Dual Offshore Rig 42, respec- tively.

Each of the units has the prin- cipal dimensions of 180 feet in length, 175 feet in breadth, and 25 feet in hull depth, with a leg length of 416 feet 8 inches. The rigs each have accommodations for 92 men. The jackup drilling rigs are designed to drill to 20,000 feet at a water depth of 250 feet, and withstand winds up to 100 knots and wave heights of 57 feet.

Daewoo, which is now building the largest number of drilling rigs in Korea, constructed the drilling units in a record period of 11 months. The units were the first jackups to be built by a

Korean shipyard. The first rig was delivered recently and the second is scheduled for delivery this month.

The jackup Dual Offshore Rig 38 is one of two being built by Daewoo Shipyard.

The drilling rigs are also the first jackups for Dual Drilling

Co. They will be deployed in the

West Java Sea off Indonesia, where they will be operated by

ARCO Indonesia under a lease contract, according to R.T. Prid- dy, chairman of Dual Drilling Co.

Korean shipbuilders are now constructing 10 percent of the rigs presently on the world or- derbook.
