on speculation; others order new rigs only after they have been committed.

The construction activities at

Santa Fe Drilling Company, head- quartered in Orange, Calif., are probably typical of the industry.

New construction by Santa Fe is unusual only in the diversity of equipment being ordered.

When Santa Fe Rig 124 (photo) went to work for Arco-Indonesia in the Java Sea earlier this year, it marked the first of eight new mobile offshore drilling units scheduled to go into operation for the company in the early 1980s.

Santa Fe has seven other ma- rine units either on order or un- dergoing conversion, at a cost in excess of $350 million. (An addi- tional 13 land rigs are on order at a cost of $92 million, making the grand total $442 million.)

When this phase of construc- tion activity is completed, Santa

Fe will be operating 34 marine units and 74 land rigs, for a total of 108 drilling units. Most of these rigs are working overseas in 15 different nations, primarily in Venezuela, the Middle East, the

North Sea, Africa and Southeast

Asia. Santa Fe's domestic opera- tions are in Texas and Louisiana.

Now in design or under con- struction for Santa Fe are three large semisubmersibles, a trio of three-leg jackups similar to Rig 124, and a swamp barge. Here is a breakdown:

Rig 130. This semisubmersible is the former Choctaw I, the world's first twin-hull, column- stabilized pipelaying and derrick barge. It was built in 1969 and performed construction work from Australia to the North Sea for 11 years for Santa Fe Engi- neering & Construction Company, a sister company to Santa Fe

Drilling. The barge is presently undergoing conversion at the

Avondale shipyard near New Or- leans. Upon completion in August,

Rig 130 will begin a two-year drilling contract for Cities Serv- ice.

Rigs 135 and 140. These large, all-weather semisubmersibles will be modified versions of the En- hanced Pacesetter series designed by the marine architectural firm of Friede and Goldman of New

Orleans. They will be capable of operating in such hostile environ- ments as the Gulf of Alaska and north of the 62nd parallel in the

North Sea. Both are being built in South Korea by Daewoo Ship- building & Heavy Machinery Ltd. at its Okpo Island shipyard near

Pusan. Rig 135 will be delivered in November 1982 and Rig 140 the following March. Both of these $80-million units are com- mitted for work.

Rigs 127, 134, and 136. These three jackups, under construction at China Shipbuilding Company,

Kaohsiung, Taiwan, are sched- uled for completion in April 1983,

December 1983, and June 1985.

They are committed to work ini- tially for Arco, Union Oil, and

Gulf of Suez Petroleum Co., an affiliate of Standard Oil Co. (In- diana). They, like Rig 124, are modified versions of the L-780 se- ries cantilevered jackups de- signed by Friede and Goldman.

They are capable of drilling in 250 feet of water to depths 20,- 000 feet below the seabed.

Rig 132. This unit will go to work this summer as a swamp barge in the Orinoco Delta of

Venezuela. Rig 132 is the former

Santa Fe launch barge Shawnee.

It is being renamed the Orinoco I, and is committed for three years to the Venezuelan oil company

Lagoven.

The seven marine units and 13 land rigs being built for Santa Fe

Drilling are being designed and rigged up by Santa Fe Engineer- ing Services Company, another sister company. In addition, this

Engineering Services group is de- signing and rigging up 11 other drilling rigs for outside clients.

Nine are land units for two Ven- (continued on page 42)
