AP Moller-Maersk has put pen to paper on a newbuilding order for 10 methanol dual-fuel 9,000-teu container ships worth $1.15bn.

Shipbuilding sources said the liner giant has commissioned Singapore-listed Yangzijiang Shipbuilding to construct six firm ships, with options for two to four more.

Maersk’s plans to order methanol dual-fuel neo-panamaxes were first reported in TradeWinds in May.
