Rolls-Royce have developed a range of robust integrated electric propulsion system solutions that can be optimised for different operational modes on a wide range of vessels, saving fuel and reducing emissions.
An AFE drive is installed between the shaft-generator and the switchboard. This provides additional power when used with the main engine and provides full variable speed electric propulsion when the main engine is stopped, for slow speed/standby modes or as an emergency/take-me-home system.
To update to the HSG concept, requires a special motor and switchboard.
