Frank McGrath Named Chief Engineer At Peterson Builders in 1961 as a physicist in the Elec- trical Products Laboratory, and returned to the University of Minnesota to complete his doctor- ate in 1970. After joining the Martin Marietta Laboratories in 1970, Dr. Mularie returned to the Components and Devices Labora- tory of the Industrial Electrical Products Division of 3M in 1974, and joined the Central Research Laboratories in September 1978. Beker Maritime Seeks Title XI On Two Dredges To Cost $10 Million Beker Maritime Company, a Bradenton, Fla., subsidiary of Beker Industries Corporation, Greenwich, Conn. 06830, has ap- plied for a Title XI guarantee to aid in financing the construction of two cutterhead pipeline dredges. The 5,000-bhp vessels are to op- erate on the inland waters of Florida. If approved, the Title XI guar- antee would cover $8,750,000, or 87y3 percent of the total cost of $10 million. Deliveries have been scheduled for January and April 1981; the shipbuilder has not yet been de- termined. Frank McGrath Peterson Builders, Inc. recently announced that a number of changes had been made within their Engineering Department. The shifts made included assign- ing Frank McGrath to the posi- tion of chief engineer of the de- partment. He will have direct responsibility for the Hull De- partment, Mechanical/Piping/ Heating/Ventilation and Air Con- ditioning Department, Electrical/ Electronics Department and the Engineering Group. Mr. McGrath's former duties included the respon- sibility of serving as the Patrol Gunboat Program engineering production manager on the 190- foot Aluminum PGG program with the U.S. Navy. Additional engineering shifts made at PBI were comprised of promotions within three of the pri- mary engineering subdivisions at the shipbuilding facilities. They included the following promo- tions to department heads in their respective divisions: Gaylen La- Crosse-Mechanical / Piping / HV- AC; Richard Yedica-Hull/Outfit- ting; Eugene Hody-Electrical/ Electronics. As department heads, these three individuals will be re- sponsible for all design and draft- ing pertinent to their subdivisions, coordinating the engineering data that flows to and from production areas. W.M. Mularie Named Research Director For American Hoist A 10,000-psi jet of water promises to revolutionize routine on-board maintenance... especially rust and scale removal of surfaces to be painted. Butterworth Systems now offers a modern alternative to the age-old chipping hammer. It's their MARINE LIQUA-BLASTER* Dr. Wm. M. Mularie Robert P. Fox, president and chief executive officer of Amhoist (American Hoist & Derrick Com- pany), St. Paul, Minn., announces the creation of a new Corporate Research Department. Dr. Wm. M. Mularie has joined the new department as director of corporate research. He joined 3M Diesel powered pump of a MARINE LIQUA-BLASTER onboard a vessel. ultra-high pressure water- blasting equipment. Especially developed for shipboard use at sea, the MARINE LIQUA-BLASTER unit uses a diesel or electric powered pump to generate a 10,000-psi jet of water that is directed by a fail-safe, hand-held gun at the surface being descaled. "White-metal" cleaning. On a badly rusted surface, "water only" blasting removes scale and debris, leaving a surface that is acceptable for standard maintenance painting. If a moderate amount of sand is automatically added to the water jet, a surface can be "white-metal" cleaned more effectively and more efficiently than it would be with dry-sand blasting in a shipyard. With the MARINE LIQUA-BLASTER unit, a rust inhibitor can be added to protect the "white-metal" surface against oxidation before painting. Introducing the Butterworth Systems MARINE LIQUA- BLASTER* SHIP MAINTENANCE SYSTEM. Better than dry-sand blasting. Because of the high velocity of the water/sand jet, the sand impacts a rusted surface with a much greater force than with regular dry-sand blasting. The end result is faster cleaning using less sand. Respirators are not required since no dust is generated. Clean-up is also easier. Other shipboard cleaning. In addition to descaling rusted surfaces, a MARINE LIQUA-BLASTER unit can be used for a number of other on-board cleaning jobs. These include cleaning condenser and boiler tubes, oil spray from machinery, galley grease filters, clogged ports, and the like. For these jobs, as well as rusted surfaces, a variety of guns, lances, round and fan jet nozzles are available. Proven on-board use. The experience on a 69,742-DWT tanker, is typical of other vessels that have used MARINE LIQUA-BLASTER equipment. Here, it was first used to clean a badly rusted 550-square-meter poop deck. The job was done as routine maintenance with interruptions for bad weather and all-hands tasks. In a little over two weeks the poop deck was "white-metal" cleaned and freshly painted. Doing the same job in a shipyard would have cost $13,750 at $25 per square meter not including the incremental lay up time to accomplish this task, jjfc wbmm, • m.
