At a recent online media conference, CEO Jeremy Nixon said 150,000 TEU of newbuilding investments would be made annually to 2030.

He added: "We're just starting to order ships as ONE. We have leased 38 vessels, which will be deployed from 2023 to 2025, and that's about 500,000 TEU.

"That process will replace ships due to come off-charter and help to improve our overall efficiency in slot costs and reduce our carbon footprint." Ships on long-term lease comprise six of 24,000 TEU, 14 x 15,000 TEU, eight x 12,000 TEU and 10 x 7,000 TEU.

ONE is said to be in the process of finalising orders for ten 13,000 TEU ships to be equally split between Imabari Shipbuilding in Japan and Hyundai Heavy Industries in South Korea.

Mr Nixon said: "Last year, 75 per cent of our fleet was chartered from our shareholders and, by 2030, this will be reduced to 20 per cent, this is why we need to replenish our future ship requirements."

The newbuildings could be fuelled by hydrogen, ammonia or methanol, to align with the company's green strategy, he added.

ONE's investments in container terminals will involve transferring assets from its parent liner companies. Formed in 2017 of the container businesses of MOL, NYK and K Line, Japan's biggest shipping groups, ONE was intended to build synergies to overcome the difficult conditions in the container market at the time.

Mr Nixon noted that, after a loss in ONE's first year of operations, the company had been profitable ever since, and a net profit of $15.4 billion is expected for fiscal year ending March 31 - a near five-fold increase on the net profit of $3.48 billion achieved in FY 2020.
