$35-Million Two-Rig

Contract For Ingalls

Keyes Offshore, Inc. of Hous- ton, Texas, and the Ingalls Ship- building Division of Litton In- dustries recently announced an agreement for the construction of two offshore oil drilling rigs at

Ingalls facilities in Pascagoula,

Miss.

Keyes Offshore president Bill

Keyes said the first of the self- elevating "jackup" rigs will be ready for drilling operations in early 1981. Value of the two-rig construction contract with Ingalls is about $35 million.

Len Erb, senior vice president of Litton Industries and president of Ingalls, said work on the rigs would begin immediately with de- tail design and material and equip- ment procurement. Fabrication will start in May.

Designed by the naval archi- tectural firm of Friede and Gold- man of New Orleans, La., the rigs will be capable of operating in water depths of up to 300 feet, and will be able to drill to depths of 20,000 feet. The rigs' self- elevating feature, a jacking sys- tem which allows the hull of the structure to raise or lower itself on its support legs, will provide the units with maximum flexibil- ity for ocean transit and opera- tion positioning.

With accommodations for 56 personnel, the 5,500-ton mobile units will be 180 feet long and 175 feet wide. In addition to the two new rigs being ordered from

Ingalls, Keyes has two other drill- ing units under construction.

Ingalls, a designer and builder of marine structures for defense and commerce since 1938, will construct the new rigs at its 800- acre facility in Pascagoula, Miss.

The first rig will be delivered to

Keyes in March 1981, and the sec- ond in May 1981.

Singapore Signs Contract

For Imodco Harbor Terminal

The Port of Singapore Author- ity has signed a contract for

Imodco to design and engineer a

Single Point Mooring terminal system to be anchored in 32 me- ters (about 105 feet) of water in

Singapore Harbor.

The single grade buoy will be capable of mooring fully loaded tankers of up to 320,000 dwt for the discharge of crude oil, and is scheduled for completion and de- livery exactly 71 •_> months after the mid-December contract award.

Design of the 12.5-meter diam- eter (about 41 feet) terminal sys- tem will include a telemetry con- trol monitoring unit and calls for withstanding such storm condi- tions as a wind velocity of 32 meters per second and wave heights of 2.5 meters (about 8 feet).

The Port Authority project is the second for Imodco in Singa- pore. A CALM for ESSO Sing- apore Private, Ltd., for handling crude oil tankers of up to 252,000 dwt, has been in operation since 1970.
