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.

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
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.
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.

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
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.
