NABRICO Delivers Two Asphalt Barges To National Marine Service

Two 297-foot double-skin rake tank barges specifically designed for asphalt service by Nashville Bridge Company (NABRICO) have been delivered to National Marine Service, Inc. of St. Louis.

Each barge has a total capacity of approximately 29,000 barrels or 1,218,000 gallons.

For asphalt service, a barge must be heated at a constant temperature in order to keep the asphalt fluid. This heat is supplied by a volcanic heater and is transmitted by way of heating oil through a hot oil piping system.

The asphalt is unloaded by way of a Sier Bath pump at a rate of 2,800 gallons per minute. The total off-loading time is approximately 71/2 hours for each barge.

The barges are certified by the United States Coast Guard for the carriage of Grade "A" or lower products. They are provided with American Bureau of Shipping c l a s s i f i c a t i o n A-l Tank Barge, River Service and loadline for unmanned voyages between Chicago and Michigan City, Ind., and between Carrabelle, Fla., and St. Marks, Fla.

NABRICO is a wholly owned subsidiary of The American Ship Building Company, Tampa, Fla.

Headquartered in Nashville, NABRICO has been in the marine field for more than 60 years and is primarily concerned with the design, engineering, and construction of grain and coal barges, deck barges, liquid tank barges, cement barges, drydocks and towboats.

NABRICO is a major supplier to the entire marine industry of marine deck hardware. The company, which has plants in N a s h v i l l e and Ashland City, Tenn., pioneered the design and building of much of the modern equipment used on rivers today.
