Lloyd’s Register (LR) has granted Approval in Principle (AiP) for a SDARI (Shanghai Merchant Ship Design and Research Institute) designed 210,000 DWT Newcastlemax bulk carrier that is fitted with Anemoi Rotor Sails to improve efficiency and reduce environmental impact.
The AiP is part of a joint development project (JDP), signed in 2020, with Anemoi Marine Technologies, Lloyd’s Register, and SDARI. Oldendorff Carriers is the shipowner partner for this Newcastlemax design.
The fitting of Rotor Sails on this bulk carrier, as part of our JDP with Anemoi, SDARI and Oldendorff Carriers, will considerably improve the vessel’s efficiency and is a clear example of how energy saving devices can support the maritime industry with impending EEXI and CII regulations
stated Mark Darley, Global Marine and Offshore Director at Lloyds Register.
The AiP regards the structural integration for a ship design with six 5x30m Rotor Sails and Anemoi’s Rail Deployment System, which sees the Rotor Sails move transversely across the deck to avoid inference with cargo handling; and the structural integration for a ship design with four of Anemoi’s folding (tilting) 5x35m Rotor Sails.
As for Lloyd’s Register, it has assessed the calculation used to estimate the impact the Rotor Sails will have on the Energy Efficiency Design Index (EEDI) and validated that the newbuild Newcastlemax would have its EEDI score reduced from 1.92 to 1.37 (29% reduction) by installing six 5x30m Rail Rotor Sails and 1.47 (23% reduction) by installing four 5x35m Folding Rotor Sails.
