Ocean Towing

Foss provides ocean towing to support the mobilization of materials to remote sites around the world. Operating in the harsh Alaska environment on a recent project, Foss towed prefabricated silo components for a major contractor working on the Ground Missile Defense project without incident. Additional information, capabilities and examples can be found on International Project Logistics and on Domestic Project Logistics.

Featured Projects

Foss is proud to serve our global community with specialized maritime services. From providing disaster relief efforts in the United States, Haiti and Puerto Rico and emergency rescue towing to most recently towing a decommissioned Navy vessel from the U.S. West Coast to Texas via the Panama Canal. During the initial months of the COVID-19 pandemic in 2020, Foss assisted the USNS Mercy ship into the Port of Los Angeles to serve as a backup hospital for the city of Los Angeles.

Our Fleet

Foss Maritime is dedicated to industry innovation and creative solutions. From introducing the first tugboat launches in Tacoma in the late 1800’s to diesel tugboats and developing the first Tractor tugs and one‐of‐a‐kind hybrid tugs. Foss has been focused on optimizing our fleet from the very beginning. We continue to build, design and add state-of-the-art vessels to our powerful fleet and most recently added three ASD-90 Tier 4 tugs which meet the EPA’s highest emissions standards.
