Crowley Maritime Corp. announced today that it has taken delivery of Athena, its fourth and most powerful Tier 4 ship assist and harbor escort tug.

The 77' Athena provides the agility of its compact size without the sacrifice of power, offering the most bollard pull for a tug under 80' in the market, Crowley said. The vessel operates on a pair of 3,400-hp Caterpillar Marine 3516 Tier 4-compliant engines. This results in lower greenhouse gas emissions while achieving a power output of nearly 6,800 hp and 96 tons of bollard pull.

“We are proud to add another powerful vessel to our Tier 4 fleet,” Paul Manzi, vice president, Crowley Shipping, said in a statement. “Joining sister Tier 4 tugs Hercules and Apollo as well as our tug Valor, Athena further exemplifies Crowley’s commitment to sustainable performance for customers, advancing our progress to reduced emissions and a smaller carbon footprint.”

Serving the Pacific Northwest out of Puget Sound, Wash., Athena, built by Diversified Marine Inc., Portland, Ore., and chartered from Brusco Tug & Barge, Longview, Wash., complies with EPA Tier 4 pollution control technology criteria. The vessel is outfitted with remote monitoring for increased vessel efficiency and data interchange.

“We are pleased to have built another record setting tug for Crowley’s fleet. Athena is going to be a head turner in the Puget Sound,” Frank Manning, vice president, business development and operations, Diversified Marine, said in a statement.
