Knud E. Hansen has designed three large RoRo vessels that will use electricity in port, courtesy of large lithium batteries, thus guaranteeing zero emissions whilst at berth.
The vessels' batteries will be recharged during navigation, through shaft generators employing a peak shaving system. Additionally, an innovative air lubrication system will be installed to reduce hull resistance using a thin layer of bubbles below the keel.
1A Super Ice Class
The vessels are based on the same hull as the Knud E. Hansen's Grimaldi Green 5th Generation vessels, but are customised according to Finnlines' requirements to be able to transport heavy cargo in a cold climate. The vessels will have a length of 238 metres, a beam of 34 metres, and are designed to meet the highest Finnish/Swedish ice class, 1A Super. The design is aimed to be flexible for all types of RoRo cargo with a capacity of 5800 lane metres and more than 5000 m2 of vehicle decks.
Nanjing Jinling Shipyard, China, will build the vessels that are to be delivered from 2021.
