Fleetzero’s U.S. manufactured lithium iron phosphate marine battery system receives Product Design Assessment for marine applications
ABS has issued a Product Design Assessment (PDA) to Fleetzero for its Leviathan Battery Energy Storage System (BESS), marking what the companies describe as the first lithium iron phosphate (LFP) marine battery system manufactured in the United States to receive classification approval.
The PDA reflects ABS review of the Leviathan system for marine application and supports its use in future projects requiring class-verified battery technology. Built on LFP chemistry, the system operates at up to 1,000 VDC, supports a depth of discharge from 2 percent to 98 percent and carries an IP67 rating. The Leviathan’s modular, containerized design allows the system to be specified, deployed and replaced across a range of vessel types and applications.
“As the industry works through the practical challenges of electrification, class-verified battery technology plays an important role in building confidence among owners and integrators,” said Gareth Burton, ABS Senior Vice President, Global Engineering. “The PDA for the Leviathan system reflects the rigorous technical work required to bring a new marine battery solution to market safely.”
The first commercial deployment of the Fleetzero Leviathan system will be on the water later this year. The first project will use 10 MWh of Leviathan battery capacity as part of a vessel’s broader conversion to hybrid-electric propulsion.
“This approval is the result of years of disciplined engineering and close collaboration with ABS,” said Steven Henderson, CEO and Co-Founder of Fleetzero. “The maritime industry needs proven, class-approved energy storage that is built on a safe, scalable chemistry. The Leviathan delivers exactly that, and we are putting it to work immediately.”
