Equitable Awarded $6-Million Contract For Tug Construction For Nolty T. Theriot, Inc. Cecil M. Keeney, president of Equitable Equipment Co., Inc., left, and C.R. Sanders, executive vice president of Nolty J. Theriot, Inc., sign the contract in New Orleans. Equitable Equipment Company, Inc., New Or- leans, La., shipbuilder, has been awarded a con- tract of approximately $6 million by Nolty J. Theriot, Inc., international offshore vessel oper- ator, to build three 149-foot 6-inch twin-screw 8,500-horsepower ocean tugs. They will be built to ABS Maltese Cross A-l, International Ocean Towing Service, Ice Strengthening Class C-l, Maltese Cross AMS Specifications. Each vessel will be fitted with Kort nozzles. The estimated total cost of the new tugs is $9.5 million. The vessels will be constructed at Equitable's Industrial Canal Shipyard. This contract will in- crease Equitable's present backlog of construction to approximately $50 million. Equitable is a wholly owned subsidiary of Trinity Industries, Inc. MarAd Contract Awarded To Breit Engineering For Tank Barge Cost Analysis Breit Engineering, Inc. of New Orleans, La.,, has been selected to perform life-cycle cost studies on various inland waterway tank barge designs for the Maritime Administration, it was announced by Robert J. Blackwell, As- sistant Secretary of Commerce for Maritime Affairs. The $51,000 fixed-price contract was award- ed to Breit to determine life-cycle costs of five alternative tank barge designs, including sin- gle-skin, double-wall, double-hull, single-skin with increased scantlings, and single-skin with selected local strengthening. Life-cycle cost estimates will be developed for tank barges with capacities of 1,200, 2,500, and 3,700 short tons. Additional estimates will be made of the costs of retrofitting single-skin tank barges to the greater alternative design standards. The Maritime Administration joined with the Coast Guard last July in a project to study the potential of various barge designs to re- duce water pollution from inland marine op- erations. In addition to the Breit contract, which will require about three months to complete, this effort includes development of a comprehensive profile of existing U.S. tank barges, examina- tion of Coast Guard records on barge spills to determine the effectiveness of alternative de- signs in minimizing cargo losses following casualties, and assessment of other economic factors that would bear on a choice between barge designs. Breit Engineering will be assisted by inland marine companies in acquiring necessary data to develop the cost estimates.
