Singapore-based dry bulk owner Berge Bulk has contracted Anemoi Marine Technologies Ltd to supply and fit two vessels in their dry bulk fleet with Anemoi Rotor Sails. It concerns the Berge Neblina and Berge Mulhacen.
The first vessel, Berge Neblina, a 388k DWT Valemax ore carrier built in 2012, was made “wind-ready” earlier this year. The structural integration required prior to installing the technology was carried out during a scheduled dry dock. Four of Anemoi’s large folding deployment Rotor Sails will be installed to improve vessel performance. Folding Rotor Sails can be lowered to mitigate the impact on air draught and cargo handling operations.
The Berge Mulhacen, a 2017-built 210k DWT Newcastlemax bulk carrier, will also receive four folding Rotor Sails. Plan approval has been obtained for both ships from DNV. Berge Bulk wants to develop and deploy commercially viable deep-sea zero-emission vessels by 2030.
‘We’re committed to continuous innovation and exploring cleaner, greener energy sources,’ says Paolo Tonon, Technical Director at Berge Bulk. ‘Wind propulsion is an option we have explored previously in other formats, and we firmly believe it can help achieve our decarbonisation commitments. The partnership with Anemoi commenced with in-depth engineering simulations to find the best possible technical and commercial solution. Therefore, we are pleased to be rolling out their Rotor Sail technology on our vessels.’
Rotor Sails are large mechanical sails that harness the renewable power of the wind to reduce emissions and fuel consumption on commercial ships when driven to spin. Anemoi predicts that the four-rotor system will save Berge Bulk 1200 to 1500 metric tonnes of fuel per vessel each year.
