Electric Tunnel Thrusters

Home > Products > Tunnel Thrusters > Electric

Electric drive tunnel thrusters with fixed pitch propeller are available from 250 to 3,000 HP.  They are designed for variable speed electric motor input, either DC with SCR control systems or AC with variable frequency drives.  Most of them are used in dynamic positioning applications.  Thrusters can be supplied complete with electric motors and drives or they can be made to fit flange and shaft end of a customer supplied or shipyard supplied electric motor.  Many sizes are available.  Please contact our sales department for your application. Some models have ABS Type Approval.
