What regulations apply to compressor station inspections in Australia?

Compressor station inspections in Australia are governed by multiple regulatory frameworks. AS 2885 (Pipelines - Gas and Liquid Petroleum) covers pipeline and compressor station design, construction, operation and maintenance requirements. AS 1210 and AS 3788 apply to pressure vessels and pressure equipment in-service inspection. State and territory petroleum pipeline safety regulations impose specific obligations for safety management, inspection programmes and incident reporting. The NGER Act 2007 requires facilities above certain emission thresholds to report greenhouse gas emissions, which drives fugitive emissions monitoring requirements. WHS legislation requires that the facility is maintained in a safe condition for workers and visitors.

How often should a compressor station be inspected?

Daily operator rounds should check basic operating parameters, visible leaks and unusual noises. Monthly comprehensive inspections should cover all compressor units, piping, vessels, electrical systems and facility condition. Quarterly inspections should include safety system function testing (ESD, gas detection, fire systems). Vibration analysis and oil sampling should follow the condition monitoring programme (typically monthly). Fugitive emissions surveys should be conducted at the frequency required by the environmental licence. After any compressor trip, gas release or safety incident, a targeted inspection should be performed immediately.

What is the difference between a reciprocating and centrifugal compressor inspection?

Reciprocating compressor inspections focus on piston and cylinder condition, valve plate wear and leakage, packing seal condition (monitored via packing vent gas flow), crosshead and connecting rod bearing condition, lubricating oil quality and pulsation dampener function. Centrifugal compressor inspections focus on impeller and diffuser condition, shaft seal systems (dry gas seals or oil seals), bearing condition and vibration analysis, lube oil and seal oil system performance, and surge protection system function. Both types require operating parameter monitoring (pressures, temperatures, vibration) but the wear patterns and failure modes differ significantly, requiring type-specific inspection knowledge.

Why is fugitive emissions monitoring important at compressor stations?

Compressor stations handle large volumes of natural gas (primarily methane, a potent greenhouse gas) under high pressure, creating numerous potential leak points at flanges, valves, seals, connectors and instrument fittings. Fugitive emissions from these sources contribute to greenhouse gas emissions and may create localised safety hazards. Australian environmental regulations and the NGER Act require facilities to monitor and report emissions. Leak detection and repair (LDAR) programmes using optical gas imaging cameras, gas sniffers or soap bubble testing systematically identify and quantify leaks for repair. Regular fugitive emissions surveys during inspections reduce the facility environmental footprint and demonstrate regulatory compliance.

What is a compressor station inspection checklist?

A compressor station inspection checklist is a structured document used to assess the operational condition, safety compliance and environmental performance of a gas compressor station. Compressor stations are critical infrastructure in natural gas transmission and distribution pipelines, gas processing plants and gas storage facilities, providing the pressure boost required to move gas through the pipeline network. The checklist covers reciprocating or centrifugal compressor units (mechanical condition, vibration levels, temperature readings, oil analysis), prime mover or driver inspection (gas engine, electric motor, gas turbine), process piping and vessel condition, pressure relief and safety shutdown systems, gas detection and fire protection systems, emissions monitoring and leak detection, electrical and control systems, facility security and housekeeping, and regulatory documentation.

Compressor stations operate under high pressures and temperatures with flammable gas, making them inherently high-risk facilities. Equipment failures can result in gas releases, fires, explosions and environmental incidents. Compressor components are subject to continuous mechanical stress, vibration, thermal cycling and corrosive gas constituents that cause progressive wear and degradation. Process safety management principles require regular documented inspections to identify deterioration before it leads to loss of containment. Pipeline regulations in Australia and internationally mandate that compressor station operators maintain inspection and maintenance programmes that ensure the station remains safe, reliable and environmentally compliant. A standardised inspection checklist provides the framework for systematically evaluating every aspect of the station, from individual compressor components to facility-wide safety systems, in a repeatable and auditable manner.

Benefits of using this compressor station inspection checklist

Process safety: systematic inspection of compressors, piping, vessels and safety systems identifies degradation, leaks and potential failure modes before they result in loss of containment, fires or explosions.
Operational reliability: detecting vibration changes, temperature anomalies, oil contamination and seal wear early prevents unplanned compressor shutdowns that disrupt gas supply to downstream customers.
Emissions compliance: inspecting for gas leaks, verifying emissions monitoring equipment and checking flare or vent systems ensures compliance with environmental regulations and licence conditions.
Regulatory compliance: documented inspection records demonstrate compliance with pipeline safety regulations, dangerous goods requirements and workplace health and safety obligations.
Equipment longevity: proactive maintenance driven by inspection findings extends the service life of compressor units, drivers and auxiliary equipment, reducing capital replacement costs.
Safety culture: regular structured inspections reinforce the importance of process safety management across the operations team and provide opportunities to identify emerging hazards.

