The hybrid technology used to develop Foss’ Hybrid Tug is environmentally responsible—without sacrificing horse power or maneuverability. With its efficient combination of batteries, generators and main engines, the Hybrid Tug is both powerful and green.

Reducing Emissions. Improving Air Quality.

The Hybrid Tug is expected to significantly reduce emissions compared with the operating duty cycle of the conventional Dolphin tugs in San Pedro Harbor, including a reduction in nitrogen oxide, particulate emissions, sulfur dioxide and carbon emissions. This exceeds the EPA’s Tier 2 emissions requirement for marine engines. This tug design was awarded the EPA’s Clean Air Excellence Award for Clean Air Technology in 2008.

Along with less pollution, the hybrid offers improved fuel economy and lower maintenance costs. It is also quieter than its Dolphin sister tugs, when operating on batteries that can be recharged using shore power.

Hybrid Conversions

The flexible hybrid technology can be used to convert existing tugs of all types to hybrid vessels with lower emissions, improved fuel economy and lower maintenance costs. The Foss Engineering team can convert your standard tug to a hybrid tug, accommodating many tug designs and propulsion systems.

Why go hybrid?

• The Hybrid Tug reduces nitrogen oxide, particulate emissions, sulfur dioxide, and carbon emissions without sacrificing power or maneuverability.
• The Hybrid Tug’s extreme noise reduction improves the quality of life on the vessel, on shore, and under water.
• The technology used for the Hybrid Tug is extremely flexible, allowing it to be used to convert existing tugs of all types to hybrid.
• The Hybrid Tug improves fuel economy by reducing idling and increasing engine efficiency.
• Dozens of possible equipment configurations means the Foss Hybrid delivers the power you need when you need it.
