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. Intermixing or cross-contamination 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-

An all new, American-designed high speed passenger vessel, named "Wild Thing," has gone into opera- tion in Virginia Beach, Va., carrying tourists on a one hour thrill ride at sea.

Wild Thing is of a new trade- marked design known as F.A.S.T.-l (fast air supported trimaran). The 901C; vibration testing per MIL-STD-167-1; and ASME U stamp per Sec. VIII Div. 1.

F.A.S.T.-1 is a new design that f the need for a low-technology, hij performance vessel.

Three elements make up t

F.A.S.T.-l design: three long hu with a flat bottom and five degi trim angle for lift; two tunnels wi a decreasing volume from bow stern for lift and air suspension; a; a large flat deck that can be used \ carrying anything from people freight.

The 97-foot Wild Thing, has a 3 foot beam and a four-foot draft. Wi

Thing is reportedly the fastest 15 passenger U.S. Coast Guard cen fied subchapter T-L vessel (approve for 150 passengers at 45 knots).

The vessel was built at Todd M rine in Norfolk, Va. for approx mately $2 million.

The Wild Thing's unique desig makes it useful for multiple applici tions, including: offshore crew/wor boat; oil rig support; personnel ferr diving/salvage/fire/rescue; drug ii terdiction; and unlimited configure tions for military requirements.

In designer Joshua W

Johnson's opinion, there are ver few American-designed high spee passenger ferries in operation in th

U.S. because of the assumed risk involved with taking a chance wit] a new design. "Everyone is copying everyom else," said Mr. Johnson. Mr. John son also cites the difficulty witl securing the financing to providf the funds necessary for buildini these vessels.

According to Mr. Johnson, build ing and designing the vessel didn'1 take nearly as much time as finding a sponsor for the vessel. (Mr. John- son said that he worked on the Wild

Thing's design for more than four years, but once a customer ap- proached him who was willing to contribute the funds needed to build the vessel, building commenced in 18 months.)

Mr. Johnson has also designed offshore racing power boats, sail boats, yachts and gun boats for for- eign navies.

At press time, American Water- ways is negotiating with Mr. John- son for additional vessels to be used as excursion boats to the San Juan

Islands.

They are reportedly looking at shipyards on the West Coast to build the additional vessels.
