Gibbs & Cox, Inc.

Circle 5 9 on Reader Service Card Gibbs & Cox, Inc. is a multi-disciplinary engineering firm having as its primary focus naval architecture and marine engineering. It is recognized worldwide for its work in the design of naval surface combatants and commercial ships, and is currently engaged in the design of an advanced combat system frigate for Naval ships, fleet oilers, commercial containerships, tankers and dredges are successfully finding new ways to operate more efficiently at lower cost, by utilizing Tranter's unsurpassed plate-type heat exchanger technology. Schematics presented here illustrate typical ways they are doing it. Superchanger® plate and frame heat exchangers are used in a wide variety of shipboard applications—particularly for cooling main engine jacket water and cooling main engine lube oil with fresh water or seawater; cooling the ship's central fresh water; cooling electronic equipment; or recovering heat from condensate. They are far more efficient than tubular systems, and provide heat transfer coefficients from two to five times greater than those achieved by shell and tube units. They also require 10% to 50% less deck space and weigh up to one-sixth less. Superchanger units can be equipped with titanium plates which offer the best resistance to corrosion and erosion when exposed to seawater. Intermixing or cross-contamination the Republic of China and sealift ships for the U.S. Gibbs & Cox, Inc. is headquartered in New York City with offices in Arlington, Va.; Brunswick, Maine; and Pascagoula, Miss.

HomiltonJot Circle 6 0 on Reader Service Card HamiltonJ et's advanced waterjet of hot and cold liquids is virtually impossible. Low fouling rates reduce cleaning requirements for Superchanger units, that are designed for easy maintenance. They can be cleaned-in-place by backflushing, or quickly disassembled by hand, cleaned and put back in operation.

Platecoil® prime surface heat exchangers offer optimum temperature control. A Platecoil bank-in-tank unit provides wide interspaces for effectively passing solids while efficiently heating seawater containing oil from spills. Platecoil bayonet heaters provide a large amount of efficient primary heating surface in a single unit for maintaining desired temperatures in storage tanks. These heaters help promote convection currents for better heat transfer rates and tank temperature uniformity. Platecoil suction heaters provide immediate heating for pumping oil out of tanks.

Tranter plate-type heat exchangers can be supplied in full compliance with codes and specifications as required by the ABS; the U.S. Coast Guard; shock testing per MIL-SCircle 323 on Reader Service Card propulsion systems meet the standards of certifying authorities such as Lloyds and ABS, making them widely accepted by military and paramilitary organizations around the world.

This system uses a Reversible Converter Coupling (RCC) for reversing a fixed-pitch propeller and a clutch for efficient direct drive. The system is applicable for either high-powered gas turbine or diesel propulsion systems. Technical Products & Precision Mfg. Co.

Times Microwave Systems Circle 9 1 on Reader Service Card Times Microwave Systems (TMS), Inc., a division of Smiths Industries Aerospace and Defense Systems Inc., was founded in 1945 under the name Times Wire and Cable Company.

TMS has over 150 QPL Listings for Mil-C-17 coaxial cable and has been combining electrical expertise, exclusive compound development and fully swept VSWR and attenuation capabilities to address customized needs.

TMS is fully approved to the new Low-Smoke, Zero Halogen, flame retardant coaxial cables as specified in the latest revision of Mil-C-17, revision "G." TMS has also supplied a series of Low-Smoke RF cables which are specified on the Aegis class ships of the U.S. Navy. In addition to RF cable, TMS manufactures a wide variety of microwave cable assemblies per Mil-T- 81490. Many of these assemblies have been procured for use on the shipboard SLQ-32 anti-missile defense system, as well as other critical applications where sealed microwave assemblies are required.

Tranter Circle 92 on Reader Service Card Tranter Superchanger plate and frame heat exchangers with designated marine features are on 16 classes of U.S. Navy ships — particularly for electronic cooling — and are used in other applications on commercial containerships, tankers, barges and dredgers. Recent applications include engine cooling on the MTV Mississippi towboat owned by the U.S. Army Corps of Engineers and built by Trinity Industries, and the 224-foot (68.3 m)wooden MCM-14 Countermeasure Ship, Chief. Aside from being erosion and corrosion resistant, these titanium-plated heat exchangers offer deck space and weight savings; resistance to fouling due to high turbulence; ease of maintenance and repair; and favorable price. Superchanger units have recorded excellent test results in the fleet, and comply with ABS and U.S. Coast Guard requirements.

Wartsila Diesel Circle 93 on Reader Service Card Wartsila Diesel North America, Inc. (WDNA) has been active domestically in service and sales of its diesel engines since 1978. Internationally, Wartsila Diesel says it has grown to be the leading medium speed diesel engine manufacturer in the world. Wartsila is now transferring its Vasa series of engines to its newest production facility in Mt. Vernon, Ind. The Vasa series can burn all types of marine fuel oil, as well as natural gas. The Vasa 46 engine has now been tested to MILE- 23457 — reportedly with nearly twice the power of the next largest engine ever qualified to this rigorous Navy specification. WDNA provides extensive after market logistics support, in IGES, CALS, or any other format required. An example is the ELDOC system, which is a real-time, user-interactive multimedia system for maintenance, parts management, fault avoidance and training. See a demonstration of ELDOC and hear about WDNA's R&D activities at WDNA's booth at ASNE Day '94.

Westinghouse Circle 8 on Reader Service Card Westinghouse is one of the leading suppliers and manufacturers of marine diesel engines. The company provides low- and mediumspeed diesel propulsion systems.

Westinghouse diesels satisfy all sealift class standard equipment requirements. Westinghouse has been the Navy's marine gear sup- plier for more than 80 years, and has delivered a full spectrum of reduction gears from cost-competitive commercial designs to the most advanced systems for U.S. Navy submarines.

Westinghouse has support facilities around the world for training, service and parts. Westinghouse is currently the prime contractor in a program to develop an intercooled recuperated (ICR) engine for the U.S. Navy.

Westmont Industries Circle 9 4 on Reader Service Card Westmont Industries, Inc., a manufacturer of heavy material handling equipment, is nearing completion of a Navy contract for eight 100-ton barge cranes.
