Learn About Marine Technology
Verified Marine Technologies for SmartWay and Clean Diesel
- Repowering (i.e., replacing) or upgrading engines; and
- Installing retrofit emission control technologies.
- Fuel consumption;
- Particulate matter (PM);
- Nitrogen oxides (NOx);
- Hydrocarbons (HC);
- Carbon monoxide (CO);
- Carbon dioxide (CO2); and
- Other air pollutants.
Verification for Marine Technologies
Technologies to save fuel and reduce emissions for marine engines can be verified by EPA. Due to the unique nature and custom design of these technologies, EPA will review and approve them on a case by case basis.

Marine Shore Power Connection Systems
Shore power systems allow maritime vessels to “plug into” land-based electrical power while at dock instead of using on-board diesel auxiliary engines. Shore power systems must enable a compatible vessel’s main and auxiliary engines to remain off while the vessel is at berth. Systems typically include various components such as cables, cable management systems, shore power coupler systems, distribution control systems, and power distribution.
Due to the unique nature and custom design of marine shore power connection systems, specific products and vendors are not listed. Marine shore power systems must comply with international shore power design standards (ISO/IEC/IEEE 80005-1-2012 High Voltage Shore Connection Systems or the IEC/PAS 80005-3:2014 Low Voltage Shore Connection Systems) and should be supplied with power sourced from the local utility grid.
Quantifying Emission Reductions for State Implementation Plans
Using these technologies may reduce emissions of NOx, HC, CO, PM and possibly SOx and CO2. For state and local air quality planners and transportation officials, these emission reductions can be used in air quality plans such as state implementation plans (SIPs), as well as transportation and general conformity.
