Polar Pioneer is a Sonat/Hitachi-designed, semisubmersible drilling rig built in 1985. The rig is owned and operated by Transocean Offshore and was subject to main classification at Westcon in Olen in the autumn of 2004.
Upgrades were carried out during the stay at the yard to bring the rig in compliance with Statoil's (now StatoilHydro's) technical requirements for operations on the Snohvit field.
The Polar Pioneer has drilled production wells on Snohvit and several exploration wells for Statoil, Hydro and Eni in the Barents Sea.
