Project Summary

A feasibility study to define operational parameters and design characteristics for a unique gearbox that delivers electric propulsion in an efficient manner for use in large vessels not currently capable of transferring to clean powertrains.

Project Achievements

Activities • Project Management and Exploitation • Desk Level Definition of Design Parameters • Desk Level Initial Gearbox Assembly Drawings • Fabricate Gearbox with Ecomar Motors – This exceeded the planned project activities

Conclusions

It is viable to produce a multi motor gearbox for clean marine vessels. Provides evidence that advance control systems are required to operate successfully. Synchronisations of motors is essential and that advanced techniques such as a field weakening need to be incorporated into electrical operating design. This project opened new technical opportunities in advanced clean electric propulsion.

Next Steps

Archive successful completed system hardware bench tests. Design and implement a more advanced control system. Multipower trains for commercial workboats up to 1MW which means we can pursue a much wider market for bigger vessels than our current clean propulsion systems can achieve.
