Core Responsibilities

Primary Functions

Continuously monitor and interpret readings from control panels, gauges, and Distributed Control System (DCS) screens to regulate temperature, pressure, flow rates, and fluid levels within processing units.
Perform routine operational adjustments to valves, pumps, compressors, and other equipment to ensure processes remain within specified operating parameters and meet production targets.
Conduct thorough field inspections and rounds, visually checking equipment for leaks, unusual noises, vibrations, or other signs of malfunction to proactively identify potential issues.
Draw samples of various process streams and products at designated intervals for laboratory analysis, ensuring strict adherence to sampling procedures to maintain quality control.
Execute established startup, shutdown, and emergency shutdown procedures for individual pieces of equipment and entire processing units with a high degree of precision and safety.
Utilize and follow complex operating procedures, Piping and Instrumentation Diagrams (P&IDs), and process flow diagrams to understand and manage process operations.
Isolate and prepare equipment for maintenance activities by performing Lockout/Tagout (LOTO), blinding, and clearing procedures to ensure a zero-energy state for safe work.
Issue and oversee safe work permits for maintenance and contractor activities, verifying that all safety precautions and prerequisites have been met before work commences.
Respond effectively to alarms and process deviations, applying systematic troubleshooting techniques to diagnose the root cause and take appropriate corrective action to restore stable operation.
Maintain detailed and accurate operational logs, shift reports, and data sheets, clearly documenting process conditions, changes made, and any unusual events for continuity of operations.
Collaborate closely with control room operators, maintenance personnel, laboratory technicians, and shift supervisors to coordinate activities and ensure seamless communication.
Participate actively in safety programs, daily safety meetings, and hazard identification processes to contribute to a culture of zero incidents.
Perform minor-to-intermediate maintenance tasks, such as lubricating equipment, tightening connections, replacing filters, and cleaning strainers to support equipment reliability.
Operate heavy machinery such as forklifts, aerial lifts, or other mobile equipment as required for operational tasks, maintaining all necessary certifications.
Monitor and manage utility systems integral to the process, including steam, cooling water, instrument air, and nitrogen systems.
Act as a first responder for operational emergencies, such as fires or chemical releases, taking initial steps to mitigate the situation according to established emergency response plans.
Ensure strict compliance with all environmental regulations, including monitoring emissions, managing waste streams, and reporting any environmental exceedances.
Transfer finished products and intermediate feedstocks between tanks and to/from pipelines, trucks, or railcars, ensuring accurate measurements and safe handling.
Contribute to the Management of Change (MOC) process by reviewing proposed changes to procedures or equipment and providing operational input.
Mentor and provide on-the-job training for new or less experienced operators, sharing knowledge of plant operations, safety procedures, and best practices.
Utilize computer-based maintenance management systems (CMMS) to write work orders for equipment repairs and track the status of ongoing maintenance jobs.
Participate in unit performance testing and optimization initiatives, collecting data and providing operational support to engineering teams.

Secondary Functions

Participate actively in safety committee meetings and formal incident investigation teams to help determine root causes and recommend corrective actions.
Assist in the development, review, and updating of standard operating procedures (SOPs) and emergency response guidelines.
Support shutdown (turnaround) planning and execution by assisting with equipment lists, isolation plans, and post-maintenance recommissioning.
Act as a subject matter expert during Process Hazard Analyses (PHAs) and other risk assessment activities.
