GE Powering Electrification of Maritime Propulsion
Equipped with high torque-density advanced permanent magnet motors, GE Power's Seajet propulsion pods help marine vessels maneuver
through harsh ice flows and frozen seas
Designed with versatility and dependability in mind, an extensive
array of systems from GE Power are bringing propulsion electrification
to maritime fleets. Serving both naval and commercial vessels,
many incorporate cutting-edge magnetic technology to accomplish
their tasks and to replace hydraulic systems. Coming next, the company
is focusing on new electromagnetic launch systems for military
craft and new gas turbine solutions -- as well as fuel cell systems,
through a collaboration with Nedstack Fuel Cell Technology of Holland.
GE
Vernova's Power Conversion business has designed vessel
electrification technologies that are helping the world's leading navies
and coast guards to energize their missions with high levels
of power-sharing flexibity. Through integrated electrification, energy
management, automation and control, power in the ship's electric
grid can simultaneously supply high-energy mission systems and
electric propulsion. Energy-efficient architectures also serve as an
effective way to integrate new, cleaner, energy sources as they
emerge, and host digital technologies to implement more autonomous
systems.
Its SeaJet range of podded propulsion systems brings efficiency
and maneuverability to operation in harsh, sea ice conditions. Power
Conversion is now launching SeaJet power range from 1.5 MW to
4 MW, using low voltage (<1000 V) ideal for smaller ships.
With high steering capability, SeaJet provides very good transit and
bollard pull performance. Powered by the SeaPulse low voltage
DC drive system and a high torque-density Advanced Permanent
Magnet Motor (APMM), the pod eliminates the need for hydraulic

systems, thanks to the
integration of an electric
steering system with
electrical actuators and
intelligent control system,
enhanced cooling system,
Eco-sealing technology
and advanced bearing
technology in a compact
package. The system also
embeds digital asset performance
management
(APM) technology, helping
to enhance availability,
reliability and maintainability.
" There
is increasing investment
in polar exploration
and arctic routes for
shipping but also in polar
region protection, "
explains
Moises DelToro, marine leader for North America at Power
Conversion. " The first-generation pods produced by GE Vernova
have demonstrated their robustness across naval, merchant and
offshore applications for decades, and the new generation is gaining
traction with owners building Arctic tonnage that require rugged,
ice-class performance. SeaJet will play a key role in serving this
growing demand, including new applications such as expeditionary
passenger vessels. "
