1 Icebreakers have to have powerful engines and be of a robust construction
take up minimal space: This two-stage
turbocharging system is 20 percent more
compact than conventional two-stage
turbocharging solutions. Space saving
is especially critical in an icebreaker as
the extremely strong hull construction
of the vessel leaves less internal space
than would be available on an equivalent,
regular ship.
The Power2 800-M’s extractable cartridge
enables service to be completed in just
two steps instead of the previous six,
making maintenance easy and reducing
downtime and service costs.
On the icebreaker’s engine, the Power2
800-M will enhance fuel efficiency and flexibility
of operations. With up to 60 percent
less NOx emissions, the Power2 800-M
also substantially cuts discharges to the
atmosphere – an important aspect for
operation in the pure Arctic environment.
The Power2 800-M responds to the need
for new marine engine technology to offer
consistency of performance across conventional
and newer marine fuel options.
This application will demonstrate the advances
in efficiency and power density
now available for four-stroke engines
that operate over a wide range of load
profiles and that face added demands
from various bodies who regulate emissions.
Once the icebreaker is constructed,
commissioned and operating in iced-up
port waters, the capabilities of the Power2
800-M will prove to be invaluable in providing
the power to keep waters ice-free
for shipping.
Power2 800-M is
the most compact
turbocharger of its
kind.
With a low-pressure and high-pressure
stage, the Power2 800-M provides
higher air pressure ratios – up to 12 from
eight in the previous generation. A single-stage
turbocharger can operate at
around 65 to 70 percent efficiency;
Power2 800-M exceeds 75 percent efficiency
and is the only system currently
available across the large-engine industry
with this capability.
