Anemoi Marine Technologies Ltd (Anemoi), a prominent leader in wind-assisted propulsion systems, has achieved a significant milestone by receiving the Type Approval Design Certificate (TADC) from classification society DNV for its innovative Rotor Sail design. The design in question measures 5 metres in diameter and 35 metres in height, further reinforcing the company’s dedication to enhancing sustainable shipping solutions.
The TADC was formally presented to Anemoi during a special ceremony at the renowned SMM maritime trade fair held in Hamburg, Germany, on 5 September 2024. The certification validates that Anemoi’s 5x35m Rotor Sail design complies with DNV’s technical standard (ST-0511) for Wind Assisted Propulsion Systems (WAPS), ensuring that it meets rigorous industry standards.
This achievement marks an important milestone for Anemoi, as the certification provides shipowners and operators with the assurance they need when considering investment in the company’s wind-assisted propulsion technology. The 5x35m Rotor Sail design has already garnered significant interest, with several installations scheduled for upcoming vessels.
Kim Diederichsen, CEO of Anemoi, expressed the company’s pride in this accomplishment “We are delighted to have received this important Type Approval from DNV, which is a testament to the rigorous design and engineering work undertaken by our team. This certification provides shipowners and operators with the assurance they need to invest in our 5x35m Rotor Sail solution, which has already been selected for upcoming installations on several vessels.”
Collaboration with DNV
The partnership between Anemoi and DNV has been pivotal in the development of wind-assisted propulsion technologies. Hasso Hoffmeister, Senior Principal Engineer at DNV Maritime, highlighted the importance of this certification and the broader context of WAPS growth “Over the last few years WAPS technologies have continued to go from strength to strength, with the number of installations tripling in just the last year according to estimates from the IWSA. This growth has been built on innovation, safety, and trusted expertise. We are very pleased to build on the excellent collaboration with Anemoi with the presentation of this certificate. Together we are continuing to develop the technical standards and class notations that will enable the momentum behind WAPS to continue to build and enhance shipping’s drive to greater sustainability.”
First Commercial Deployment: Berge Neblina
In May 2024, Anemoi’s 5x35m Rotor Sail was successfully installed on the DNV-classed bulk carrier Berge Neblina, owned by Berge Bulk. This installation represents the first commercial deployment of this specific Rotor Sail size and is expected to significantly enhance the vessel’s energy efficiency. The use of Rotor Sails helps reduce fuel consumption by capitalizing on wind energy, leading to reduced greenhouse gas emissions without compromising speed.
Looking ahead, Anemoi has additional installations planned for later in 2024 and into 2025. Notably, the Sohar Max, a 400,000 DWT Very Large Ore Carrier (VLOC) operated by Vale, will also be fitted with the 5x35m Rotor Sails. This reflects growing industry interest in wind-assisted propulsion solutions, especially as the sector moves toward decarbonization.
Rotor Sails: Harnessing the Power of Wind
Rotor Sails, also known as Flettner Rotors, are vertical cylinders that, when rotated, harness the power of wind through the Magnus Effect to provide additional thrust to ships. By utilizing wind energy, vessels can reduce the power needed from their main engines, resulting in lower fuel consumption and a significant reduction in emissions such as CO2, SOx, and NOx.
This technology is increasingly being adopted by shipowners, particularly in the bulk carrier and tanker sectors, as it helps meet global emission reduction goals. Rotor Sails are compact and offer a large thrust force with minimal impact on the vessel’s visibility, stability, and port operations. They also help vessels comply with international regulatory benchmarks such as the Carbon Intensity Indicator (CII) and the Energy Efficiency Design and Operational Indexes (EEDI/EEXI).
Future of Shipping with Anemoi
As the global shipping industry continues its push towards sustainability, Rotor Sails are seen as an essential part of reducing carbon emissions and creating more efficient vessels. Anemoi’s latest certification further cements its position as a leader in this space, with its products poised to play a key role in transforming the energy efficiency of the global merchant fleet.
