The two companies plan to offer engineering, procurement, construction and installation (EPCI) services for floating offshore wind.

They hope to streamline the floating offshore wind sector’s value chain, accelerate installations and reduce costs.

Through the partnership, Maersk Supply Service will serve as lead contractor and key contact for clients, with Stiesdal Offshore acting as its subcontractor.   

Maersk Supply Service CEO Steen Karstensen said: “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.” 

Stiesdal Offshore is already established in the floating wind industry. It has been developing the TetraSpar concept since 2017, a technology based on factory-made modules which are assembled in port to form a complete floating foundation. It connected a 3.6MW demonstration project backed by Shell, RWE and Tepco to the Norwegian grid late last year.

Meanwhile, Maersk Supply Service has more than 50 years’ experience of towing and mooring in offshore oil and gas. However, it is looking to transition to floating wind, describing the move as a “natural progression”.

It recently installed the mooring lines for Saitec and RWE’s DemoSATH floating wind pilot off the coast of Bilbao, Spain.
