Daewoo Christens Two Jackup Rigs For Dual Drilling Co.

Two jackup drilling rigs were christened recently in a ceremony held at Daewoo's Okpo shipyard situated on the southern tip of the Korean peninsula.

The Friede & Goldman L-780 Mod II-type rigs, which we're ordered byDUal Drilling Co. of the U.S. in September 1981, were named Dual Offshore Rig 38 and Dual Offshore Rig 42, respectively.

Each of the units has the principal 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 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. Priddy, chairman of Dual Drilling Co.

Korean shipbuilders are now constructing 10 percent of the rigs presently on the world orderbook.
