To support and accelerate floating wind's development, the two Danish companies intend to combine their respective strengths to create comprehensive and integrated engineering, procurement, construction and installation (EPCI) solutions for foundations and moorings. This integrated approach will streamline the value chain, facilitating fast-track installations and ultimately bringing down the levelized costs of floating wind, Maersk said.
Since 2017, Stiesdal Offshore has been developing the Tetra concept, the world’s first fully industrialized floating technology. Based on factory-made modules assembled in port to form a complete foundation, the Tetra concept reduces manufacturing hours significantly, achieving a lightweight and cost-effective floating foundation, the company said.
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, demonstrating the cost-saving and rationalization potential of the concept.
From the EPCI side, Maersk Supply Service delivers integrated solutions for the offshore energy sector worldwide. Its core capabilities are delivering towing and mooring scopes in some of the harshest waters. 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.
The aim of this collaboration is to leverage the companies’ combined strengths and assets to accelerate the rollout of floating wind. By establishing Maersk Supply Service and Stiesdal Offshore as a joint solutions provider, they can offer full-scope EPCI services to floating wind park developers looking to scale their projects from demonstrations to full commercial operation. This collaboration enables seamless interfacing between foundation design, fabrication and assembly execution, and offshore installation. Through pre-existing, fully worked out base solutions, the partnership will allow faster and more robust optimization for specific project needs and will facilitate shorter overall project durations, reduced working capital cycles, smoother foundation fabrication to installation and overall reduced risk and improved project delivery, the companies said.
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.
