Bollinger to build asphalt barges

Bollinger Shipyards, Inc., Lockport, La., has signed a contract to design and build five 297.5 foot, 30,000 barrel (BBL), double hull, hot asphalt tank barges for Horizon Maritime LLC, Houston. They are being built at Bollinger's Marine Fabricators (BMF), Amelia, La. Deliveries are planned for the first and second quarter 2005.

Lynn Falgout VP of BMF said, "These new barges will be similar to, but not identical to other hot oil barges we built for another customer. They will be built at BMF as we have increased production capacities there for both inland and offshore tank barges, as well as large offshore deck barges and boats."

Overall, each of the four raked and one boxed barges will be 297.5 feet long with a 54-foot beam and 13 foot depth at the sides, with trunks of 3.5 feet.

As the cargoes must flow in and out of the tanks at high temperatures, each barge will be equipped with a 6 million BTU Hopkins Volcanic high efficiency model HF602 heater to maintain the ability to load, heat and discharge liquid cargo.

The hot cargo from each of the barge's six tanks can be loaded and unloaded from either side. Pump One will be a three stage deepwell type Byron Jackson 12-inch model LS16GH and Pump Two will be an IMO model 4131C-800JD, deepwell screw pump. Owner furnished 530 H.P. Tier II John Deere diesel engines will power the pumps on each barge. Each pump will be capable of discharging any of the cargo tanks.

The barges are being designed and built in accordance with current American Bureau of Shipping (ABS) Rules for Building and Classing Steel Vessels for Service on Rivers and Intracoastal Waterways. They will be certified by the U. S. Coast Guard for rivers, lakes, bays and sounds service for carriage of Grade A products and less, in accordance with 46CFR subchapter D with an endorsement for type II and III hulls meeting the hull strength, subdivision and intact stability requirements according to 46CFR subchapter O.

Design of the hull and cargo tanks will allow carriage of liquid cargoes having a vapor pressure of up to 3.0 psi.
