System degradation eventually leads to unexpected faulty conditions or even downtime. We provide control system maintenance and troubleshooting as a proactive and reactive reactive measures for coping with these situations and ensuring continuous operation.
Control loops tuned at commissioning degrade over time: process conditions change, equipment wears, and setpoints drift. We provide periodic or continuous loop performance monitoring, identifying loops that are oscillating, saturating, or underperforming, with a prioritised report of recommended actions.
Control system documentation that does not reflect the current state of the plant is a maintenance and safety liability. We audit and update as-built logic drawings, I/O lists, functional descriptions, and software version records — producing accurate documentation that supports fault diagnosis, regulatory compliance, and future upgrade work.
New equipment, modified processes, and changing regulatory requirements all place demands on existing control systems. We manage upgrades and expansions — from software updates and hardware replacements to adding new plant sections or integrating new systems — planned, tested, and documented to the same standard as a new installation.
