 for unrestricted worldwide ocean service. She was a 390 feet (118.9 m) long, 226 feet (68.9 m) wide, twin-hull design with a 12450 hp propulsion system. The rig's structure was designed to simultaneously withstand 100 knots (196 km/h) winds, 110 feet (33.5 m) waves, and a 3 knots (5.9 km/h) current. The derrick was fully enclosed with a heated drill floor permitting operations down to -35 C.

The rig had other advanced extreme-condition features as well. For example, the rig's columns were strengthened to withstand some ice impact and the marine riser had a feature similar to a cow-catcher to keep floating ice off the marine riser that connected the rig to the well on the ocean bottom.
