Extending the drilling season beyond the open water period in the Arctic is the primary driver behind a new jackup concept designed to operate in light ice conditions. The defining feature of the Arctic jackup is its telescopic leg that protects the drillstring from ice loads and is adjustable for depths down to approximately 50 m. Developed at the University of Stavanger in Norway as part of a graduate thesis and presented in a technical paper at the 2014 Arctic Offshore Technology Conference in Houston, the hull of the jackup is ship-shaped and borrows from icebreaker technology to withstand hits from drift ice as it is transported to an Arctic drilling location. The design of the Arctic jackup's other supporting legs are also unique and key to enabling the system to remain in ice conditions for more than a month after the open water season has ended. The design seeks to provide operators with an extra 30 to 40 days on the back end of the season--enough time, the designers say, to drill and test a new well in the same season.
