Electric Retractable Thrusters

Thrustmaster electric retractable thrusters are fixed pitch
propeller thru-hull azimuth thrusters capable of retracting completely
into the hull. They are configured for vertical variable
speed electric motor input. Sizes range from 250 to 10,750
HP (185kW to 8.0MW) with a wide selection of reduction ratios
and propeller/nozzle diameters to suit the application requirements.
They are normally supplied complete with electric motors and
variable frequency drives, but they can also be made to fit flange
and shaft end of a customer supplied or shipyard supplied electric
motor. The motor travels up and down with the thruster,
so the drive line is never disconnected. They can be provided
with open propeller or with nozzle. They are also available
as combination thrusters, functioning as tunnel
thruster in the retracted position and freely azimuthing
in the lowered position. Compact units are available for
vessels with limited hull depth. A hull fairing piece is
normally attached to the bottom of the thruster to reduce drag
when the thruster is stowed.

Notice, all drawings are typical only, and can be adjusted
to meet your application needs. We can vary the propeller size
and leg length to best meet the vessel configuration, user preference
or speed versus thrust requirements.

details for your specific application.
