Lloyd’s Register grants AiP for Oldendorff Newcastlemax with Anemoi Rotor Sails

Lloyd’s Register has granted Approval in Principle (AIP) for an SDARI (Shanghai Merchant Ship Design and Research Institute) designed 210,000dwt Newcastlemax bulk carrier installed with Anemoi Rotor Sails to significantly improve efficiency and reduce environmental impact.

The Newcastlemax AIP is part of a pioneering joint development project (JDP), signed in 2020, with Anemoi Marine Technologies, Lloyd’s Register, and SDARI and brings together the OEM, classification society, ship designer, and ship owner to develop a series of energy-efficient vessel designs equipped with Rotor Sails. Oldendorff Carriers is the shipowner partner for this Newcastlemax design

Mark Darley, Global Marine and Offshore Director at Lloyds Register said:

“LR is committed to working together for a safe, sustainable and thriving ocean economy. 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.”

Director Innovation, Torsten Barenthin, of Oldendorff Carriers commented: “This has been an important project as part of Oldendorff Carriers’ commitment towards Getting to Zero. The results have demonstrated the impressive impact Rotor Sails have on regulatory obligations, which is a key consideration, in addition to the emission reduction benefits. We will continue our assessment of Anemoi’s technology for our fleet.”

The AIP covers 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.

Lloyd’s Register 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.
