For 128 years, Foss has been dedicated to developing the best transportation solutions and, when challenges arise, solving them proactively in close partnership with our customers.

Foss was the first operator of tractor tugs in the United States and is now recognized internationally as a leader in tanker escort and assist services. Our ability to expand, contract, replace and build equipment as opportunities and circumstances present themselves is unmatched.

Since the introduction of tractor tug technology Foss has continuously led the industry in technological innovations. Today we operate the largest and most diverse fleet of tractor tugs in the United States and a modern and capable fleet in the Columbia River, from our 8,000 horsepower Voith Schneider Enhanced Tractors to our newest tractors, the 5,080 horsepower Dolphin-Class Azimuthing Stern Drive (ASD) Tractors, including the Green Assist™ Dolphin, the world’s first hybrid tug.

Foss continues to drive industry innovation with cutting-edge engineering and ship construction. Our state-of-the art ASD Z-Drive and Voith Schneider Propulsion (VSP) cycloidal tractor tugs can control the world’s largest tankers and freighters.

As innovators of tractor tug technology and training, Foss actively engages in vessel research, design and operation as well as in the development of escort/assist procedures and pilot/tug training. In addition to meeting our customers’ needs, Foss also supports the U.S. Coast Guard, the maritime industry and port operations, including the Panama Canal Authority, Sullom Voe Terminal, the Louisiana Offshore Oil Port (LOOP) and the Hibernia Oil Project.
