The rotor sail technology comprised of vertical cylinders which, when driven to rotate, harness wind power to propel ships. The mechanical sails capitalise on the aerodynamic phenomenon known as the Magnus Effect to provide additional thrust to vessels and deliver fuel and emission savings.
“Our patented designs overcome operational constraints such as air draft and cargo handling, making the technology suitable for the majority of shipping sectors. As the industry focuses on emission reduction targets and energy saving, we are collaborating with Wartsila to strengthen our offering and facilitate the global uptake of our rotor sail by offering clients a full end-to-end solution including sales, supply and lifecycle support,” said Kim Diederichsen, ceo of UK-based Anemoi Marine Technologies.
The collaboration is expected to enable the adoption of wind assisted solutions for most marine vessel types, with the immediate focus likely to be on dry and wet bulk vessels. Wartsila said it will promote the solution for both newbuild projects and for retrofitting to existing ships.
Wartsila is also looking to integrate the rotor sail within its propulsion business. By offering wind propulsion solutions as an integral part of Wartsila’s propulsion offering, compliance with the IMO’s Energy Efficiency Design Index (EEDI) will be further facilitated.
Bernd Bertram, vice president, propulsion, Wartsila Marine Power, commented: “Wartsila is committed to fully supporting its customers by reducing their operating costs and reducing the environmental impact of their operations.”
