French liner giant CMA CGM is to retrofit up to 10 container ships with a variety of green technologies to reduce their carbon footprint.

The work, which will be carried out by Damen Shipyards Group, aims to deliver fuel efficiencies of more than 10%, the shipowner said.

The upgrades will take place at Damen Shiprepair Dunkerque and Damen Shiprepair Amsterdam, which between them have some of Europe’s largest dry docks.
