Calculation of minimum installation availability

Calculation of minimum installation availability

Branche: Oil & Gas

The project began with an investigation into the minimum availability and limitations of the system under exceptional circumstances. The goal was to increase the availability of the control system and reduce system dependencies. This led to the recommendation to technically and physically split the system across multiple locations. Autonomous control was then implemented so that the systems could function independently. In addition, an emergency control panel was developed for manual pump operation outside the regular control and safety system. Finally, the new systems were commissioned, the old system was dismantled, and the safety philosophy was revised.

Project description

Tebulo Engineering conducted a comprehensive study on the availability of its systems. First, an inventory of all systems was made and the underlying principles were determined. Next, scenarios that could impact availability were analyzed, categorized into E-power supplies, control & automation, system safety, and piping.

An FMEA was prepared for each component to identify potential failures and their consequences. After analyzing the current and desired situation, an inventory of potential solutions was created. This resulted in a recommendation for a technical and physical separation of the control system across the three main locations.

This included a hardware upgrade, a revision of the communications network, and enhanced cybersecurity. In addition, an autonomous emergency control system was developed that allows the pumps to be manually operated in the event of a failure of the regular control system. This guarantees minimum capacity, even in the event of a complete system failure. A full-fledged control option was also implemented at Site 1, allowing operations to continue if Site 2 fails.

By implementing autonomous systems, functional separation of processes, and enhanced security, the system's availability has been significantly increased. This prevents complete downtime in the event of a malfunction and provides greater flexibility for maintenance work without operational interruptions.
