Rowan Company's three deepwater jack-up Gorilla-class drilling rigs are designed for work in virtually all ice-free hostile environmental areas of the world. They will cost in excess of 85 million each, including owner-furnished drilling equipment. This, according to owners, will make them among the costliest jack-ups in the world. Another record being claimed by the Gorilla-class drilling units, is that they are the largest jack-ups in the world. Fully outfitted, a Gorilla contains 16,000 tons of steel. Its triangular hull measures 297 ft from bow to stern and 292 ft across the stern. The rig has a variable load of 2750 tons for drilling consumables and 42,265 sq ft of deck space. Its ample storage capacity, along with its 503-ft leg length, and certain design features, makes the rig compatible with hostile offshore areas, where it can continue drilling for long periods unattended.
