Western Union Int'l
To Market New
MARISAT System
A specially designed maritime
satellite communications system
is being marketed by Western
Union International, Inc. (WUI),
One WUI Plaza, New York, N.Y.
10004.
The system, called MARISAT,
was described by Roy K. Andres,
WUI's vice president for planning,
selected for
reliability
repeatability
and lowest
maintenance
Rig built by: Marathon LeTourneau,
Enterprises, Slidell. La.
at a recent press conference held
at the Whitehall Club in New
York City.
Developed by WUI in partner-
ship with other communications
organizations and with the back-
ing of the U.S. Navy, MARISAT
has been utilized on an introduc-
tory service basis to shipping for
the past year.
Core of the system are three
geostationary orbits 22,300 miles
over the equator covering the At-
lantic, Pacific and Indian Oceans.
systems
The satellites provide contin-
uous ultra-high-frequency com-
munications to the U.S. Navy in
all three oceans.
Links to the Navy installations
with the mainland U.S. are two
large shore stations with 42-foot-
diameter antennas, one each in
Connecticut and California. A
third will be in service in the
Indian Ocean area later this year.
Under the system, ships com-
municate instantaneously, using
a four-foot stabilized antenna
beamed to the satellite which am-
plifies the signal and repeats it
to shore stations.
Telex calls from ships are au-
tomatically interconnected by a
U.S. international record carrier
to any Telex machine throughout
the world.
According to Mr. Andres, the
system is available for $55,000
per complete unit, excluding in-
stallation costs. It can also be ob-
tained on a lease basis, he added.

Maritime Approves
CDS For Purchase
Of Spare Tailshaft
The Maritime Subsidy Board
has approved construction-differ-
ential subsidy (CDS) for the pur-
chase of a spare tailshaft to sup-
port four 89,700-deadweight-ton
tankers built for the Third Group,
Inc.
The tailshaft will cost $52,500,
of which the Government will pay
$19,147. The tankers were built
with CDS assistance by National
Steel and Shipbuilding Corpora-
tion, San Diego, Calif., at a cost
of approximately $28 million each.
The last vessel was delivered De-
cember 30, 1976.
"Mr. Si" rig, owned and operated by Fluor Drilling
Service, Coral Division, New Orleans, La.

Balanced deck loading is vitally important on this "Jack-Up" type
drilling rig - a factor strongly influenced by tank content and re-
lated weight distribution. Equally important is a continuously ade-
quate inventory of diesel fuel, lube oil, potable water and drilling
water to service day-by-day operating requirements.
Fourteen service storage tanks are built into the deck of the "Mr.
Si" - an exploratory oil rig currently operating in the Gulf of Mexi-
co - and each tank is continuously monitored by a Gems Tank
Level Indicating System, selected and specified by the owners.
Factors influencing Gems selection included reliability, repeatability
(system accuracy consistently within 1/2" of liquid level), ease of
installation and a demonstrably low need for maintenance.
The Gems operating principle is ingeniously simple and trouble-
free: a tubular transmitter, acting as a voltage divider, is traversed
by a magnetic float, which rises and falls with liquid level and
transmits continuous level information to a remote read-out meter
(receiver). Transmitters can be furnished in a wide variety of mate-
rials and configurations compatible with most media and the most
difficult tank depths and profiles. Receivers are either dial or digital
types, and secondary (slave) units are available if required.
The "Mr. Si" installation employs 14 flange (carbon steel) mounted
transmitters with stainless steel stems and Buna N floats. Multiple
receivers are housed in a special table-top console designed and
built by Gems to customer specifications.

Hydroplaning
Bad news on a
wet highway...
good news in a Cutless
rubber bearing
Let a paper-thin film of water get
between the road surface and your tires
and you lose the road friction that lets
you keep your car under control.
Put a similar film of water between the
propeller shaft of your boat and the
tough, resilient Goodrich rubber of a
Moffitt Cutless marine bearing and you
practically eliminate friction that wastes
valuable horsepower and fuel.
The Moffitt "Water Wedge" design
produces a "hydroplaning" film as the
shaft turns. And maintains the film as
long as the shaft rotates. Works in any
kind of water... salt or fresh.. .clean or
silt-filled.
Needs no oil or grease that could lead to
water contamination. And no seals to
adjust and replace.
Look out for highway hydroplaning.
Look into the friction-free
"hydroplaning" that makes a Moffitt
bearing the cleanest, most trouble-free
rubber marine bearing you can buy.
Available in a full range of shaft
diameters and load capacities.
