CSU160 Remote conbtrolled rig assist Snubbing unit

CSU-160 Unit

The CSU-160 Unit belongs to the latest generation of completely remote controlled rig assist Snubbing Units. It is designed to extend the capabilities of conventional and automatic rigs to allow safe working on pressurized wells. The CSU-160, one of the latest generation of rig-integrated snubbing units, combines safety and efficiency on board of conventional and automated jack-up rigs. The function of the CSU-160 is to insert or remove pipes while the well is under pressure.
