CAT J drilling rig

The specially-designed category J rig is able to operate at water depths from 70 to 150 meters and drill wells down to 10,000 meters. According to Statoil, it will be a workhorse primarily for drilling and completion of production wells. It is a tailor-made jack-up rig for operations in harsh environment on both surface and subsea wells in the shallow-water segments on the NCS.
