A heavy drilling rig, cold stacked for several years, recently underwent numerous structural, equipment, and computer upgrades for drilling ultradeep (8,000 m) gas wells in Germany. The technical improvements on the rig included supplementary installations and modifications to safety, quality, engineering, noise abatement, and environmental protection systems. With a maximal hook load of 700 tons, the drilling rig is one of the heaviest of its kind in Europe. The rig has a drilling depth range of 7,000--8,000 m, and the top drive system enables horizontal drilling. The paper describes the rig site, mast, top drive, substructure, draw works, power station, mud system, instrumentation, and other equipment.
