THE PROPULSION PACKAGE “Our engines maintain world class fuel ef? ciency while meeting the latest EPA

Tier 4 emissions regulations, which reduces engine

NOx emissions by 76% over previous engine models, without the use of costly aftertreatment systems.” – Tammy Gromacki,

She said Wabtec is working with MarAd, Tote, and the mari- time academies to provide a practical and ef? cient training pro- gram, including online and hands-on Wabtec Engine University

Looking at the propulsion system wholistically, Mankevich said “as with any ship, there’s always going to be the need for maintenance and upgrades. But with the electric drives, the long- term maintenance is altered in part because the biggest antiquity item will be the computer chips.” Another focal point for train- ing is safe operation of the onboard electrical system, ensuring the system is de-powered and access per plan.
