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. critical issues like fuel conservation and ocean pollution.
