Norsepower Oy Ltd., the world’s leading supplier of auxiliary wind propulsion systems, has signed a formal agreement with NAPA, the global expert in maritime software, services and data analysis, to offer weather routing software in combination with its solution Rotor Sails.


Under the agreement, NAPA Voyage Optimization software will be included as an option on all future sales of Norsepower’s Rotor Sails solution. The combined offer, which applies to both retrofits and new builds, will allow shipowners to maximize both fuel savings and emissions reductions. The combination of travel optimization and wind propulsion offers significant potential for increased performance over either technology alone. The software determines the best possible voyage plan for the vessel to maximize energy savings, taking into account weather conditions throughout the voyage as well as each vessel’s design profile and operational requirements.


The Norsepower Rotor Sail Solution is a modernized version of the Flettner rotor, a rotating cylinder that uses the Magnus effect to harness wind energy and generate thrust, reducing fuel consumption and emissions by an average of 10-25% . The solution has so far been installed on six different vessels, with further orders confirmed with CLdN, the logistics specialist for road, sea and rail.


The NAPA Voyage Optimization solution allows captains and ship managers to choose routes that will minimize their fuel consumption and emissions, depending on weather conditions. Importantly, the suggested routes are tailored to each vessel’s designs and characteristics, using vessel-specific numerical models to assess and predict performance under different conditions. This will ensure that Norsepower’s Rotor Sails system is specifically considered in vessel performance models to provide optimum routing.


Tuomas Riski, CEO of Norsepower, commented on the partnership: “Our rotor sails already offer fuel and associated emissions savings of up to 25%. However, the savings can be significantly improved when used with weather routing software. Given the scale of the energy transition challenge, the combination of commercially proven solutions enables shipowners to take the next step to not only meet regulatory targets, but exceed them. Ships using the solutions available today will be able to decarbonize faster. It will also help shipowners achieve better climate alignment compliance scores, including the IMO’s Carbon Intensity Indicator (CII), as well as support ship finance portfolios that are influenced by the requirements of guidelines such as the Poseidon Principles and sea freight charter clauses. We are proud to partner with NAPA to enhance our offering to our customers with this turnkey solution that will help them achieve optimal results with our well-established Rotor Sails.


Pekka Pakkanen, Executive Vice President of NAPA Shipping Solutions, added, “Advanced weather routing is essential for all ships, but is especially important for wind-assisted ships. Now that wind propulsion solutions are becoming a reality for an increasing number of ocean-going vessels, we are taking it to the next level with voyage optimization software that can fully model various clean technology solutions in all weather conditions, taking into account the design data for each individual vessel. This is made possible by our decades of expertise in naval architecture and vessel performance monitoring. We are excited to partner with Norsepower to help more companies around the world realize their sustainability ambitions with this powerful combination of technologies. »
