The U.S. Maritime Administration (MARAD) awarded a $200,000 Cooperative Agreement under the Air Emissions and Energy Initiative (CFDA 20.817) program to Noise Control Engineering, LLC to compare the underwater noise generated by a conventional diesel-powered ferry and a new battery-electric ferry. The key activities and deliverables include:
- Measure the underwater radiated noise (URN) of the two ferries under equivalent operating conditions to allow direct comparisons.
- Analyze the collected data against commercial noise standards to identify potential noise reductions achievable through battery-electric propulsion systems.
- Provide a detailed report of all findings to MARAD and Noise Control Engineering, LLC to inform vessel owners and operators of opportunities to reduce underwater noise through engine modifications or alternative power sources.
The award period runs from February 19, 2024 to September 19, 2025. This project builds upon previous MARAD-funded underwater noise studies conducted by Noise Control Engineering, a subsidiary of the engineering firm Glosten, Inc.
