San Giovanni in Marignano, Italy (2nd November 2021) – Torqeedo and Italdraghe today announced the joint development of an outboard, retractable electric propulsion system for commercial and working vessels in inland and urban waterways.

The system combines Italdraghe’s proven and extensively field-tested steerable azimuth thrusters and Torqeedo’s Deep Blue high-voltage electric power system. It is designed to provide emission-free power and directional thrust ideal for manoeuvring on environmentally sensitive waterways.

Italdraghe’s azimuth thrusters have been integrated with Torqeedo’s Deep Blue systems in order to develop two types of electrical rudder propeller, one delivering a continuous power of 50 kW and a maximum power of 65 kW and the other delivering a continuous power of 100 kW with a maximum power of 120 kW. The propellers can rotate up to 360° degrees, and the drive units have a 600 mm depth regulation for operation in shallow water and can be tilted up to 60° degrees for maintenance without need for deinstallation from the boat.

Engineer Massimo Semprini, Italdraghe’s technical and sales director, said, “Our integrated electric solution is designed to make the investment to convert existing fleets to electricity even more economically and ecologically beneficial. We will collaborate closely with Torqeedo’s application engineers to design and install the ideal system for each application. Most commercial fleets in European cities are powered by decades-old marine diesel engines. Their CO2 emissions are not in line with the international goals to reduce global warming, and human health is also at risk. Electrification of commercial fleets in inner-city waterways can be accomplished easily and cost effectively, since vessel speeds are limited – resulting in lower battery discharge rates – and they typically operate only 8 to 14 hours per day, leaving plenty of time for overnight charging.”

The new electric propulsion package will be on display on Stand 4214 at the 2021 Europort exhibition in Rotterdam 2-5 November.
