Rotor Sails for world’s largest short sea ro-ro

The 2018-built MV Delphine, a vessel with a cargo capacity of close to 8,000 lane meters, transits between the UK, Ireland and Europe. With two 35m x 5m Rotor Sails, Norsepower has estimated that the technology would achieve a fuel and emission reduction saving of 7-10 per cent for this vessel, depending on the route.

The installation anticipated to be completed by December 2022.

The Norsepower Rotor Sail Solution is a modernised version of the Flettner rotor, a spinning cylinder that uses the Magnus effect to harness wind power to thrust a ship. At the time of contract signing, this will be the seventh vessel to be installed with Norsepower’s Rotor Sails.

Tuomas Riski, CEO, Norsepower, commented on the agreement: “Seeing the interest grow in our tilting Rotor Sail design demonstrates how the industry is looking for proven, flexible solutions to lower greenhouse gas emissions and reduce fuel costs across a range of vessel sizes and operations.

“Norsepower’s Rotor Sail installation on the MV Delphine demonstrates how the use of clean technology can modernise and evolve the performance of fleets’ younger vessels to manage emissions and help to increase asset value. With fuel becoming increasingly expensive, making savings will also have a huge impact on commercial success. Working with CLdN and its ambitious team is an opportunity to demonstrate what our technology has to offer to continue strengthening the environmental and commercial performance of its fleet.”

Gary Walker, COO Shipping, CLdN, added: “In 2021, CLdN announced it is the top performer amongst its Ro-Ro shipping peers in Northwest Europe for CO2 emissions per tonne of freight carried. By investing in technologically advanced ships and terminals, CLdN enables its customers to improve their carbon footprint and support them at the same time in making their supply chains more efficient and robust. This demand for cleaner shipping is growing and we are committed to making measurable progress. Installing two of Norsepower’s Rotor Sails will maximise our fuel and emissions savings on the MV Delphine, and this pilot project will help determine how the Rotor Sail technology could be rolled out on the current CLdN fleet and our new-build vessels. We look forward to the installation and subsequent results.”

On February 1, CLdN ro-ro signed a contract with Hyundai Mipo Dockyards for two hybrid 8,000 lane meter ro-ro vessels. The order forms part of CLdN’s long term growth plans and further strengthens its current role as greenest ro-ro operator in North-Western Europe. Both vessels will be delivered in the first half of 2025.

The Norsepower Rotor Sail is the first third-party verified and commercially operational auxiliary wind propulsion technology for the global maritime industry. The solution is fully automated and detects whenever the wind is strong enough to deliver fuel and emission savings, at which point the Rotor Sails start automatically. This is the third installation of the tilting Rotor Sail function, highlighting the growing interest in the flexibility of the latest design.

Earlier this year, Norsepower was granted Approval in Principle for its Rotor Sail technology solution from classification society, RINA.

Kongsberg Maritime has added Norsepower’s Rotor Sail wind propulsion to its integrated power and propulsion systems.
