Coastal Iron Works, Inc. of Corpus Christi, Texas, recently announced the christening of its new steel floating drydock. The drydock is named Mr. Pat after one of the founders of the company, E.J. Patterson. The drydock is now in service.

Mr. Pat is the largest drydock operating on the Gulf Coast south of the Galveston- Freeport area. It was built specifically to haul out the supply boats, tugs, crew and utility boats, and barges which service the offshore drilling industry in the Gulf of Mexico.

Rated at 2,500-tons lifting capacity, the drydock is 200 feet long, and 68 feet between the wingwalls. To insure rapid, highquality repairs and maintenance, a slip 30 feet deep was dredged inland and bulkheaded. This enables cranes and equipment to work from three sides of the dock. The ballast system is operated by one person using a sophisticated console in the control house located on top of the port wingwall. The system includes 12 independent ballast tanks using six Framo hydrostatically driven, submersible, reversible pumps with a total capacity of 36,720 gpm. The ballast valves are 12-inch Hills-McCanna butterfly valves with Bettis subsea service actuators.

The new drydock is in addition to Coastal's 1,000-ton railway system and 100-ton syncrolift, and approximately 600 feet of wet dock. Coastal Iron Works, Inc. has been serving the marine field in and around Corpus Christi for more than 35 years. The officers are C. Burney, chairman of the board, J.R. Hubenak, president, T.L. Patterson. vice president and secretary, M.I. Smith, vice president, and C.H. Nelson, treasurer. J.C. Ardoin is shipyard superintendent.
