Propulsion pods may be the greatest thing that ever happened to cruise ships. Or maybe the worst, when they don’t work, which is far too often. A propulsion pod is an electric motor which drives a propeller mounted on a rotating “pod” which extends out from the bottom of the ship. Because they can be made to rotate 360 degrees, the pod replaces the traditional rudder and stern thrusters and does away with the need for long propeller shaft runs. They are more fuel efficient than conventionally mounted propellers, by around 6-9%, which given today’s fuel costs is significant. Two manufacturers dominate pod propulsion — Rolls Royce who manufactures the “Mermaid pod” and ABB which manufactures the “Azipod.”
