Low (Zero) Emission Feeder - the latest Nelton’s creation is a medium-sized container ship whose purpouse is to transport goods on short routes between ports in the Baltic and North Sea basins. Armed with developed study of European shipping routes, we conducted optimization which resulted in the concept: Tri-Brid, i.e. powered by three different energy sources container ship - a recipe for ECA and significant step towards cleaner, quiet & eco-friendly port cities of Europe. Built-in batteries with a substantial capacity will be placed above engine room. More energy banks necessary to perform designated tasks in the emission - free mode will come from exchangeable battery containers. Both banks combined are about providing essential power on a scale never seen in shipping industrie. As Baltic and North Sea are wind-rich regions aft of the ship will be equiped with two VAWTs whose task is - coupled with multiple GenSets to charge the batteries on cruises & at the quay.
