HydroComp Offers New Ship Propulsion Design Software Since 1984, marine professionals worldwide have chosen NavCad software as one of their principal design tools for the analysis and selection of engine, gear and propel- ler systems. HydroComp, Inc., Dur- ham, N.H., has produced NavCad 2.0—the most powerful NavCad software to date. The PC.-based NavCad system has been built around three main calculation routines: (1) vessel re- sistance; (2) propulsive coefficients and shaft power; and (3) propeller selection and analysis. Analysis methods are available for displace- ment vessels, planing craft, and barge trains. A comprehensive pro- peller analysis and an optimum pro- peller selection can be performed for a variety of open-wheel and ducted propellers. NavCad 2.0 also represents a new look and direction for NavCad soft- ware. An integrated, menu-driven data entry system provides the con- trol for the calculations—with data checking, context-sensitive help screens, and logical file handling. Also, NavCad 2.0 adds comparative analyses, graphing capabilities and CUMMINS POWERED LCU-2000 Cummins Marine diesels provide all on-board power for the U.S. Army Troop Support Command's Utility Landing Craft, LCU-2000.

Even a new user will find that they can instantly perform all of NavCad's functions through the pull-down menu system and data entry screens. NavCad 2.0 requires an IBM PC or compatible computer operating MS-DOS 3.0 or greater, with 640K RAM, and a hard disk drive. A nu- meric coprocessor, and EGA or VGA video are recommended. NavCad supports 5-1/4- and 3-1/2-inch formats.

Over 330,000 square feet of TNF Wall Panels, delivered on pallets in 75 large trucks, have been installed in 1,003 different combinations, to make installation fast, safe and noise resistant in all passenger ar- eas. During manufacture, transport and installation, the vast array of different colors and dimensions could only be managed by using a large computer program, from the moment the first steel sheet was ordered, until the last finished wall panel was in position. To fit the Fantasy properly, pan- els were delivered in 21 different colors, 49 different heights, 23 widths and utilizing 11 special shaped corner types. To insure successful installation, each individual panel was clearly marked, from the start of produc- tion until the people on site posi- tioned the panel according to instal- lation drawing. Rockment A/S, whose Rockwool TNF products are represented in the U.S. by the Waugh Co., Jack- sonville, Fla., has some of the most modern computer technology avail- able to help manage large projects.
