Offshore Platform Workover Rig HXJ225

The Offshore Platform Workover Rig HXJ225 is a professional high-reliability offshore platform dedicated workover rig, designed and manufactured in full.

Product overview

The Offshore Platform Workover Rig HXJ225 is a professional high-reliability offshore platform dedicated workover rig, designed and manufactured in full compliance with API 4F, API 7K, ABS marine certification and ISO9001 international industry standards. Developed for 2000m-level offshore oil and gas platform well workover, completion overhaul, downhole accident treatment and old well stimulation operations, the rig adopts a highly integrated compact modular structure tailored for offshore platform limited space layout. It features lightweight high-strength structural design, professional marine salt spray corrosion resistance, wind and wave resistance, and platform load limit adaptation. Different from land rigs, this HXJ225 model focuses on high safety, low space occupation, easy offshore installation and stable continuous marine operation, serving as the core special equipment for routine maintenance and production improvement of offshore fixed platform and jacket platform oil and gas wells.

Core innovative advantages and structural features

Offshore Ultra-compact Modular Integration Design

Optimized split modular layout adapted to the narrow installation space and load-bearing limit of offshore platforms. All functional units including derrick, drawworks, power system and control cabin are reasonably compacted with lightweight reinforcement design. It avoids excessive platform deck occupation, reduces overall deck load pressure, and realizes fast hoisting, splicing and commissioning for offshore replacement and installation operations.

Full Marine-grade Anti-corrosion & Weather Resistance System

The whole machine adopts offshore heavy-duty anti-corrosion coating system, and key structural steel undergoes marine specialized passivation treatment. Electrical, hydraulic and sealing components are upgraded with salt spray resistance, moisture-proof and mildew-proof configurations, effectively resisting long-term marine high humidity, salt spray and ocean wind erosion to prevent equipment aging and failure.

High Wind-resistance & Anti-vibration Marine Structure

The derrick and base support structure are optimized through offshore working condition finite element simulation, with enhanced wind resistance and structural anti-vibration performance. It can adapt to offshore conventional wind wave disturbance and continuous shaking working conditions, maintaining stable load-bearing and operating accuracy during long-term offshore cyclic workover operations.

Explosion-proof & High-safety Marine Grade Configuration

The whole electrical system adopts offshore explosion-proof standard configuration, matching marine hazardous area safety specifications. Equipped with multi-level safety interlock protection, overload emergency stop, pipe string anti-drop and fire-proof isolation devices, it fully meets offshore platform high-standard safety operation management requirements.

Low Maintenance & Marine Environment Adaptability

The power transmission system adopts mature and reliable marine customized structure with low failure rate. Key wearing parts adopt international universal marine standard specifications, supporting convenient offshore replacement and maintenance. The whole machine adapts to 24-hour continuous uninterrupted operation mode of offshore oilfield platforms.
