Circle 59 on Reader Service Card

Gibbs & Cox, Inc. is a multi-disci- plinary engineering firm having as its primary focus naval architecture and marine engineering. It is recog- nized worldwide for its work in the design of naval surface combatants and commercial ships, and is cur- rently 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 sea- water; cooling the ship's central fresh water; cooling electronic equipment; or recovering heat from condensate. They are far more effi- cient 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.

HamiltonJ et's advanced waterjet of hot and cold liquids is virtually impossible.

Low fouling rates reduce cleaning require- ments 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 temper- atures 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-S-

Applications include main propulsion for high speed pa- trol, riverine assault, RIB assault and rescue and other multi-mission craft, as well as wide use as a loiter/ boost propulsor in conjunction with 901C; vibration testing per MIL-STD-167-1; and ASME U stamp per Sec. VIII Div. 1.

Hellan fluid strainers have been chosen by the Navy to replace du- plex strainers on all CG-47 cruisers to protect radar, sonar, GTC, pha- lanx, LPAC, etc. Hellan says its fluid strainers need little or no main- tenance; are self-contained, so sail- ors are not exposed to harmful de- bris or chemicals; weigh 60 to 70 percent what duplex strainers weigh; and can be cleaned in 30 seconds without disassembly. The company claims this translates into major cost savings. In the 18 months since

Hellan strainers were installed on the CG-47s, there have reportedly been no complaints. Hellan fluid strainers are approved by ABS, U.S.

Coast Guard and Navy.

The Navy is reportedly consider- ing Hellan strainers in place of du- plex strainers, starting with Flight

IIA of DDG-51 destroyers. Both the

Navy and private shipyards are also considering Hellan strainers for use on other Navy class ships.
