The first Marathon LeTourneau Gorilla class jack-up rig Rowan Gorilla I was recently towed to its first drilling assignment off Nova Scotia. The rig, of which two more are on order, is among the largest and most costly self-elevating units 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 2,750 tons for drilling consumables and 42,265 ft of deck space. Its ample storage capacity, along with its 503 ft length and special design features makes the rig compatible with hostile offshore areas where it can continue drilling for long periods unattended.
