Charting a New Course with eWolf

Leading the Pack with eWolf

A zero-emissions design brought to life by Crowley in 3D

By the Numbers

In the first 10 years of its use, the eWolf—the first of
more sister tugboats under development by Crowley—
will reduce 178 tons of nitrogen oxide (NO x), 2.5 tons of
diesel particulate matter, and 3,100 metric tons of
carbon dioxide (CO2) versus a conventional tug.
