Objective

To monitor, evaluate and optimise performance and ensure the CO₂ entering and exiting the system adheres to the required product specification for inlet and outlet of transport system.

Major Deliverables

• Performance reviews
• Test results
• Benchmarking studies
• Storage system requirements reviews
• Regulatory compliance assessments
• EH&S reviews
• Modified designs, systems and procedures

Tasks

Note operation of pipeline covered in operations. Specific tasks include the following:

• Measure performance and benchmark against own objectives and competitors performance.
• Regularly review legal and statutory requirements including environmental standards emissions standards and performance standards.
• Regularly review storage system requirements to ensure alignmemt,
• Regularly review Best Practices and Best Available Technologies
• Regularly assess and identify opportunities for improvement
• Monitor CO₂ entering, during and leaving pipeline and adjust operation to ensure that CO₂ falls within specifications.  This may be performed wholly or partly using an automated control system
• Follow approved operating and safety procedures to ensure that out of specification CO₂ is prevented from entering the system by e.g. safely venting contaminated CO₂, increasing or reducing flow rates to respond to changes in temperature, pressure or quantity, shutting down system if required, etc
• If an instance of out of specification CO₂ results in a potential health and safety risk, the appropriate operating procedure (e.g. shutdown) should be followed.  Conduct an incident investigation and address the cause of the incident and any impacts prior to restarting the system
• If an instance or series of occurrences of out of specification CO₂ results in any other substantial impact e.g. significant loss of operating time or income, large quantity or frequent amounts of CO₂ being vented etc., conduct an incident investigation and address the cause of the incident(s) and any impacts
• Regularly review outputs of monitoring, metering and verification (MMV) equipment and consider if any changes to operating procedures and/or systems/equipment  are required. This should include:
• Assess severity of impact of any out of specification CO₂including consideration of cumulative effects.  This should consider:
  • Magnitude of each individual instance
  • Cumulative effect of all incidents from installation / last major maintenance considering cycles such as startup/shutdown, pressure cycling, thermal cycling, wet/dry CO₂ cycling etc
  • Results of condition monitoring of pipeline and equipment
  • Possibility of any impact on pipeline structural integrity or equipment condition of previous or future incidents, considering the possibility of crack propagation, ductile and brittle fracture, cavitation, creep, thermal fatigue etc
• Identify any requirements for replacement, upgrade or more frequent maintenance of pipeline sections and associated infrastructure and equipment;
• Review operating procedures and assess whether improvements could be made;
• Review existing monitoring, metering and verification (MMV) equipment, consider any new equipment available and assess whether improvements to MMV equipment are required; and
• Review existing control equipment including SCADA (secure control and data acquisition), consider any new equipment available, and assess whether improvements to control equipment are required
• Implement any required changes to operational procedures:
• To ensure the reliability of the CO₂ flow meets the required specification
• To ensure the quality of CO₂ meets specification and/or additional conditioning required is carried out
• To respond to changes in composition, pressure, temperature or flow rate of CO₂
• For startup/shutdown of pipeline and associated infrastructure
• For linepacking of pipeline
• For control and instrumentation communication requirements so CO₂ monitoring by all parties is possible to the degree required
• Inspection schedules taking into account possible variability in CO₂ production rates
• Monitoring required to ensure that thermal fatigue is identified before it poses a health and safety risk etc
• Update all affected documentation to as built status including
• Piping and instrumentation diagrams (P&ID)s
• Datasheets
• Buried services
• Operating and maintenance manuals and procedures
• Asset Register
