BHP has partnered with Pan Pacific Copper (PPC), a member of JX Nippon Mining & Metals group, and Norsepower, the leading global provider of auxiliary wind propulsion systems, to reduce greenhouse gas (GHG) emissions from maritime transportation between BHP’s mines in Chile and PPC’s smelters in Japan, reports International Mining.
Technical assessment and retrofit installation
The parties are conducting a technical assessment and plan a retrofit installation of wind-assisted propulsion system onboard the M/V Koryu, a combination carrier operated by Nippon Marine – a member of SENKO group (shares held by SENKO 60%, JX Nippon Mining & Metals 40%).
BHP and PPC have multi-year agreements for delivery of copper concentrates from Chile to Japan as well as sulphuric acid from Japan to Chile, making the cargo capacity utilization of M/V Koryu (a 53,762 deadweight tonne combination carrier) one of the highest in the industry.
Push-button wind propulsion
Norsepower’s Rotor Sails installation – a “push-button wind propulsion” system and estimated to be around ten times more efficient than a conventional sail that requires no reefing or crew attention when in operation – is scheduled for completion by the third quarter of 2023, which is expected to make M/V Koryu the cleanest vessel in its category when measured for GHG emissions intensity.
Norsepower’s Rotor Sails are modernized versions of Flettner rotors, and the technology is based on the Magnus effect that harnesses wind to maximize ship fuel efficiency. When wind conditions are favorable, Rotor Sails allow the main engines to be throttled back, saving fuel and reducing emissions, while also reducing power needed to maintain speed and voyage time.
Achieving maritime decarbonization
This latest partnership with PPC and Norsepower follows BHP’s collaboration agreements in the maritime decarbonisation segment that includes the first marine biofuel trial involving an ocean-going vessel bunkered in Singapore, taking delivery of the first of five LNG-fuelled Newcastlemax bulk carriers and joining a consortium to assess the development of an iron ore Green Corridor between Australia and East Asia. BHP is also a founding member of the Global Maritime Decarbonisation Centre in Singapore.
JX Nippon Mining & Metals group has declared the target of net-zero CO2 emissions by fiscal 2050 and is further accelerating its action to reduce CO2 emissions of Scope 3 including raw material production and logistics throughout the entire supply chain. Also, on 3rd August, JX Nippon Mining & Metals released “Sustainable Copper Vision”. Joining this partnership is a part of the activities of “Reduce Copper’s Carbon Foot Print (CFP)” that is one of the “Four Initiatives” committed to take.
