American Trading Seeks Title XI Aid To Build 4 OBOs The Maritime Administration announced that American Trading Transportation Co. of 555 Fifth Avenue, New York, N.Y., has ap- plied for a Title XI guarantee to aid in financing the construction of four 80,000-deadweight-ton ore/ bulk/oil (OBO) carriers. The ap- plicant, a subsidiary of American Trading and Production Corp., esti- mates that the vessels will cost ap- proximately $34,993,000 each, and has filed for both construction and operational differential subsidies.

Levingston To Build Semisubmersible Unit For Santa Fe Int'l Santa Fe International Corp., Orange, Calif., has announced plans for immediate construction of a semisubmersible drilling unit designed to operate in maximum water depths of 1,500 feet. . The unit, Blue Water No. 4, will be built at Orange, Texas, by Levingston Shipbuilding Co. De- livery is scheduled for October 1974. Santa Fe president E.L. Shannon Jr. said it will be an improved ver- sion of the company's Blue Water No. 3, which was worked in the North Sea the past year. Mr. Shannon said it is being built in anticipation of an increased de- mand for rigs capable of drilling in deeper waters of the Gulf of Mexico. Initially, it will be out- fitted with marine riser and blow- out preventer controls to work in 600-foot water depths. For water depths to 1,500 feet, the Blue Water No. 4 will use a combination chain/wire mooring system with eight 15-ton anchors. The entire mooring system will be carried on board the unit during field moves, eliminating the re- quirement for an auxiliary vessel to handle the chain and anchors. In overall physical 'dimensions, the unit will be identical to the Blue Water No. 3, while design modifications will provide increas- ed stability and improved motion characteristics. It will be equipped with a diesel- electric rig capable of drilling to depths of 25,000 feet and will in- corporate the latest design in sub- sea equipment. Air-conditioned quarters will be provided for 68 persons in addition to a six-bed hospital. The vessel is designed to con- form with all regulations of the American Bureau of Shipping and other agencies governing the con- struction and operation of U.S.-fiag vessels. Principal dimensions and capa- cities of the unit include: overall August 19, 1973 13 length, 220 feet; overall width, 198 feet; height to deck, 83 feet; drill- ing draft, 40 feet; allowable deck load, 1,500 short tons; drill water storage, 5,000 barrels; fresh water (ship service), 1,200 barrels; po- table water (plus distillation units), 100 barrels; liquid mud (active) 1,200 barrels; diesel fuel,. 65,000 gallons, and bulk mud and cement (interchangeable), 2,400 and 4,800 cubic feet.
