Liberian Registry awards AiP to Anemoi’s rotor sails

The Liberian Registry has awarded an Approval in Principle (AIP) to Anemoi Marine Technologies for their Rotor Sail systems.

Anemoi’s Rotor Sails are available with three deployment options - fixed to the deck, a folding type, and on rails that can be moved along or across the deck.

The folding and rail systems were validated on a Newcastlemax bulk carrier design from SDARI and issued an AIP by Lloyd’s Register.

The Liberian Registry conducted a technical review of the documentation including Energy Efficiency Design Index (EEDI) calculations and, as a result, issued an AIP with estimated energy efficient improvements of about 20% in terms of EEDI performance.

Anemoi Rotor Sails were created to accelerate the industry’s transition to zero emission shipping by providing auxiliary propulsion to a vessel – this maintains vessel speed but allows the main engine to be powered down, resulting in fewer emissions.

Rotor Sails address new IMO environmental requirements for Carbon Intensity Indicator (CII) rating and Energy Efficiency Existing Ship Index (EEXI), which went into effect 1 January 2023 and are driving the need for the global fleet to continuously decarbonize, the goal being to reach zero-emission in line with the UN Paris Agreement.

“The Liberian Registry is extremely pleased with the collaboration with Anemoi, LR and SDARI to review and validate Anemoi’s Rotor Sail technology that have demonstrated an up to 20% energy reduction. Wind propulsion’s comeback to the merchant fleet is much welcome and true win-win situation,” said Thomas Klenum, Executive Vice President, Innovation & Regulatory Affairs at LISCR.

Kim Diederichsen, Chief Executive Officer, of Anemoi, said: “This collaboration is a great example of organisations working together to create a brighter future for the maritime industry. The Liberian Registry have demonstrated their commitment to zero emission shipping by supporting Rotor Sail technology as a recognised solution. We are very pleased to receive this acknowledgement from a leading flag state and look forward to a long-standing relationship.”
