Anemoi, NAPA team up to reap fruits of rotor sails combined with voyage optimization

The UK-based wind-assisted propulsion provider Anemoi Marine Technologies has signed an agreement with NAPA, the Finnish-based global maritime software, services and data analysis expert, to bring its weather routing and voyage optimization tools to users of its rotor sails.

As informed, the partnership between the two maritime technology companies will enable all vessels fitted with Anemoi’s rotor sails to access critical weather and voyage optimization data, enabling shipowners and operators to choose routes that will increase the performance of vessels equipped with wind-assisted propulsion systems (WAPSs) and reap the maximum fuel savings and emission reductions possible.

Under the terms of the agreement, NAPA software will be included as an option in all future sales of Anemoi’s rotor sails, including both newbuilds and retrofits.

Specifically, NAPA Voyage Optimization software generates tailored route suggestions based on the unique 3D performance model of each vessel including sail configurations., By integrating weather routing, route networks, and port data, the software proposes routes that account for wind speeds, wave conditions, currents, water depth, and safety parameters. This data-driven approach empowers ship captains to select voyage routes that enable onboard rotor sail technology to work at its maximum efficiency.

Rotor sail technologies are increasingly being sought after by vessel owners as a critical energy-saving technology in order meet international emission reduction targets, including the Energy Efficiency Design Index (EEDI), Energy Efficiency Existing Ship Index (EEXI), and the Carbon Intensity Indicator (CII). Anemoi’s rotor sails have been shown to save up 30% in harmful carbon emissions from vessels operating on routes that have good wind conditions.

“Our partnership with NAPA is yet another step in improving the efficiency and effectiveness of our Rotor Sails for global shipowners. Crucially, it shows the importance of how data can be used to improve the decarbonisation efforts of global shipping. Anemoi has long advocated for the combination of wind-propulsion technology and data through our Fuel Saving Assessment methodology to accurately predict fuel and emissions savings. This latest collaboration will take this data-driven approach to decarbonisation to the next level,” Kim Diederichsen, CEO of Anemoi Marine Technologies, commented.

“This partnership with Anemoi exemplifies NAPA’s commitment to leveraging advanced data analytics to drive maritime efficiency and sustainability. By integrating NAPA Voyage Optimization software with Anemoi’s Rotor Sails we equip shipowners and operators with the necessary tools to fully harness wind power for greater efficiency and sustainability,” Mikko Kuosa, CEO of NAPA, said.

In related news, Anemoi Marine Technologies recently installed four rotor sails onboard Berge Neblina, a 388,000 dwt Valemax ore carrier owned by Singapore-based shipping company Berge Bulk.

The four 5x35m rotor sails have been installed on Anemoi’s folding deployment system, whereby the sails can be folded from the vertical to mitigate the impact on air draught and cargo handling operations when in port. With the newly installed Rotor Sails, Berge Neblina is expected to save more than 1,000 tonnes of fuel annually, according to Berge Bulk.
