Pulling-e Propulsion® has been developed using the decades-old tradition of designing large ships with an alternating operation profile. Such vessel types, like cruise and icebreakers, have been using the principles of optimisation design since the 1980s, leading to the wide use of pulling types of propeller. Our product portfolio focuses on solutions open water for small and medium size shipping, up to 600kW per torpedo (usually one torpedo per shaft line, but variations can be applied).
Our Pulling-e Propulsion® drastically improves the overall efficiency, which means less installed power compared to traditional components and design. Radical results are also needed to reduce the overall weight and space requirement. Alternative fuels, such as methanol, are not as compact as conventional fuels, like diesel. The rest of the system must be reduced to keep the overall system size and weight reasonable and practical.
Pulling-e Propulsion® is an electric podded propulsion that has been revised and the risks minimised. We want to secure the quality of the components and manufacturing, by choosing always the best provider for the job. This means that reliability in proven and the spare part availability is global. We want to be sure that if we sell products to every corner of the world, they can also be used and maintained in every corner of the world, by local professionals. No need to send out specialists from the other side of the world. Therefore, we aim for the simple and for something that can be maintained by the operator.
The main innovations of the Pulling-e Propulsion®
- A new innovative and very light concept to rotate the propeller firmly
- 360° thrust without heavy steering gears, swivels or slip rings
- Market-high propeller design efficiency (eta 0.83-0.89)
- Simple and reliable design, which drastically reduces the space inside the hull
- Hull design options to improve overall resistance massively, and to add buoyancy.
- Refit installation options, avoiding major overhaul of the hull.

For ship deliveries utilising alternative fuels, such as Green Methanol or similar, the gain of space and less weight is mandatory for long-distance operation. The propulsion system weight (together with the electrical system) is a crucial reduction element for reaching the practical and competitive outcome.
