Starting with cruise ships and LNG carriers, electric propulsion systems are becoming popular as system designers seek to enhance operational flexibility, reduce noise emissions and closely match engine power produced to engine power demanded. Like all innovations, these systems present challenges in practical operation. This article is based on a paper presented at the recent Torsional Vibration Symposium,

1 Motivation

Special marine propulsion applications demand efficient manoeuvrability under extreme conditions. As such, operation at speeds requiring lower propeller rotations is essential for effective control. In addition, vibration resonance and radiated noise from the propulsion shafting system must be kept to a minimum, as far as possible. A self excited torsional vibration phenomenon occurring at the lower speed range of a special purpose vessel has been investigated in an electric propulsion shafting system consisting of a motor, a coupling and a propeller, and supported by a...
