MAN Energy Solutions will supply six MAN B&W 9S50ME-C9.6 Tier II-compliant main engines for three, 238-metre RoRo vessels intended for operation in the Baltic Sea for Finnish shipping company Finnlines.
The MAN B&W ME-C engines will form part of the hybrid propulsion set-up and enable a 100% increase in efficiency when measured in terms of consumption/ton of freight transported, compared to existing vessels.
Designed by Nordic marine designer, Knud E. Hansen, the new RoRos will be among the first examples of a new series of hybrid vessels. These will use fuel-oil during navigation and lithium mega-batteries in harbour, guaranteeing zero emissions in port.
The batteries will be recharged during navigation through shaft generators adding the so-called peak-shaving system.
Bjarne Foldager, senior vice president and head of two-stroke business at MAN Energy Solutions, says, “These new RoRos will be among the most environmentally sustainable ships of their type. Finnlines is a frontrunner in the development of hybrid power ships, of marine battery packs and of energy-management systems. By investing in research and development and by teaming with its suppliers, Finnlines is well on time to meet and clearly exceed all the ambitious environmental targets set by the IMO.”
MAN Energy Solutions’ two-stroke licensee; Hyundai Heavy Industries will build the engines in Korea, while Nanjing Jinling shipyard in China will construct the vessels. Delivery of the first vessels is expected from 2021.
