Ocean Network Express (ONE) has announced plans for the long-term charter of the world’s largest containerships. They intend to charter six Ultra Large Container Ship newbuilds with capacity of more than 24,000 TEU, each for a period of 15 years. The newbuilding expected to be delivered in 2023 and 2024. With capacity exceeding 24,000 twenty-foot units, the new ships will likely be the largest in the world, just slightly larger than the current titleholders.
