Electrifying world class cruise ships with giant induction motors
fident that GE's proven electric propulsion technology is the ideal
choice for our fleet, " said Emilio LaScala, president & managing
director at MSC Cruise Management Ltd. " It will bring reduced
operating costs and improved propulsion performance, ideally
suited for our next generation of cruise vessels. "
Advanced electric propulsion from GE powers MSC Europa cruise ship
Shipbuilding company Chantiers de l'Atlantique chose GE Power
to equip the first two of the World Class vessels, MSC Cruises'
latest class of ships, for improved propulsion performance. The
first ship, MSC World Europa, is now in operation at sea and
the second vessel is currently in build. This latest one marks
the 18th MSC vessel to be powered by a GE electric propulsion
system. Its energy-efficient PWM induction technology, such as
that installed onboard MSC World Europa, can help fleet operators
comply with clean-ship environmental regulations while also
helping to reduce operating costs.
The induction technology that GE Power Conversion developed
about two decades ago was first used by the world's navies. Today,
it is used widely for a range of vessels which require power output
in the multi-megawatt classes for electric power and propulsion efficiency.
" For
delivery of long-term performance, in-board electric propulsion
technology is optimal for cruise vessels as it can deliver a
robust power source that balances energy efficiency and propulsion
reliability with a reduction in maintenance costs, " explained
Loic Thiebaut, merchant marine business leader at GE Power
Conversion. " GE has pioneered the use of both high-power induction
motors and PWM for marine operations and has demonstrated
a track record of applying this technology efficiently in the
powering of world-wide cruise vessels. "
" We value our long-standing relationship with MSC Cruises and
recently also expanded our contribution to the MSC fleet with
the fit of the fourth vessel in the Seaside series, Seascape, " he
noted. " It's just one of the 17 MSC cruise vessels sailing with
GE's electric propulsion technology. "
Fuel cell systems coming via collaboration with Nedstack
GE Power makes large-power induction motors up to 40 MW
The World Class fleet are no ordinary cruise ships; the LNG dualfuel
vessels are propelled by the most powerful cruise ship electrical
motors in operation - two 25 MW, 120-127.5 rpm induction
motors induction motors - which are fed by four press-pack IGBT
(insulated gate bipolar transistor) PWM MV7000 converters. The
systems from GE also include four propulsion transformers and
remote control for onboard propulsion, technology that can contribute
to improved propulsion reliability and lower maintenance
costs during the vessels' operating life cycle.
" Against the backdrop of a competitive environment, we are con8
