offshore Wind Farm is one of the four Dogger Bank projects that were awarded consent in 2015. Formerly known as Dogger Bank Teesside B, the entire project was taken over by innogy (now RWE) in August 2017 and subsequently renamed Sofia Offshore Wind Farm.
RWE currently operates 10 offshore wind farms across the UK, with an additional nine in development. These development projects represent a combined potential installed capacity of approximately 9.8 GW, with RWE’s pro-rata share totalling 7 GW.
