Mining giant BHP has become the latest major charterer to explore wind propulsion to cut emissions from shipping in partnership with Pan Pacific Copper (PPC) and Norsepower.

BHP and PPC, a member of JX Nippon Mining & Metals group, will retrofit a Norsepower rotor sail wind-assisted propulsion system on the 53,762-dwt combination bulk carrier Koryu (built 2013) operated by Nippon Marine.

The sail, a modern version of a Flettner rotor, will replace a crane on the geared vessel to reduce greenhouse gas emissions between BHP’s mines in Chile and PPC’s smelters in Japan.
