BETHLEHEM LAYS KEEL FOR TEMPLE RIG — The keel was laid recently by Bethlehem Steel's Sparrows Point, Md., shipyard for a Temple Drilling Company mobile jackup oil rig, the Cheyenne. The new rig will be similar to the Comanche, shown above drilling for Gulf Oil Company in 50 feet of water southwest of New Orleans, which was delivered by Bethlehem's Beaumont, Texas, shipyard last December. The Cheyenne, which will be capable of drilling in a water depth of 200 feet, is scheduled to be delivered by the Sparrows Point yard in April 1982.
