Our offshore workover rigs are specifically engineered for workover operations on offshore oil production platforms. Available with diverse power systems—including diesel engine drive, AC variable-frequency electric (VFD) drive, and electromechanical compound drive—our product line spans six series from HXJ90 to HXJ225. The rigs feature either K-type telescopic masts or tower-type structures, supported by a robust truss-type substructure. Additionally, the drawworks are equipped with hydraulic disc brakes to ensure precise and safe operation.
The main body of the offshore workover rig comprises the substructure, mast, drawworks, power system, hydraulic system, and electronic control system. To maximize durability in harsh marine environments, the primary components of the mast are treated with a hot-dip galvanizing process for superior corrosion resistance.
Equipped with an advanced traveling system that enables both longitudinal and lateral movement, allowing the rig to seamlessly accommodate cluster wellhead operations.
Features a highly stable, guyline-free design with a two-section nesting structure and hydraulic telescoping mechanism, complete with double-sided opening capabilities.
Designed with a novel architecture and excellent performance, this single-drum drawworks features LEBUS grooving and is equipped with dual braking systems (hydraulic and pneumatic disc brakes) for enhanced safety.
Integrates the rotary table and drawworks drive into a unified design. By lowering the rotary table drive unit beneath the drill floor, this configuration significantly increases the open workspace on the drill floor surface.
The rig features a telescoping nesting mast, which combines ease of installation with exceptional load-bearing capacity, ensuring highly safe and reliable operations.
Key structural components of the mast undergo hot-dip galvanizing treatment, significantly enhancing resistance to corrosion, salt spray, and high humidity in demanding offshore conditions.
All primary control systems are centralized within an integrated driller's cabin, providing operators with a highly convenient and comfortable working environment.
Adopting a modular design, the structure facilitates streamlined transportation and rapid on-site installation. Furthermore, the integrated traveling system enables both lateral and longitudinal movement of the entire workover rig.
The company is equipped with large-scale CNC gantry boring and milling machines, advanced machining centers, Lebus groove lathes, and other heavy-duty processing equipment. This robust manufacturing infrastructure fully meets the stringent production requirements for offshore workover rigs.
Featuring rational power matching and integrated electrical, pneumatic, and hydraulic control technologies, our systems are engineered to fully satisfy the rigorous demands of modern drilling and workover processes.
We maintain a strong after-sales service network capable of providing reliable domestic and international support, ensuring comprehensive product protection throughout its entire life cycle.
