Azipod is the registered brand name of the ABB Group for their azimuth thruster. Originally developed in Finland jointly by Kvaerner Masa-Yards dockyards and ABB, these are marine propulsion units consisting of electrically driven propellers mounted on a steerable pod. The pod's propeller usually faces forward, as in this puller (or tractor) configuration, the propeller is more efficient. |
