LTSA for LPG Panjang

Overview

The LTSA for the TAS at LPG Panjang is a maintenance service for the facilities and infrastructure of the Terminal Automation System (TAS) at Pertamina IT Panjang Depot LPG Panjang. It keeps the TAS reliable and available. The TAS supports LPG receipt, storage and distribution at the depot.

The scope covers maintenance and troubleshooting of the software, SCADA, TAS hardware and communication equipment, including:

• TAS software: FD-Flow and CSL, which support distribution, receipt and storage.

• SCADA system for process monitoring and control.

• TAS hardware: the TAS server, FD-Flow PC, Weighing House PC and Tapping Card/NFC reader.

• Communication equipment: the communication card and fiber optic.

The LTSA is supported by one standby technician who works office hours. Outside those hours, support runs on an on-call basis. If a TAS fault needs direct handling, the technician comes to site after hours to troubleshoot and fix it (fixing), which limits the impact on operations.

Challenges

• Administration and invoicing still depend on the main contractor, so the time to complete them is affected by coordination with that party.

• Some supporting equipment outside the TAS contract scope developed faults. Because these faults affected TAS operation, the LTSA team had to check and clarify where the problem came from.

• Communication between the weighbridge controller and the Weighing House PC was often lost. This can disrupt weighing and requires troubleshooting of the communication side and the related devices.

• Untidy wiring in the server rack made cable tracing and troubleshooting harder when communication or hardware faults occurred.

Solutions

• Regular coordination and follow-up with the main contractor on administration and invoicing, to speed up completion.

• Root cause identification for every fault, to separate problems that come from the TAS from those in supporting equipment outside the contract scope.

• Checks of the communication path between the weighbridge controller and the Weighing House PC: physical connection, communication card, communication cable and device configuration.

• Evidence-based troubleshooting, with the results of each check documented so problems are handled correctly.

• Tidying and labeling the wiring in the server rack in stages, so cable paths are easier to identify for maintenance and troubleshooting later.

• Using the on-call support system so critical faults outside working hours are handled quickly and operational downtime stays low.

Lessons learned

• On-call support is essential at sites where operations can run outside working hours, especially when a TAS fault directly affects operations.

• Communication faults in the weighing system show the need for regular maintenance and monitoring of communication paths.

• Tidy, documented wiring speeds up tracing and troubleshooting and lowers the risk of mistakes during maintenance.

• Every fault should be analyzed through root cause and evidence, so a problem in equipment outside the TAS scope is not assumed to be a TAS fault.

• Good coordination with the main contractor and Pertamina keeps administration moving and lets technical work proceed effectively.
