Field Rig Electrical Fault Repair Cases
Case 1: TDS-11SA Top Drive Encoder Failure
KDC Rig23’s TDS-11SA top drive lost position feedback due to a failed digital encoder (P/N 115299). Installing a new OEM encoder restored real-time position monitoring, allowing resumption of safe top drive operation.
Case 2: Baylor 3550HS Brake Firing Board Malfunction
The elmagco brake system failed to engage due to a faulty firing board (P/N 55854). Replacing the PCB firing board fixed the brake control issue, restoring emergency brake functionality and rig safety.Case 3: KEMS Pressure Transducer Signal LossKEMS system lost standpipe pressure data due to a failed 10K psi pressure transducer (P/N 10077045-001). Swapping in a new calibrated transducer restored real-time pressure monitoring, ensuring safe drilling parameters.
