Abstract

A hybrid electrical and mechanical ship propulsion and electric power system, includes a first mechanical power plant configured to drive a first propeller via a first shaft. There is a second electrical power plant configured to drive a second propeller via a second shaft. The second electrical power plant includes HTS generators and a high temperature superconductor (HTS) motor interconnected to the second shaft. There is a first electrical network to which the HTS motor is connected in order to energize the HTS motor to drive the second propeller via the second shaft.
