application for the Coast Guard. Eastern Shipbuilding Group is
the prime contractor and builder of the next-generation offshore
patrol cutters.
DRS will provide its high-performance, permanent magnet motorbased
Auxiliary Propulsion System. The integrated hybrid electric
drive system has been optimized to meet the Coast Guard's
operational tempo and provides capability for the ship to operate
much more efficiently at slower speeds, increases mission
duration capability, reduces emissions, and provides emergency
take-home capability in the event of a failure of the main propulsion
diesel engines. When coupled to the main propulsion gearbox,
the system allows the ship to operate quietly and efficiently
during loitering operations while providing superior fuel economy
for increased on-station operations and capability.
Already used in multiple oil & gas, marine and transport applications,
the system includes two of the most power-dense
permanent magnet motors on the market providing significant
advantages in size, weight, efficiency and performance over conventional
electric induction motors and produce more torque from
the same amount of supplied current. Their smaller footprint
allows greater flexibility in engine room design and increased
cargo space, and their simpler more rugged construction results
in proven reliability and durability, notes the company.
Maximizing use of the electric drive increases the platform's
green credentials and reduces operational time on the main propulsion
engines, providing additional multiple benefits. Because
electric motors are virtually maintenance free, life cycle costs
over the planned 40-year vessel life are minimized by reducing
maintenance hours needed on the engines. Using propulsion
diesel engines at slow speeds adds significant wear and tear on
the engines and increases the potential for coking/wet stacking.
By adding the electric auxiliary propulsion system, the Coast
Guard expects to have a built-in advantage of reducing not only
fuel and maintenance requirements, but total lifecycle costs and
increased safety for the fleet. The main engine overhaul cycle,
typically planned at 15 years, can be extended to 25 years.
