Design of a Low Emissions Harbor Tug

January 1, 2008

Crowley Maritime Corporation has designed a next generation solution for a very low emissions ship assist tug for service in Los Angeles and Long Beach (LA/LB) harbors. The tug will substantially reduce both US Environmental Protection Agency (US EPA) regulated emissions and currently unregulated greenhouse gas emissions over conventionally powered tugs in similar service. The vessel will be more powerful than any tugs now operating in the harbor, positioning it well for current and future service. The tug will also set new standards with respect to other shipboard emissions. Finally, the design considers issues of crew habitability such as safety, noise, and comfort.
