Subsea Micropiles has completed the installation of its first commercial drilled and grouted “micropile” anchor solution for Orkney Harbour Authority (OHA) in Scotland, following more than £10 million in research and development.
The project marks a milestone for the UK-based firm, which has adapted micropiling technology—traditionally used in onshore construction—for offshore applications, including fixed and floating wind structures. The foundation system is designed to support high load capacities across varied soil conditions, offering a scalable solution for marine infrastructure.
Jim Buck, Harbourmaster at Orkney Harbour Authority, described the technology as having “exceptional potential” to support Scotland’s offshore wind ambitions.
“The technical solution that has been developed by Subsea Micropiles has exceptional potential to become critical infrastructure for floating offshore wind in Scotland,” Buck said. “The Orkney Harbour Authority is pleased to become an ‘early adopter’ in order to support innovation like this in the marine industry.”
OHA plans to assess broader use cases for the anchoring system, including mooring for its tug fleet and offshore renewable energy developments.
Subsea Micropiles CEO Derek Robertson highlighted the installation as a breakthrough for the company and its engineering team. “I am very proud to recognise the pioneering achievements of our team who are introducing a full-solution and service capability to the market,” he said.
Robertson noted that the company’s progress has been supported by collaboration with Irish drilling specialist Mincon, which contributed to the development of high-performance subsea drilling tools.
“We have invested heavily in the design of micropiled structures, development of new subsea drilling equipment, and the implementation of highly productive drilling technology,” he added. “I am grateful for the interest and outstanding support from OHA as well as our suppliers in Orkney and beyond.”
The company said the micropile system is intended to offer a reliable, efficient, and adaptable foundation option for marine industries under pressure to meet infrastructure demands in offshore wind and other sectors.
