The following is the text of a news release from the U.S. Maritime Administration (MarAd):

(WASHINGTON) — The Maritime Administration has announced the availability of a report evaluating the design and construction of new battery components, as well as the risks and benefits of battery use in the power plant of a hybrid tugboat. The assessment, which was conducted after a battery-related fire aboard a hybrid tug, looks at the benefits and risks associated with the reinstallation of batteries as part of the vessel’s hybrid power system. 

The assessment showed that a refined design with explosion protection, structural separation from occupied spaces, specialized battery controls, and shutdown protocols improved the risk profile for the hybrid power system. The assessment also demonstrated that without the battery array, the hybrid system would not achieve the tug’s full performance requirements nor the emissions and fuel consumption reductions made possible by hybrid technology.

The report was developed through a partnership with Foss Maritime Co. with funding from MarAd’s Maritime Environmental and Technical Assistance (META) Program. MarAd’s META program is designed to assist maritime stakeholders in addressing key environmental issues facing the industry.
