Italsomeets the requirementsofeasyinstallation,dismantlingandmaintenance.Modularizationcanberealizedinallthefollowingpartsofthedrillingrig:rigfloor,drawworks, mast, basement, mud pump system, solid control system, andauxiliarysystemwithahighlevelofmodularization.Thedrawworksusessingledrumdrawworks,and themainbrake isadiscbrakemechanism(singlediscordoubledisc)Thederrick is towertypeorhasamultisection telescopingstructure,whichcanbehydraulicallyriggedupandriggeddown. This rig has high reliability, strongwindresistant ability and excellent seawatercorrosion resistant performance. Inaddition, its explosionproof capabilityalsomeetsoffshoredrillingrequirements.Something is designed for pollutionszerodischarge.The correlative ACS certificate, such asCCS,DNV,canbeobtainedaccording totheclientsrequirements.
