The barge will also have features that prepare her for unmanned operation. The first five small ships will be completed this year and six larger vessels are planned. The smaller barge, which has one battery, will carry 24 teu, while the larger version will be able to carry 224 teu and have four battery packs.
For power, the barges will use containerised battery packs, which can either be recharged or exchanged at the terminal, allowing rapid turn-round times. Werkina said the larger barge will be able to carry about eight per cent more cargo than a standard barge as they will not need as much space for an engine room.
The barges will be fitted with a retractable wheelhouse that can be lowered to pass under bridges.
