An Ensco drilling platform preparing to work for Anadarko Petroleum Corp. in the deepwaters of the Gulf of Mexico will be assessed for damage after it was struck about 3:15 a.m. Tuesday by a large storm wave. None of the 116 crew members aboard the platform were injured and there were no evacuations. A U.S. Coast Guard spokeswoman said crews for Ensco plan to inspect the semi-submersible Ensco 8506 rig, which is about 130 miles from Galveston, TX. The rig was knocked about 55 feet and began to take on water in one of the six flotation columns. The rig, in 3,000 feet of water, was stable. The rig is scheduled to begin operations in mid-July at a dayrate in the "high $540,000s," Ensco said. The dynamically positioned rig, built in 2012, is designed for water depths of 8,500-10,000 feet with a maximum drilling depth of 35,000 feet.
