Burton Shipyard Constructing 200-Foot Offshore Vessels For Offshore Logistics, Inc. Two of the world's largest and the oil in- dustry's fastest ocean support vessels are under construction for Offshore Logistics, Inc., La- fayette, La. The vessels, named Great Republic and Joseph Conrad, are 200 feet in length. They were designed by Offshore Logistics to provide the offshore oil operator with 20 miles per hour cle ivery of over 5,000 cubic feet of bulk materials in below deck storage or 800 tons of drill pipe, tubing, or other deck cargo. These requirements are considered to be es- sential, as the search for offshore oil expands to the remote areas of the world. Dependability of the equipment was given high priority in the design, and a complete reserve system has been included for all major components. The Great Republic and Joseph Conrad are each powered by two General Motors EMD engines furnishing 5,600 total horsepower. The use of high horsepower propulsion system and a hydraulically driven towing and anchor winch, give the vessels long-distance towing capabilities. The first of the two new ships will be launch- ed in July, and the second, in September of this year. Both are being built by Burton Ship- yard, Inc., Port Arthur, Texas. In addition to these vessels, Offshore Logis- tics has under construction two 175-foot towing and supply vessels with 4,000 horsepower at Zigler Shipyards, and two 185-foot towing and supply vesse's with 5.600 horsepower at Halter Marine Services, Inc. These were designed fol- lowing the same concept of large capacities with extremely fast delivery speed. They will be completed during July and August of this year and will be added to the international fleet. The company also has six vessels under con- struction for addition to its domestic service. Offshore Logistics, Inc., presently owns and operates 32 crew and supp'y vessels in the Gulf of Mexico from operating headquarters in Mor- gan City, La. Executive and administrative headquarters are located in Lafayette, La. The company recently established an office in Sing- apore to serve the oil industry in southeast Asia, and is considering further expansion of its activities.
