LLoyd Fonds says the newbuildings belong to a new generation of containerships, whose dimensions are already designed for the forthcoming enlargement of the Panama Canal. They will have a capacity of 1,000 FEU reefer containers.
The ships will be built to Germanischer Lloyd class and will have a length of 365.6 m, a breadth of 48.4 m and a main machinery output of 68.520 kW (93,120 hp).
How do their dimensions stack up against the world's largest containership. Emma Maersk? Though the Lloyd's Fonds ships have a larger stated TEU capacity, 12,800 TEU, against the Emma's 11,000 TEU, they will actually be somewhat under the Emma's 397 m length and 56 m beam and will have less power than the Maersk ship's 80,800 kW.
In other words, Emma Maersk and its sisters still hold the the "world's largest" crown (and would have a TEU capacity of upwards of 13,500 if Maersk calculated capacity the way everyone else does).
