Most electric vs. diesel cost comparisons measure the price of retrofitting new technology into an old design. This session starts from a different premise: what happens when a vessel is built around distributed electrical architecture from the beginning? When done correctly, this approach produces a vessel that is cheaper to construct and operate than its diesel equivalent. 

To prove this finding, speakers will present validated build cost comparisons across four configurations of a 100-ton harbor assist tug: Tier 4 diesel, parallel hybrid, series hybrid, and fully electric. Learn what distributed architecture removes from a vessel, what it adds, and how it changes what’s possible at the design phase. 

Attendees will: 

• See build cost comparisons across four configurations and understand how those numbers are achieved
• Learn what distributed electrical architecture eliminates from a vessel, what it adds, and how that drives both cost and design advantages
• Evaluate ten-year ownership economics at real port duty cycles
• Understand how to evaluate distributed electric architecture as an option for your operation and choose between parallel and series hybrid configurations
