Marine Propulsion

Solution Overview

Flexible Propulsion Architecture Built Around Vessel Requirements

Advances in variable speed drive technology have made electric propulsion a proven choice across cruise ships, offshore construction and drilling vessels, icebreakers, offshore support vessels and LNG carriers.

MJR engineers AC and DC propulsion architectures around vessel duty, redundancy, power distribution and integration requirements for diesel-electric, hybrid and fully electric applications.

Operational Benefits

Benefits of Electric Propulsion
