Products & Services


Deck Cargo Barges

Deceptive in their simplicity, our deck cargo barges are built to meet a variety of cargo needs and specialized operating environments. From heavy break bulk equipment, containers, vehicles or railcars, these barges are extremely versatile. We have constructed heavy lift barges up to 120 feet wide and up to 6,000 lb/sq ft uniform deck loading; we can go even wider to capitalize on the new greater Panama Canal width. Our innovative construction techniques have been proven to save the operators lightship weight and increase their cargo carrying capacity.

Dump Scows

Dump scows are unique and very important vessels that carry shipments such as sand, soil, waste, and dredged material.  The differentiating design feature of a dump scow is the ability to release contents through the underside of the barge by hinging the barge open to dump the cargo.  Gunderson Marine is the recognized industry leader in the construction of these vessels.  We have proven construction methods to ensure that the large hinges are perfectly aligned and that the integrity of the seal formed by the two watertight hulls is maintained.

Tank Barges

Tank barges are used to transport a variety of bulk liquids. Our double hull tank barge designs are built for optimum quality and safety.  We bring a significant amount of experience to the quality design and construction of double hull tank barges at our historic Gunderson facility in Portland, OR, where each barge is tailored to a specific commodity.

Articulated Tug and Barge Units (ATB's)

Gunderson Marine is a premier builder of articulated tug and barges (ATB’s). Articulated barges are an attractive alternative to towed barges and self-propelled tankers due to their improved reliability, lower capital and operating costs, and increased operating efficiency. We have experience constructing several different ATB connection systems and utilize specialized welding sequence methods to ensure that the barge ladder is perfectly aligned to accept the pins from the tug.

Hopper Barges

Gunderson Marine offers a variety of hopper barges at our historic marine manufacturing facility in Portland, Oregon.  Hopper barges are used in the transportation of bulk commodities such as coal, limestone, grain, sugar, and other aggregates.

Rail Car Barges

We offer top quality rail barges that draw on our storied experience in both the marine and rail industries. These barges have rail tracks on deck and carry trains to destinations where they would otherwise have difficulty reaching. 

Inland River Barges

In addition to our extensive ocean barge offerings, we also build a variety of inland barges for river transportation.  Our historic Gunderson plant in Portland, OR, is located on the Willamette River which connects directly to the Columbia River, a key waterborne transportation route for the Pacific Northwest.
