train system, offering unmatched energy efficiency and an
extremely compact lightweight design, yet providing the
required 1.5 MW propulsion power necessary to operate the
E-ferry at the speed of 14.5 kts. The overall electrical system
is based on Visedo’s DC/DC converter technology and by
charging the system directly with DC power, placed on shore,
reducing the total weight by 20 tonnes.

Søby Shipyard and Naval Architects are jointly optimizing
the performance of the entire vessel through an optimized
hull-shape while Tuco Marine Group and The Danish
Institute of Fire and Security Technology have joined forces
to investigate the degree to which lightweight composite
materials can be safely implemented in the E-ferry. On the
safety side, Leclanché has been working for months on the
certification of its entire Marine Rack System to meet the
highest standards of the Danish Maritime Authority and DNV-
GL (Certification in process).

Altogether, the E-ferry is a state-of-the-art vessel on every
aspect of its design and construction. The environmental
goals foreseen target reductions in CO2 emissions by
approximately 2.000 tonnes, NOX by 41.500kgr, SO2 by
1.350kgr and particulates by 2.500kgr per year. l
