On 14 April 2022 Crowley took delivery of Athena, its fourth and most powerful Tier IV ship assist and harbour escort tugboat.

The 77ft Athena provides the agility of its compact size without the sacrifice of power, offering the most bollard pull for a tug under 80ft in the market.

The vessel is powered by a pair of Caterpillar Marine 3516 Tier IV-compliant engines, resulting in lower greenhouse gas emissions while achieving a power output of nearly 6,800hp and 96 tons of bollard pull.

Serving the Pacific Northwest out of Puget Sound, Washington, Athena, built by Diversified Marine Inc. and chartered from Brusco Tug & Barge, complies with US EPA Tier IV pollution control technology criteria.

The vessel is outfitted with remote monitoring for increased vessel efficiency and data interchange.
