The Offshore Platform Workover Rig HXJ315 is a heavy-duty high-load offshore platform dedicated workover rig, fully designed and manufactured in.
The Offshore Platform Workover Rig HXJ315 is a heavy-duty high-load offshore platform dedicated workover rig, fully designed and manufactured in accordance with API 4F, API 7K, ABS marine certification and ISO9001 international marine industry standards. Upgraded on the basis of conventional offshore workover rigs, this model is tailored for 3000m-level medium-deep offshore oil and gas well heavy-duty workover, full well overhaul, complex downhole accident treatment and high-efficiency reservoir stimulation operations. Adopting reinforced compact modular marine structure, it features ultra-high load-bearing capacity, upgraded wind and wave resistance, full marine explosion-proof configuration and extreme marine environment adaptability. Breaking the load limit of small-tonnage offshore workover equipment, the HXJ315 perfectly balances large load performance and platform deck space adaptability. It is the core professional equipment for heavy-duty maintenance and secondary development of medium-deep offshore fixed platforms, jacket platforms and marine marginal oilfield wells.
Equipped with customized JJ315/43-A high-load marine derrick and reinforced integral base substructure, verified by full working condition finite element stress simulation. The whole bearing system is optimized for medium-deep offshore well heavy tripping and high-load workover conditions, with excellent structural rigidity, anti-deformation and fatigue resistance, meeting long-term high-intensity offshore cyclic operation requirements.
All steel structural components adopt heavy-duty marine multi-layer anti-rust and anti-corrosion coating and professional passivation treatment. Hydraulic, electrical and sealing components are upgraded with high-grade salt spray resistance, moisture-proof and mildew-proof accessories. It effectively resists long-term erosion of offshore high humidity, salt spray and strong ocean wind, avoiding equipment aging and performance attenuation in harsh marine environments.
The derrick and base support structure are optimized for offshore strong wind and wave disturbance working conditions, with upgraded overall wind resistance grade and structural anti-vibration and shock absorption performance. It can maintain stable operation accuracy and structural safety under frequent marine wind wave fluctuations and continuous platform shaking, adapting to complex sea area meteorological conditions.
The entire electrical control system complies with international marine hazardous area explosion-proof standards, equipped with multi-level safety interlock, overload emergency stop, pipe string anti-drop, well control linkage and fire isolation protection devices. The whole machine realizes full-process safety monitoring and risk early warning, fully meeting strict offshore platform safety management specifications.
Adopts mature high-power marine dedicated transmission system, with stable power output and strong variable-load adaptability. The structural layout is optimized for offshore maintenance convenience, with universal international marine standard wearing parts, reducing offshore maintenance difficulty and downtime, and supporting 24-hour continuous uninterrupted marine operation.
