Anemoi installs four folding rotor sails on Berge Bulk’s Newcastlemax in second joint project

Berge Bulk has pushed further into wind-assisted propulsion with the completion of four folding rotor sails on its 208,000 dwt Newcastlemax Berge Meru, marking a second large-scale retrofit with Anemoi Marine Technologies Ltd, according to the companies’ statement. 

The 5-metre diameter, 35-metre-high units were installed at Yiu Lian Dockyards in China in December 2025. The bulker has now returned to service, completing its first post-installation voyage to Singapore.

The system is designed to deliver auxiliary thrust by harnessing wind energy, cutting fuel burn and associated emissions on ocean passages. 

BERGE MERU follows the June 2024 retrofit of sister technology on the Valemax Berge Neblina, the first vessel in the owner’s fleet equipped with Anemoi rotor sails.Operational experience from that project and ongoing in-service performance monitoring fed directly into the Newcastlemax installation as Berge Bulk accelerates deployment of what it sees as scalable decarbonisation tools. The folding configuration allows the sails to be lowered for port stays and height restrictions. In heavy weather, thrust generation can be shut down without physically lowering the structures.

Anemoi chief executive Clare Urmston said the repeat project showed wind propulsion could be integrated into large commercial bulkers in a practical and operationally flexible manner, adding that Berge Bulk’s continued commitment underlined confidence in the technology.

Anemoi Marine Technologies Ltd develops and supplies rotor sail wind propulsion systems for commercial shipping, focusing on retrofit and newbuild applications designed to reduce fuel consumption and atmospheric emissions through wind-assisted thrust.

Berge Bulk is an international dry bulk shipping company operating a diversified fleet across major vessel classes, with a strategic focus on efficiency improvements and technologies aimed at lowering the environmental footprint of bulk transport.
