The podded propulsion system is the largest step forward as propulsion unit in the recent years. The concept is not yet fully developed for all market and power applications, and there will be a continuous development to be seen.
This may have significant impact on vessel design and allow for total new ship concepts for many areas.
In the CRP concept (Contra Rotating Pod), the podded propulsion is combined with a traditional shaft line driven propeller.
The Pod is azimuthing and controlled with a variable speed electrical motor, and the shaft line propeller can be either speed controlled with electrical motor, or a conventional pitch controlled direct diesel driven propeller.
The CRP concept has shown to give a large improvement in propulsion efficiency, as well as increased redundancy and propulsion power for a several ship types.
