Green shipping: China Merchants to build emission-cutting propulsion system for UK-based BAR Tech
- The Chinese firm will manufacture WindWings, a wind-assisted propulsion and route optimisation system
- The system can save up to 1.5 tonnes of fuel per sail per day for a daily reduction of 4.9 tonnes in carbon-dioxide emissions

CM Energy Tech (CMET), a subsidiary of China Merchants, will manage and oversee the production of Portsmoouth-based BAR Tech’s wind-assisted propulsion and route optimisation system, called WindWings, in China.
“In looking at where we manufacture our WindWings, we recognised we have to align our production with the leading nations in global shipping construction,” BAR Tech CEO John Cooper said in a joint statement.
“China Merchants Group has many shipyards in their wider group, but this is about manufacturing for all the yards in the region and developing ever closer relationships.”

Hong Kong-listed CM Energy Tech is controlled by China Merchants Industry Holdings, a unit of state-owned transport-to-property conglomerate China Merchants Group. Its latest financial results showed it had generated US$92.9 million in revenue during the first six months of 2023, mainly from oil – rig manufacturing and supply chain services.
