Crowley announced that it has expanded its harbor services capabilities through the acquisition of Main Line Inc., a vessel mooring company based in Seattle, effective January 1, 2025.

The addition of Main Line will provide Crowley’s customers calling on the ports of Seattle and Tacoma, Washington with a comprehensive solution for their vessel mooring and ship assist needs.

Main Line is a longtime provider of vessel mooring services in the Pacific Northwest for ship operators who value safe and dependable mooring service. Main Line staff members are transitioning to Crowley as part of the asset purchase agreement. Terms were not disclosed.

“For decades, our customers have put their trust in Crowley to ensure their vessels arrive and depart ports safety and reliably,” said James C. Fowler, senior vice president and general manager, Crowley Shipping. “The addition of vessel mooring to our harbor services product offering ensures the highest levels of coordination between the critical services of vessel mooring and ship assist. As a result, Crowley customers can have even more confidence their vessels will be docked and sailed without delay or incident.”

A provider for more than a century, Crowley has deployed technologically advanced and environmentally friendly tugboats, combining capability and cleaner emissions to support timely harbor operations.

Crowley is a privately held, U.S.- owned and -operated maritime, energy and logistics solutions company serving commercial and government sectors with $3.5 billion in annual revenues, over 170 vessels mostly in the Jones Act fleet and approximately 7,000 employees around the world – employing more U.S. mariners than any other company.
