AP Moller-Maersk is in the process of signing newbuilding orders for between 50 and 60 vessels.
The giant liner operator is inking contracts and time charters for dual-fuel vessels to match a renewal pace of around 160,000 teu per year.
That is designed to help the company maintain its competitive edge and decarbonise its operations, said Maersk chief operating officer Rabab Boulos.
