Royal Netherlands Navy new combat support ship
GE leveraged proven technologies to deliver a low risk, robust
full-electric propulsion system which is ideally suited to long
range operations above the Arctic Circle, it said. The Integrated
Full Electrical Power and Propulsion System (IFEP) includes
the induction propulsion motors, variable frequency drive
converters for propulsion and bow thrusters, engine generators,
medium voltage switchboards, distribution and propulsion
transformers, bow thruster motor, commissioning, and sea trials
support.
" GE Power Conversion's dedicated AOPS team developed
a close working relationship with the customer, Irving Shipbuilding
Inc., maintaining an open line of communication that
was instrumental in meeting this key milestone for the Royal
Canadian Navy. " , said Ron Krivan, AOPS Program Manager for
GE Power Conversion. " Our team will carry the same dynamics
with Irving Shipbuilding moving forward in support of construction
of AOPS 7 and 8 for the Canadian Coast Guard. "
For the full-electric propulsion system, GE leveraged its proven
technologies, building on recent experience in providing power
and propulsion solutions for naval ice class vessels for South
Africa and Chile, as well as other commercial vessels.
The drive train for each of the two propulsion shafts includes
GE's MV7000 variable frequency drive which is used in many
vessel types around the world as well as in numerous industrial
applications. Each shaft is directly powered by a slow speed
induction motor with optimized design for ice operations, including
an ability to deliver high intermittent over-torque at zero and
low RPM should the propellers encounter heavy ice loads. This

feature makes the AOPS propulsion solution highly suitable
for a variety of other ice class vessels that could operate in the
Arctic and Antarctic.
With 9MW of installed nominal power propulsion power, the
IFEP system comprises all shipboard electrical power generation
and propulsion. Offering high over-torque, the electric
propulsion system eliminates the need for propulsion reduction
gears, an important factor for ships operating in heavy, multiyear
ice conditions.
GE's Power Conversion business reported that it has signed a
contract with Damen Schelde Naval Shipbuilding to deliver an
energy management and electric propulsion package intended
for a new combat support ship, depicted above, for the Royal
Netherlands Navy.
According to GE, its technology was selected for its low noise
signature, high level of reliability and commonality with the Joint
Support Ship (HNLMS Karel Doorman). One of the customer's
key concerns is underwater radiated noise, meaning strict noise
and vibration levels are imposed on the propulsion systems.
Pulse Width Modulation voltage source inverters feed robust,
high-torque density induction motors, allowing high-performance
through the modern and optimized propulsion system.
Delivery of the vessel is planned for June 2024.
