Rowan Offers Free Literature On Drill Rig 'Rowan Gorilla IV'

Rowan Companies, Inc. of Houston, Texas, is offering free literature on the design for the latest Gorilla rig, the Rowan Gorilla IV.

Constructed for Rowan Companies by Marathon LeTourneau Offshore Company of Vicksburg, Miss., the Gorilla rigs are a new and heavier class of rig, requiring twice the amount of fabricated steel used in former largest jackups. At 297 feet long by 292 feet wide, they are nearly 40 percent larger than the Marathon LeTourneau 116 Class jackups.

The brochure, which features color photos of the previously built Rowan Gorilla I, II, and III on the cover, contains drawings of Gorilla III shown in scale with Gorilla IV.

Equipped with 605 feet of leg, the Gorilla IV is capable of drilling in 450 feet of water in the Gulf of Mexico.

This exceeds the capabilities of any existing bottom-supported type jackup rig. Specifications for Gorilla IV are also listed, along with environmental criteria for both the Gulf of Mexico and the North Sea.
