2. Functional Instructions
- 10068347-001 15’’ Touchscreen Panel Base: Serves as the main human-machine interface (HMI) for the NOV TDS top drive, allowing operators to monitor real-time electrical parameters (voltage, current, signal status) and issue control commands. It features a high-resolution display (1024×768) and a response time of ≤50ms, ensuring smooth operation.
- 10663569-001 Barracuda 19” Gen 2 SA Workstation HMI: Provides advanced control and monitoring capabilities, supporting multi-task operation and data logging. It has a 16GB storage capacity and is compatible with NOV’s proprietary control software, enabling remote diagnostics.
3. Structural Characteristics
All NOV TDS electrical parts are manufactured using high-quality, industrial-grade materials to withstand the harsh conditions of oil and gas drilling: Control components (touchscreen panel, HMI, joysticks) use flame-retardant ABS plastic (UL94 V-0 rating) and scratch-resistant glass for the touchscreen, ensuring durability and resistance to fire and impact. PLC modules and power supply components use oxygen-free copper conductors (conductivity ≥99%) and industrial-grade semiconductors (silicon carbide for IGBTs), providing high efficiency and stability.
4. Applicable Working Conditions
The NOV TDS electrical parts are engineered to perform reliably in the harsh, demanding working conditions of onshore and offshore oil and gas drilling, with specific applicability tailored to the NOV TDS top drive’s operational requirements:
- Temperature Range: -40℃ to 85℃, suitable for extreme cold (onshore winter drilling) and high-temperature (offshore summer, engine room) environments, ensuring electrical performance remains stable without overheating or freezing.
- Voltage & Current Range: Compatible with 120/230/480VAC input voltage and 24VDC control voltage, with current ratings ranging from 1A to 60A, matching the NOV TDS top drive’s electrical system specifications.
5. Maintenance and Maintenance Suggestions
To extend the service life of NOV TDS electrical parts and ensure the safe, stable operation of the top drive’s electrical system, the following practical maintenance suggestions are provided (based on NOV OEM guidelines and on-site drilling maintenance experience):
- Regular Inspection: Conduct a comprehensive inspection of electrical parts every 150 working hours (drilling operation) or 300 working hours (standby). Focus on checking power supply components (voltage output, temperature), PLC modules (signal status, error codes), connectors (loose contacts, corrosion), and sensing components (measurement accuracy, waterproof seals). For offshore operations, increase inspection frequency to every 100 working hours due to harsher environmental conditions.
- Cleaning and Dust Removal: After each drilling shift, clean the surface of control components (touchscreen, HMI, joysticks) with a dry, lint-free cloth to remove dust and drilling mud. Use compressed air to blow dust from PLC modules, circuit breakers, and fans, ensuring proper heat dissipation. Avoid using water or chemical cleaners, as they may damage electrical components.

6. On-Site Fault Maintenance Cases
Case 1: NOV TDS HMI Malfunction Caused by Faulty Touchscreen Panel Base
Scenario: An NOV TDS top drive on an offshore drilling rig experienced unresponsive HMI operation, with the touchscreen failing to register commands. Inspection found that the 10068347-001 15’’ touchscreen panel base had internal circuit damage due to water ingress (caused by a damaged waterproof seal), leading to signal loss.
Solution: Replace the faulty 10068347-001 touchscreen panel base with a new OEM part, replace the waterproof seal, and test the HMI’s responsiveness. After maintenance, the touchscreen responded normally (response time ≤50ms), and the HMI resumed full control functionality, avoiding further drilling downtime.
Case 2: PLC Signal Loss Caused by Damaged PROFIBUS Connector
Scenario: A NOV TDS top drive on an onshore drilling rig experienced intermittent PLC signal loss, leading to unstable top drive operation (speed fluctuations, unresponsive controls). Inspection found that the 10042793-001 PROFIBUS DP connector had corroded contacts due to dust and moisture, disrupting signal transmission.
Solution: Replace the damaged 10042793-001 PROFIBUS connector with a new OEM part, clean the PLC module’s connection port, and secure the connector to ensure a tight fit. After replacement, the PLC signal transmission was stable (data rate 12 Mbps), and the top drive resumed normal operation, eliminating signal loss issues.
Case 3: Power Supply Failure Caused by Faulty Redundant Power Module
Scenario: An NOV TDS top drive experienced a sudden power failure, shutting down the electrical system. Inspection found that the 10066946-001 40A redundant power supply module had failed (one of the two redundant units malfunctioned), and the backup unit did not activate due to a faulty internal switch.
Solution: Replace the faulty 10066946-001 redundant power supply module with a new OEM part, test the backup functionality to ensure it activates automatically in case of primary unit failure, and check the power supply voltage output (24VDC ±1%). After maintenance, the power supply system was restored, and the top drive resumed normal operation, preventing future unplanned power failures.
7. FAQ (Frequently Asked Questions)
| No. | Questions | Answers |
| 1 | Are these OEM electrical parts fully compatible with all NOV TDS top drive models? | Yes, all parts in this list are 100% OEM-manufactured by NOV, specifically designed to be compatible with all NOV TDS top drive models. Each part matches the original specifications, including voltage, current, dimensions, and communication protocols (PROFIBUS, Ethernet), ensuring seamless installation and stable performance. We strictly follow API 7K, IEC 60947, and ISO 9001 standards, eliminating the risk of mismatched parts and electrical system malfunctions. |
| 2 | What is the difference between the 10066946-001 (40A) and 10044673-001 (20A) redundant power supply modules, and how to choose the right one? | The key difference is the current rating: the 10066946-001 is a 40A redundant power supply module, suitable for powering high-load electrical components (e.g., HMI workstations, multiple PLC modules), while the 10044673-001 is a 20A module, designed for low-load systems (e.g., small control panels, single PLC modules). To choose the right one, check the total current consumption of your NOV TDS top drive’s electrical system: if the total current is ≤20A, use the 10044673-001; if it exceeds 20A (up to 40A), use the 10066946-001. Always refer to the NOV TDS maintenance manual for specific current requirements. |
| 3 | How to quickly confirm the correct part number when purchasing NOV TDS electrical parts for emergency drilling maintenance? | You can use three simple methods to confirm: 1) Check the original NOV TDS top drive maintenance manual, which lists the part number for each electrical component; 2) Remove the faulty part and check the NOV part number marked on its surface (all OEM parts have clear, permanent marking); 3) Provide the NOV TDS model, the faulty component’s description (e.g., 15’’ touchscreen panel base, 4-channel digital input module), and the drilling rig’s operation type (onshore/offshore) to our technical team, and we will accurately match the corresponding part number. This list covers 60 common electrical parts, meeting most emergency maintenance needs during drilling operations. |
