Key Pain Points Solved
- Drilling Efficiency Loss: A single ATB control failure can cause 3-6 hours of shutdown, resulting in a direct loss of over $25,000 per day for drilling operations due to interrupted tubular supply.
- Safety Compliance Risks: Damaged ESD relays, emergency stop buttons or safety barriers fail to meet API RP 541 and IEC 61508 safety standards, leading to potential safety hazards and regulatory non-compliance.
- System Matching Problems: Non-standard spare parts cause incompatibility with Siemens PLC system (CPU1215C, SM1222, SM1231, SM1232), resulting in signal transmission errors and cylinder displacement deviation.
- Short Service Life of Inferior Parts: Low-quality solenoid valves, sensors and power supplies fail frequently under high vibration and dust environment, increasing maintenance frequency and cost.

On-Site Fault Repair Cases
Case 1: ATB Lifting Failure Caused by Damaged Motor Encoder
An onshore drilling rig’s ZGH127-1500T ATB failed to lift tubulars normally, with position deviation and abnormal alarm. After inspection, the internal winding of the raising motor encoder was damaged, resulting in no position signal feedback. Replacing the dedicated raising motor encoder restored normal lifting action and position accuracy, and the equipment resumed operation within 1.5 hours.
Case 2: PLC Communication Fault Due to Failed Profibus DP-Master
The control panel of ZGH127-1500T ATB could not receive equipment status signals, and the automatic mode was unavailable. Testing showed that the CM1243-5 Profibus DP-Master module was damaged, leading to communication interruption. After replacing the Siemens original Profibus DP-Master module, the communication was restored, and the automatic control function of ATB was normal.
Case 3: Emergency Shutdown Failure Caused by Faulty ESD Relay
During a routine safety inspection, the emergency stop function of ATB failed, which could not trigger the system shutdown. The fault was located in the PSR-ESAM4 ESD relay with internal contact burnout. Replacing the special ESD relay made the emergency stop system work normally, meeting the oilfield safety inspection requirements.
