Routine inspection of building structures and surrounding areas, including the maintenance and repair of confinement doors. Conduct repairs and installations of electrical motors, pumps, valves, or equipment and ensure proper alignment. Installation and inspection of strainers, including Primary conical strainer.

Conduct initial testing and adjustments to ensure new installations are functioning correctly and meet operational standards. Conduct an investigation analysis report to determine the root cause, contributing factors and corrective actions needed to prevent recurrences on mechanical engineering systems.
