The TAS supports LPG receipt, storage and distribution. | Field | Value | | --- | --- | | Year | 2022 | | Status | Finished | | Updated | 2026-08-10 | ## About this work ### 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. ## Contact - Company: PT Citia Engineering Indonesia - Email: services@citiaengineering.com - Telephone: +62 21 278 20286 - Office: Jl.
