Josef Walter Appointed General Manager Of Schottel-Hamburg Josef Walter Josef Walter was recently named general manager of Schot- tel-Hamburg, a subsidiary com- pany of Schottel-Werft Josef Becker GmbH & Co., KG, Spay/ Rhine, Germany. He was previously the techni- cal and commercial manager of the Comos Shipping Company, Vienna, Austria, where he intro- duced on the Danube River the first Schottel-Navigator units for the Comos fleet. Mr. Walter succeeds Heinz Dol- berg, who retired following 20 years of service. He will be an advisor to the company. Technical Paper And Brochure Available From MarineSafety International A new technical paper on mar- itime simulation training and in- formation on current training programs is now available from MarineSafety International of New York City. The paper, which was presented at the recent Sec- ond International Conference on Marine Simulation held at Kings Point, makes some important points in putting practical train- ing objectives in perspective with new simulator training hardware. Also available is a 12-page, full- color illustrated brochure describ- ing all of MarineSafety's training activities. This brochure also con- tains a description of the new ARPA (Automatic Radar Plot- ting Aid) training.

Although the initial integra- tion and testing of the GPS ca- pability for surface ships will be clone aboard a carrier, the U.S. Navy plans to use this program to determine GPS capability for all its military surface ships. In- tegration programs also are being conducted by the Navy to apply the GPS system to naval aircraft, helicopters, and submarines un- der separate contracts. Under the contract, Sperry will develop the hardware and soft- ware changes to integrate the GPS satellite receiver with the Ships Navigation and Aircraft 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* 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. Inertial Alignment System (SNA- IAS) now aboard 13 Navy carri- ers. The SNAIAS currently pro- vides ship's navigation informa- tion, as well as providing the ini- tial alignment of naval aircraft navigation systems prior to launching from the carrier. Sperry will build a laboratory model SNAIAS and then modify the SNAIAS aboard the Kitty Hawk aircraft carrier for at-sea tests of the system, which are scheduled to begin about October 1983. The NAVSTAR Global Posi- tioning System is a satellite-based ultra-high frequency positioning and navigation system, scheduled to be fully operational in 1986. Consisting of 18 satellites in or- bits 10,900 miles high, the sys- tem will be able to provide highly accurate three-dimensional posi- tion, velocity, and time data any- where in the world. 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.

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. Sand can cause sparking, so it should only be used in non-explosive environments. 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.
