Latest Rig Order From Santa Fe Drilling Brings Total To $442 Million

Santa Fe Drilling Company has ordered a second $80-million allweather, semisubmersible drilling unit, bringing to $442 million the value of new drilling equipment on order. E.L. Shannon Jr., chairman of the parent Santa Fe International Corporation, said the new unit brings to 20 the number of drilling rigs under construction or on order. These include 13 land and seven marine units. The two semisubmersibles, designated as Rigs 135 and 140, will be built by Daewoo Shipbuilding and Heavy Machinery, Ltd., Seoul, Korea, in Daewoo's Okpo shipyard. The first unit is scheduled for delivery in November 1982 and the second in March 1983. Each will cost about $80 million.

The semis are modified versions of the 9500 Enhanced Pacesetter series, designed by the marine architectural firm of Friede & Goldman, New Orleans. Both are designed for operations in severe environments such as the Gulf of Alaska or the North Sea north of the 62nd parallel. They will be capable of working in waters 1,500 feet deep and drilling to depths of 25,000 feet. Both vessels will be self-propelled.