What to include in a compressor station inspection checklist

This compressor station inspection checklist covers 9 key areas:

Compressor units: check compressor vibration levels against baseline, record discharge and suction temperatures and pressures, inspect packing and seals for gas leaks, check oil level and condition (reciprocating) or lube oil and seal oil systems (centrifugal), inspect valves (reciprocating) or impeller condition (centrifugal).
Prime movers: gas engine inspection (oil level, coolant, ignition system, exhaust emissions), electric motor checks (winding temperature, insulation resistance, bearing condition), gas turbine inspection (inlet filters, combustion inspection ports, exhaust temperature spread).
Process piping: visual inspection of all station piping for corrosion, vibration fatigue cracking, support condition, flange leaks, and insulation damage, check all valves for correct position and operability.
Pressure vessels: inspect scrubbers, separators, coolers and pulsation dampeners for corrosion, mechanical damage, pressure relief valve condition and instrument connections.
Safety shutdown system: test emergency shutdown (ESD) system function, verify high-pressure, low-pressure and high-temperature shutdown set points, test station blow-down valves.
Gas detection and fire protection: test gas detectors (catalytic bead and infrared), test fire detection system (heat, flame, smoke), inspect fire suppression equipment (extinguishers, deluge, foam), verify alarm communication to control room.
Emissions and environment: conduct fugitive emissions survey using approved leak detection method (OGI camera, soap bubble, gas sniffer), check flare or vent system operation, inspect spill containment and waste management.
Electrical and control: inspect switchgear, motor control centres, transformers, UPS and battery systems, verify SCADA communication, check control panel instruments and annunciators.
Facility and security: inspect station fencing, signage, access roads, lighting, stormwater drainage and vegetation management, verify emergency response equipment is accessible and current.

How to use this compressor station inspection checklist

Review the station operating data, alarm history, previous inspection reports and any outstanding work orders before arriving at the station.: Access the station SCADA data to review operating pressures, temperatures, vibration trends and any recent alarms or shutdowns. Review the previous inspection report for outstanding corrective actions. Check the maintenance management system for open work orders. Note any recent operational changes such as throughput increases, new gas compositions or equipment modifications that may affect the inspection focus.
Conduct a walk-around inspection of the entire station: check compressor units, piping, vessels, safety equipment, electrical systems and facility condition.: Walk the entire station perimeter and all internal areas. Inspect each compressor unit for unusual vibration (use a handheld vibration meter if available), abnormal noise, visible leaks, oil seepage and temperature anomalies (use an infrared thermometer on bearings, cylinders and discharge piping). Inspect all process piping for corrosion, support damage, flange leaks and insulation deterioration. Check all pressure vessels for external corrosion, relief valve condition and drain valve position. Inspect electrical equipment for damage, overheating signs and correct labelling. Check facility fencing, signage, lighting and access roads.
Record compressor operating parameters: suction and discharge pressures and temperatures, vibration readings, oil levels and condition, seal or packing condition and any abnormal observations.: At each compressor unit, record suction pressure, discharge pressure, suction temperature, discharge temperature and flow rate from local gauges and compare against the normal operating envelope. Take vibration readings at designated measurement points (typically bearing housings in three axes) and compare against baseline values and alarm thresholds. Check oil levels on all lubrication systems. Take an oil sample if the sampling schedule requires it. For reciprocating compressors, check packing vent lines for excessive gas leakage. For centrifugal compressors, check seal oil differential pressure and return flows.
Test safety systems: perform a function test of the emergency shutdown system, verify gas detector calibration dates, test fire detection system and inspect fire suppression equipment.: Coordinate with the control room before testing safety systems. Perform a function test of the ESD system by activating the manual ESD button or simulating a high-pressure trip, and verify the correct shutdown sequence occurs (compressor trips, blow-down valves open, station isolation valves close). Verify gas detector calibration is current (typically calibrated every 3 to 6 months). Test fire detection elements (heat, flame, smoke) and verify alarms annunciate at the control room. Inspect all fire extinguishers, deluge nozzles and foam systems for condition and serviceability.
Conduct a fugitive emissions survey, inspect environmental controls and check compliance documentation. Complete the inspection report with all findings and corrective actions.: Conduct a fugitive emissions survey using an approved method such as an optical gas imaging (OGI) camera, soap bubble testing on flanges and connections, or a handheld gas sniffer. Record all detected leaks with their location, estimated leak rate and required repair action. Inspect the flare or vent system for correct operation. Check spill containment around lube oil and chemical storage areas. Verify that all regulatory permits, inspection certificates and emergency response plans are current and accessible. Complete the inspection report documenting all findings with photographs, measurements and severity ratings. Create corrective actions for all defects and assign responsibility and due dates.

How often should you complete this checklist?

Compressor stations should receive a comprehensive inspection at least monthly, with daily operator rounds covering basic checks (operating parameters, visible leaks, unusual noises). Major inspections including safety system function testing should be performed at least quarterly. Compressor vibration analysis and oil sampling should be performed monthly or according to the condition monitoring programme. Gas detector calibration should be performed every 3 to 6 months per the manufacturer recommendation.

Fugitive emissions surveys should be conducted at the frequency required by the facility environmental licence (typically quarterly or annually). After any compressor trip, station shutdown, gas release or safety incident, a targeted inspection should be performed before the station returns to normal operation. Pipeline regulations may impose additional inspection requirements. In MapTrack, configure calendar-based triggers for monthly comprehensive inspections and quarterly safety system tests, and event-based triggers for post-incident inspections.
