ODECO Orders World's Largest Semi-Submersible Drill Rig From Mitsubishi Industries Mitsubishi Heavy Industries, Ltd., recently received an order for what the shipyard calls the world's largest offshore semi-submersible oil-well drilling- rig, Ocean Prospector, from ODECO International Inc., New Orleans, La. The rig, to be constructed on four cylindri-cal lower hulls, with the two inboard hulls torpedo-shaped, will have 16 columns erected on these hulls. The living quarters, engine room and drilling deck are designed to be sup-ported by these columns. Measuring approximately 341-feet in length, 262-feet in width and 125-feet in height, the rig will have a drilling deck of approximately 262-feet by 187-feet in area. Weight of steel used for the construction of the rig will amount to 8,000 tons. It will be equipped with a 2,800-hp propul-sion system in each of the two torpedo-type hulls, and will be capable of self-navigating at a speed of 6 knots. It will also be equipped with four 105-hp anchor windlasses, and four 1,600-hp diesel generators. The living quarters will be capable of accommodating 66 persons. The rig, with a drilling capacity of 26,000 feet, will be capable of drilling oil wells in con-tinental shelves up to a maximum depth of 650-feet under water in a semi-submerged po-sition. After completion, which is scheduled for November, 1970, the rig will be engaged in oil-well drilling in Southeast Asia. To date Mitsubishi has received other orders for seven offshore oil-well drilling rigs. United Fruit To Transfer Three Ships To Dutch Flag The Maritime Administration has approved the request of United Fruit Company to trans-fer to Dutch registry three 5,000-ton refrig-erated ships, each over 22 years old. The vessels will be transferred to Carai-bische Scheepvart Maatschappif, United Fruit's Dutch affiliate, for continued operation as banana carriers and general cargo carriers in worldwide trading. They are the Santo Cer-ro, the Quisqueya and the Morazan. In its application the company noted that it had lost $l-million last year in operating the small and relatively slow vessels. United Fruit also told the Federal agency that the vessels could no longer be economically employed un-der the United States flag. The ships are the second group of three ves-sels, each to be transferred out of the fleet of 18 ships of that type built immediately after World War II. OIL PURIFIERS ELECTRIC MFG. CO.
