Hybrid Marine Propulsion Systems – propulsion systems coupling diesel engines with electric drive – have been around only for a few years but the industry is currently growing at a 12% rate y/y and is expected to grow at a 8% CAGR up to 2022 , compared with a 3% rate for standard fossil-fueled engines.
Though type-certification standards are long-established about single components – engines, generators and batteries, battery management systems – there are no standards about the hybrid systems as a whole and more specifically about performance prediction systems.
Published trials by engine and ship manufacturers claim significant results in terms of fuel saving and emissions reduction in actual installation on OSVs , tugs, ferries . Still there is no evidence of the methodology used to calculate the performances and to prove consistency in the results with different vessels.
Project outline and expected results
It is known that the performance of diesel engines at partial loads is different from the performance at full load. …. Continue reading from the original post on LinkedIn here >> https://www.linkedin.com/pulse/hybrid-marine-propulsion-project-assess-marco-bonvini.
