Snubbing Units
Technical profile
This equipment is featured by simple structure, compact layout and light weight. It is fitted with hydraulic skidding base and integrated wellhead device, meeting the requirements for offshore cluster-well operation and integral movement. Its successful development has filled the void of high-end offshore hydraulic workover rig in China, with 8 national patents awarded.
It is an innovative stand-alone full-hydraulic workover equipment based on our research experience of offshore workover rigs and stand-alone snubbing units in combination with offshore platform workover operation need.
Compared with the conventional workover rigs with the mechanical drive,high mast and complicated structure, it is fully hydraulically powered.Hydraulic cylinders and hydraulic motors will accomplish the lifting,snubbing and rotating of tubing, with the advantages such as heavy load, large torque, optimized centralized control of operation console and convenient operation.
Suitable for high-dense cluster wells, small well site and offshore platform.
Modular lightweight design, the single module is less than 8T.
Rapid movement between wells, and the cost of installation and transportation is 30% less.
