Description
3000-9000m Offshore Drilling Rig
AC VFD Offshore Drilling Rig for Deep Oil & Gas Wells, Fixed Platforms, and Jack-Up Drilling Projects
SGPE 3000-9000m Offshore Drilling Rig is designed for deep oil and gas wells that require stable hoisting, compact deck arrangement, digital control, and long-term reliability in harsh marine environments. It supports exploration wells, development wells, appraisal wells, directional wells, extended-reach wells, deep reservoir drilling, and platform-based well construction.
This offshore rig fits fixed platforms, jack-up platforms, modular drilling packages, and customized marine oilfield projects. With a drilling depth range from 3000m to 9000m, it gives offshore operators a flexible solution for medium-depth and deep-well drilling programs.
SGPE equips the rig with an electric-driven AC variable frequency drive system, a fully digital control scheme, modular rig packages, and offshore-grade components. This configuration helps drilling contractors, oil companies, EPC contractors, platform owners, and oilfield service companies reduce deck space demand, simplify installation, and improve drilling efficiency during long operating cycles.
Product Overview
The SGPE 3000-9000m Offshore Drilling Rig uses two or more AC variable frequency motors to drive the drawworks. An auto-feeding motor improves bit feeding control and helps operators maintain smoother drilling performance.
The rotary table uses an independent AC VFD motor. The mud pump system can adopt one or two AC variable frequency motors according to the well program, mud circulation demand, and platform power supply conditions.
The fully digital control system gives operators accurate speed regulation, stable torque output, smooth hoisting control, and reliable drilling parameter management. As a result, drilling crews can handle tripping, casing running, drill string handling, directional drilling, and deep-well operations with better control and lower mechanical impact.
SGPE applies modular design to the rig floor, drawworks, mast, substructure, mud pump system, solids control system, and auxiliary system. This structure reduces offshore assembly work, shortens installation time, improves lifting efficiency, and simplifies later inspection and maintenance.

This rig suits operators who need reliable hoisting, stable mud circulation support, compact deck arrangement, corrosion-resistant equipment, and digital operation control for long-term offshore service.
AC VFD Electric Drive System
The electric-driven offshore rig uses an AC variable frequency drive system to control key drilling equipment. Compared with traditional mechanical drive systems, the AC VFD system provides smoother speed adjustment, more accurate torque control, lower mechanical shock, and better energy efficiency.
Two or more AC variable frequency motors drive the drawworks and support stable hoisting during drilling, tripping, casing running, and heavy-load handling. The auto-feeding motor helps operators control bit feed rate more accurately during deep-well operations.
The rotary table uses a separate AC VFD motor, so operators can adjust rotary speed according to formation condition, well trajectory, drill string load, and drilling tool requirements. The mud pump system can use one or two AC VFD motors to match different flow rate and pressure demands.
This digital drive and control scheme helps the rig deliver consistent performance during long offshore drilling cycles and complex well construction.
Compact Layout for Limited Platform Space
Offshore platforms often face strict limits on deck space, deck load, lifting route, and equipment arrangement. SGPE optimizes the rig structure to reduce footprint and improve platform space utilization.
The compact layout helps platform owners reduce deck load planning pressure, arrange equipment more efficiently, and simplify installation. It also supports easier transportation, lifting, inspection, and maintenance.
For marine oilfield projects, a compact rig layout improves project execution. It reduces unnecessary installation work and helps crews complete rig-up within limited offshore operation windows.
Modular Design for Faster Offshore Installation
SGPE applies modular design to the main rig systems, including:
- Rig floor
- Drawworks
- Mast
- Substructure
- Mud pump system
- Solids control system
- Auxiliary system
This modular structure helps users transport, lift, install, inspect, and maintain the rig more efficiently. It also helps EPC contractors and platform builders plan the drilling package according to deck space, crane capacity, lifting route, module size, project schedule, and classification society requirements.
For projects with tight installation windows, modularization reduces offshore assembly workload, improves installation flexibility, and supports faster project delivery.
Reliable Drawworks and Brake System
The rig uses single drum drawworks for hoisting operations. The main brake adopts an energy-consumption brake, while the auxiliary brake adopts a hydraulic disc brake.
This braking configuration supports stable hoisting, smooth speed control, and reliable braking during tripping, drilling, casing running, drill string handling, and heavy-load operations.
The drawworks design improves operating control and reduces mechanical impact during frequent drilling cycles.
Derrick Options for Platform-Based Drilling
SGPE can configure the derrick as a tower-type mast or a multi-section self-elevating derrick according to platform requirements.
The tower-type mast provides strong structural stability and suits long-term offshore well construction. The multi-section self-elevating derrick improves transportation and assembly convenience, especially for modular offshore drilling packages.
Both derrick options help the rig adapt to different platform layouts, lifting conditions, drilling depths, and field operation programs.
Drill Floor Options
SGPE provides two drill floor structure options for different platform layouts.
| Drill Floor Type | Main Advantages | Suitable Applications |
|---|---|---|
| Frame-type structure | Strong overall structural performance and light weight | Offshore platforms requiring high structural integrity and stable working space |
| Small modular structure | Easier transportation, lifting, and platform assembly | Modular drilling packages and platforms with limited lifting capacity |
The frame-type drill floor suits projects that require stronger structural integrity and reduced overall weight. The small modular drill floor suits platforms that need smaller lifting modules, easier transportation, and faster assembly.
SGPE can recommend a suitable drill floor design according to deck space, crane capacity, rig layout, drilling depth, and operation requirements.
