Offshore workover specifications

Innovation & Technology Advantages — What Sets SJ’s Specifications Apart

1. Full-Spectrum Workover Rig Capabilities

SJ offers a complete line of workover rigs with maximum hook load ranging from 585 kN to 2,250 kN, maximum workover depth up to 9,000 meters using 2-7/8″ drill pipe, and maximum installed power of 1,260 HP . Customers can choose between diesel engine drive or electrical motor drive systems. Single drum, double drum, and electric drive single-shaft drawworks are all available to match your operational requirements.

2. API Certification Across the Board — Real Compliance, Not Just a Logo

All SJ offshore workover equipment is designed and manufactured in compliance with API Spec Q1, 4F, 7K, 8C, 6A, and 16C. We are authorized to apply API monograms on products under these specifications, and our manufacturing process can be supervised by customers and inspected/certified by any third-party inspector .

Let me break down what each API spec means for your offshore operation:

API Spec	Covers	Why It Matters Offshore
API Spec 4F	Drilling and well-servicing structures (derricks, masts, substructures)	Ensures your mast won't fail under high wind loads (55 m/s rated) or maximum hook load conditions
API Spec 7K	Drilling and well-servicing equipment (drawworks, rotary tables, pumps)	Guarantees performance of all moving components under continuous marine duty
API Spec 8C	Hoisting equipment (traveling blocks, swivels, hooks, elevators)	Critical for safe pipe handling — failure here means dropped strings and potential injuries
API Spec 6A	Wellhead equipment	Required for pressure control interfaces with your platform’s Christmas tree
API Spec 16C	Choke and kill manifolds (21–140 MPa, 2″–5″ sizes)	Essential for HPHT well control and flow management operations

3. Built for the Marine Environment — Not Adapted Land Rigs

This is where SJ’s offshore workover specifications differ from most competitors. We don’t take a land rig and bolt it to a skid. Our equipment is purpose-engineered for offshore conditions:

• Corrosion-resistant materials throughout — stainless steel piping and fittings, specialized coating systems for salt spray protection

• Explosion-proof electrical systems — rated Exd II BT5/Exd II BT6 with IP55 protection for hazardous offshore zones

• High wind load capacity — masts designed to withstand typhoon-force conditions with rated wind speeds exceeding 55 m/s (107 knots) for operational safety

• Concentrated utility distribution systems — fuel, freshwater, seawater, compressed air, electrical lines, and fire suppression all integrated into a single elevated distribution system

• Modular skid-mounted design — every module weight optimized for platform crane lift capacities, typically under 15–25 tons per module

• Hydraulic walking systems — lateral and longitudinal movement for cluster well operations without repositioning the entire rig

4. Dual-Purpose Drill-Workover Capability

Our HXJ series offers true drill-workover functionality in a single package. When equipped with a rotary table, swivel, and drilling tools, these units perform as mobile drilling rigs for shallow and medium-depth wells — eliminating the need for a separate drilling rig on your platform.

5. Advanced Hydraulic Workover Technology

SJ’s 2,250 kN hydraulic workover unit incorporates four core technologies: high-efficiency lifting and gripping, high-torque application and transmission, split-type power integration and distribution, and highly adaptive inter-well skidding. The integrated flow control system operates at up to 1,200 L/min and 21 MPa, with adaptive flow and pressure regulation that automatically manages reaction torque during rotary operations.

6. Digital and Automation-Ready Control Systems

SJ offshore workover rigs can be equipped with VFD digital control systems, SCR control with dynamic braking, automatic bit-feeding and integrated instrumentation, and centralized long-distance air control with multiple protection functions. Our control systems are designed for future integration with remote monitoring and predictive maintenance platforms.
