Three Rigs To Cost
$90.3 Million Approved
By MarAd For Title XI
The Maritime Administration
has approved in principle the ap-
plication by Global Marine Deep-
water Drilling, Inc., Los Angeles,
for a Title XI guarantee to aid
in financing the construction of
three jackup drilling rigs.
Global Marine has not yet de-
cided on the final configuration of
the three drilling rigs. However,
Marathon LeTourneau Company
of Houston has been contracted to
build the vessels, with deliveries
scheduled for May, August, and
December 1981.
Global Marine expects the ves-
sels to be employed to explore for
offshore hydrocarbon reserves in
the Gulf of Mexico. The drilling
rigs, depending on their type, will
be able to drill to 20,000 feet in
waters up to 250 feet deep, or up
to 25,000 feet in waters up to 300
feet deep.
The Title XI guarantee will cov-
er $67,735,000, or 75 percent, of
the vessels' total estimated cost
of $90,314,627.

Coast Guard Rules On
Steering Failure Alarms
To Be Enforced Soon
New U.S. Coast Guard rules
will require most ships — tenta-
tively those over 1,600 gross tons
—with power-driven main or aux-
iliary steering gear to be equipped
with advanced steering failure
alarm systems.
The new rules, which are ex-
pected to be put into force within
six to eight months, require the
steering failure alarm system to
have an audible and visual alarm
that provides a signal in the
wheelhouse when the actual po-
sition of the rudder differs by
more than 5 degrees from the
rudder position ordered by the
helm. The maximum delay per-
mitted under the regulations
would be 30 seconds for an or-
dered change of 70 degrees, or 5
seconds for a change of 1 degree.
For ordered changes between
1 and 70 degrees, the Coast Guard
has mandated a formula under
which the maximum time delay
allowed is computed. For an or-
dered change of 10 degrees, for
example, the maximum delay be-
fore the alarm must sound would
be 8.26 seconds. The steering fail-
ure alarm system must also be
separate from and independent of
each steering gear control sys-
tem, and must have a separate
power supply.
"Based on our knowledge of the
current steering failure alarm sys-
tems now on the market, we be-
lieve that the Sperry system is
the only one immediately available
which will meet all the require-
ments," said Henry Johnston,
marketing manager for Sperry's
Marine Systems Unit. Marine
Systems, which developed the
steering failure alarm system, is
an operating unit of the Sperry
Division of Sperry Corporation.
The Sperry steering failure
alarm system contains patented
circuits which respond almost im-
mediately to a discrepancy be-
tween the rudder's actual position
and the position ordered. The sys-
tem uses a simulated rudder angle
calculation generated by a micro-
processor to determine where the
rudder should be during each
moment of a turn. When there
is a discrepancy of more than 5
degrees, an alarm is sounded im-
mediately. The system can also
compensate for worn or loose
steering gear which might not
respond as smoothly as a tightly
adjusted steering system.
