President Reagan And Sponsor Authenticate Keel Of 'Yorktown' At Ingalls As part of his participation in the bicentennial celebration of the Battle of Yorktown, Va., that ended the Revolutionary War, President Reagan authorized the start of hull construction on a new U.S. Navy cruiser to be named Yorktown (CG 48). In the upper photo, the President and Secretary of the Navy John F. Lehman look on as Mrs. Mary Mathews, sponsor of the Aegis guided missile cruiser, initials a plaque that will become a perma- nent part of the ship. The Presi- dent also initialed the plaque, which authenticates the keel-lay- ing of the second ship in the Ticonderoga Class. Prior to the ceremony at Yorktown, employ- ees of Ingalls Shipbuilding Divi- sion of Litton Industries in Pas- cagoula, Miss., the builder of the ship, positioned the first hull sec- tion or "keel" onto its blocks, signifying the beginning of con- struction. Marathon Launches Jackup Penrod 86 At Brownsville Yard These four frames capture the launch sequence of the Penrod 86, a class 82-SD-C self-elevating off- shore jackup drilling platform built by Marathon Manufactur- ing Company, Houston, Texas. The shallow-draft cantilever drilling unit was launched re- cently at Marathon's Gulf Marine Division yard in Brownsville, Tex- as. The rig is rated for water depths up to 250 feet. When the remaining sections of its three triangular legs are added, thev will be 360 feet tall. The derrick and other drilling components have yet to be installed. The rig's cantilever design lets the derrick move out beyond the stern so that the rig can work next to permanent offshore platforms without putting the weight of the drilling package on these plat- forms.

He said the company has long had a policy of acquiring vessels tailored to the specific needs of its customers and "the Cameron Express exem- plifies that policy. She is designed for extreme stability in rough seas, for speed and maneuver- ability as well as for maximum storage facilities," he said. New Compact Oil Water Separator From Sigma —Literature Available Sigma Treatment Systems, Inc., Chester Springs, Pa., is offering literature on a new addition to its line of marine pollution control equipment. The SH2 Oily Water Separator is U.S. Coast Guard cer- tified and meets IMCO standards. Designed with simplicity and minimum maintenance in mind, the single-tank units are fully automatic devices with only one pump. No disposable cartridges or other consumables are used. Permanent coalescer beds are au- tomatically backwashed every time separated oil is discharged.
