Maersk Supply Service and Stiesdal Offshore forge floating alliance

Maersk Supply Service and Stiesdal Offshore have entered into a strategic partnership to offer combined solutions to the floating offshore wind market. The two Danish companies intend to create engineering, procurement, construction and installation (EPCI) solutions for foundations and moorings.

Since 2017, Stiesdal Offshore has been developing its fully industrialised floating Tetra concept. Based on factory-made modules assembled in port to form a complete foundation, the Tetra concept aims to reduce manufacturing hours and offer a lightweight and cost-effective floating foundation. In cooperation with Shell, RWE and TEPCO Renewable Power, Stiesdal built and installed the first Tetra floater off the west coast of Norway in 2021.

Maersk Supply Service delivers integrated solutions for the offshore energy sector worldwide. It outlined that the move into floating wind is therefore a natural progression for the company, combining its project management expertise, engineering and technical capabilities with a versatile fleet. Most recently, Maersk Supply Service oversaw and executed the mooring system installation for the Saitec DemoSath floating wind project offshore Bilbao.

By establishing Maersk Supply Service and Stiesdal Offshore as a joint solutions provider, they aim to offer full-scope EPCI services to floating wind farm developers looking to scale their projects from demonstrations to full commercial operation.


Project opportunities will be deemed within the scope of the collaboration when they comprise of integrated floating wind solutions, including the engineering and design element of offshore floating wind structures. Maersk Supply Service will act as lead contractor and key contact for clients on any projects carried out as part of the collaboration, with Stiesdal Offshore acting as a subcontractor to Maersk Supply Service.

“With this partnership, we want to offer our customers a combined EPCI solution for floating wind foundation design, fabrication, assembly and installation. We believe this will simplify the value chain in the growing floating wind sector, which is still in the early stages, but which will also by necessity see rapid expansion and growth in the coming decade. By working closely together with Stiesdal, we want to facilitate this green development – and to accelerate our own journey into floating wind,”
said CEO of Maersk Supply Service, Steen S. Karstensen.

“Maersk Supply Services is a global operator with decades of world-leading marine services to its name. Stiesdal has the technologies for developing competitive floating offshore wind on a truly global scale. I am confident that with the combined capabilities of the two companies we can fulfil a significant share of the ambitious targets being set for floating wind in the coming decade,”
said Stiesdal CTO Henrik Stiesdal.
