Crowley Maritime has entered into a bareboat charter agreement with Brusco Tug and Barge for a tractor tug that will serve Pacific Northwest and California ports with ship assist and harbour escort work.

The vessel will be renamed Hercules and it was constructed by Diversified Marine in Portland, Oregon. The engines drive two Rolls-Royce azimuth stern drive (ASD) thrusters and provide 81 tons (73.5 tonnes) of bollard pull.

"The technology on the Hercules will ensure our customers get in and out of port efficiently to meet the demands of their supply chains, whether their vessel is a large tanker, a modern container ship, or other craft," said Porter Sesnon, general manager of Crowley’s ship assist and escort services.
