Harley Marine Eco-Tug
Harley Marine Services, Inc. is reducing greenhouse gases, NOx, particulates, and diesel borne air toxics by converting existing harbor tugs to eco-tugs using ultra low emissions technology.
Working together with the Port of Los Angeles and Port of Long Beach to secure funding through their Technology Advancement Program, the M/V Maverick, a Millennium Maritime, Inc. harbor tug, will be the first tug of the Harley Marine fleet to undertake this “green” clean air retrofit technology.
The project involves conversion of existing Port and Starboard engines from mechanical to electronic configuration. The electronic upgrade is expected to achieve Tier II emission limits, which are the limits imposed for new marine engines. Additionally, the fact that harbor tugs spend almost 70% of their time at very low load operation, the main engines will be shut down and the power needed during this low load operation is going to be provided by a new smaller, more fuel efficient center engine added to the vessel that also meets Tier II emission limits.
