Generalidades -‐ Clasificación:
² Barcaza (Barge) u Hopper Barges
• Most versatile • Least costly • Most numerous • Double-skinned, open top with inner shell with welded steel construction forming a long
hopper or cargo hold ü Open Hoppers
• Carries commodities that need no protection from elements • coal, sand and gravel, crushed rock, limestone, logs, lumber
ü Covered Dry Cargo Barges • Carries commodities that need protection from elements
• grains, soybeans, paper products, cement, aluminum products, building materials, rubber, salt, sugar, and other products
u Tank Barges • Used for transportation of liquid commodities
bulk chemicals, acids, compressed gas, fertilizer, petroleum u Deck Barges
• Simple box hull, generally with a heavy-plated, well-supported deck • Carries cargo that needs to be tied down
• machines, vehicles, heavy equipment, logs, etc.

Generalidades -‐ Clasificación:
² Barcaza (Barge) u Inland waterways barges are very efficient
• One barge can carry up to five times its own weight • Capacity of jumbo barge (195 ft x 35ft) is 1500 tons (15 times greater than a rail car
and 60 times greater than one trailer truck • Average river tow is 15 barges tied together
u Barge sizes vary
• Jumbo dry cargo barges (open and covered) are 195 feet long and 35 feet wide with a loaded hull depth of 12 feet
• Jumbo barges are most common barge operating today • Barges operating on smaller rivers have loaded draft of less than 9 feet • Cost of construction is approximately $225,000 • Size is usually determined by the size of the most common locks (110 ft x 600 ft or 1200ft) • Other lengths are 175 ft x 35 ft with a capacity of 1000 tons and 290 ft x 35 ft with a capacity of
3000 tons • Tanker barges come in various sizes, but the most popular are 195 ft x 35 ft
• Built to double-hulled standards today, although some single hulls exist • Capacity of 10,000 barrels
• Some tank barges are 297 feet long and 54 ft wide • Capacity of 30,000 barrels • Construction cost is approximately $750,000 • Usually operated in tows of no more than three or four barges together
