EBDG Announces Design of Harbor Power & Charging Barge

Naval architecture firm Elliott Bay Design Group (EBDG) announced at the International Workboat Show in New Orleans, Louisiana that it has designed a harbor power and charging barge.

The firm said the design gives ports and harbors a “cost-conscious and high-performing option to minimize emissions from large vessels both pier side and at anchor.”

With 7 megawatts (MW) of continuous power produced by methanol, the floating mobile platform is capable of “cold ironing even the most demanding vessels” at the pier and at anchor for up to two weeks before refueling.

According to EBDG, the vessel is equipped with a Wartsila W32M Tier IV methanol generator for cold ironing and an e1 Marine's M30 hydrogen reformer technology coupled with PowerCell's PS-185 Fuel Cell system for fast charging.

With the said combination of technologies, the designed vessel offers “exhaust emission reductions of 70%+ compared with conventional diesel at equivalent power.” The company also mentioned that zero full cycle emission is also attainable with an optional Wartsila carbon capture system and certified green methanol fuel.

Moreover, the vessel boasts double duty as an “in field” DC charging station for electric harbor tugs and other small service vessels.

“An independent ultra-low emission and nearly silent 1 megawatt system with 10 megawatt-hours (MWh) of reserve capacity continuously replenishes its reserve to provide fast charging capacity on-demand directly in the operating field of the vessels it serves,” the firm shared.

Furthermore, the platform does not exceed 225' in length. Additionally, it has a double hull protection for its methanol storage tanks, a Lloyd's Register classification of T1(b), and a Marpol 21.1.2 compliance, further optimizing its safety and environmental benefit.
