Design and specification of marine transmissions for the hybrid/electric future
A marine transmission serves a critical role within the context of the overall propulsion system, particularly for electric & hybrid vessels. There are multiple possible approaches for hybrid/electric propulsion, including transmissions with PTI configurations, parallel hybrid arrangements with specialized power-splitting transmissions, and fully electric drivelines with transmissions featuring external lubrication systems. Transmissions must be carefully designed, selected and configured to match the needs of each application, including the desired operational modes (boost, motor generator, electric, etc).
