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.
