We produce modular offshore drilling rigs, such as the HY70DB and HY90DB series, designed to withstand demanding marine environments and platform space limitations. Key components like the crown block, derrick, and drawworks are manufactured to meet rigorous domestic and international standards, ensuring reliable performance for offshore drilling operations.
The rig's core structure features the crown block, derrick, substructure, and drawworks. The derrick's main components are hot-dip galvanized to maximize corrosion resistance. Designed specifically for offshore platforms, this rig reliably meets the demanding requirements of marine drilling operations.
The crown block consists of the platform, sheave assemblies, and accessories. Each sheave bearing has an independent lubrication channel, and all points are centralized on the platform for easy access. A centralized automatic lubrication system is also included to streamline maintenance and servicing.
The rig utilizes a bottleneck-type tower derrick with a detachable, bolted, enclosed steel structure and a square cross-section. This configuration provides exceptional stability, safety, and reliability.
Featuring AC variable-frequency control, this single-shaft gear-driven drawworks consists of AC motors, a gearbox, hydraulic disc brakes, a drum shaft, and an automatic driller. The system employs motor regenerative braking as the primary brake and a hydraulic disc brake as the auxiliary brake.
The rig floor includes a drainage system to prevent the buildup of mud, oil, and sewage. The substructure bottom is fully enclosed and features a waste liquid recovery system to meet strict environmental requirements.
Crown block sheave bearings feature independent channels and a centralized automatic lubrication device.
Derrick structural components are hot-dip galvanized to withstand salt spray and high humidity.
High-reliability AC variable-frequency motors and advanced control systems power the drawworks and mud pumps for deepwater operations.
Features a rig floor drainage system and a fully enclosed substructure base with waste liquid recovery.
Equipped with large-scale CNC gantry mills, machining centers, and Lebus groove lathes to meet all drilling rig component production needs.
HY70 and HY90 series rigs have operated safely and reliably with Sinopec Offshore Drilling Company for years, proving our mature technology.
A strong domestic and international support network ensures full product protection throughout its lifecycle.
