Brunvoll to supply propulsion for Purus Wind CSOVs

Each vessel will be outfitted with two azimuth thrusters for propulsion, and two retractable azimuth thrusters and a tunnel thruster for manoeuvring. The scope of supply features also Brunvoll’s propulsion and thruster control system, BruCon PTC.

“The offshore wind market will be an important segment for Brunvoll in the coming years, and with these additions to our orderbook we already have good visibility for factory use in 2024,” said Kåre Øyvind Vassdal, chief executive at Brunvoll Group.

The propulsion thrusters are said to feature improved azimuth rotation speed, increased propeller acceleration/deceleration, and increased thrust efficiency in terms of reduced thruster and hull interaction.

The vessels, which are of VARD 4 19-design, are approximately 87m by 19.5m and can accommodate 120 crew. Delivery is scheduled for Q2 2025 and Q2 2026 with the first being built at one of Vard’s yards in Norway and the second by Vard Vung Tau in Vietnam.

Vard and Brunvoll’s partnership dates back more than 80 years. “The chosen solution in this project is an optimisation from both Vard Design and Brunvoll, and it will give better operability and lower emissions,” said Runar Vaagnes, senior vice president, Sales & Marketing at Vard..
