Bay Shipbuilding Launches Tank Barge For Hannah Marine
The tank barge Hannah 6301 was launched recently at Bay Shipbuilding Corporation, Sturgeon Bay, Wis. The launching was witnessed by a group of Hannah Marine Corporation personnel and customers and Bay Ship officials. The vessel was christened by Hannah's appointed sponsor for the occasion, Mrs. Georgianne Lamb, executive secretary to Donald C. Hannah, president of Hannah Marine.
At 407 by 60 by 21 feet, with a capacity of 63,000 barrels, the 6301 is currently the largest of Hannah's fleet of nine barges. It is expected to see light oil service on the Great Lakes.
This vessel, designed by naval architect George B. Drake Jr., is certified Full Ocean Loadline for Subchapter '0', Grade A and lower products, Type III hull. With 10 cargo tanks, she is doubleskinned. The cargo tanks are coated with a phenolic epoxy. Among the many features of the barge, it has three segregated piping systems with three Johnson deepwell cargo pumps rated at 3,500 barrels per hour each. The barge has four cargo crossheader locations, hose derricks, Beebe winches, and a nitrogen purge system. The ballast system consists of five inner bottom wing tanks, forward and aft rakes, with two ballast pumps at 500 gpm each. The barge is also equipped with a Bird-Johnson 350-hp bow thruster, a 30-kw generator, two 450-cfm diesel air compressors, and one 10-hp electric air compressor.
The 6301 features the Bludworth articulated linkage pushing system, is equipped to transit the St. Lawrence Seaway, and meets the height and width requirements for the Chicago River bridges.
