CO2 Product for Power Capture in the Operate stage
- Monitor and evaluate performance
- Optimise the asset
- Identify and implement new value creating opportunities
- Modify the compression plant as appropriate to comply with legislative changes and best available techniques (BAT).
- Performance reviews
- Test results
- Benchmarking studies
- Regular market review
- Legislative reviews
- EH&S reviews
- Updated designs and operating procedures for compression and dehydration plant
Note operation and maintenance of the capture and compression plant is covered in [link to operations page].
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 market demand, feed stocks, product specifications, supply and services arrangements.,
- Regularly review Best Practices and Best Available Technologies
- Regularly assess and identify opportunities for improvement
- For each identified potential change assess
- Driver for change i.e. regulatory, EH&S, risk reduction, profit improvement
- Extent / cost / benefit and risk of the change including downtime.
- Complexity and level of risk associated with the change especially in relation to other affected systems or parties
- Length of time over which change will be effective.
- cost for non-mandatory potential changes, considering costs and benefits over the remaining lifetime of the plant and
- Compare with other potential changes and
- Decide on whether to implement change
- Determine whether a full gated project development and implementation process is warranted. In which case the Identify, Evaluate, Define and Execute processes should be followed making due allowance that the change is now occurring within an operating brown fields environment.
- Specific tasks for modification to operating plant in a brown fields environment should include:-
- Produce specification documents for change
- Produce design philosophy documents for change
- Assess impacts to all affected plant, utilities, systems and stakeholders
- Interact with affected stakeholders and ensure that changes are understood and endorsed.
- Develop construction procedures and safe work practices and perform job safety analysis prior to commencing any work on or near operating plant.
- Produce plans and procedures for pre-commissioning, commissioning,
- Update redundancy philosophy and design of associated systems and/or equipment
- Assess electrical systems and utilities to ensure that adequate capacity exists especially if additional large rotating machinery and or cooling loads are introduced.
- Review impacts and update design of the plant control system and safety instrumented systems
- Update design of condition monitoring systems for new or modified rotating machinery such as the compression plant and equipment
- Prior to placing the changes into operation perform installation checks, mechanical and electrical checks and pressure tests.
- Inspection and testing of each new individual component of a subsystem prior to placing the subsystem into service
- Static tests to demonstrate interactive operation of components prior to charging or energizing the system for the first time
- Inspection and testing of each new or changed sub-system prior to placing the system into service
- Flushing of equipment and pipe work
- Proving the integrity of all connections (mechanical and electrical)
- Proving the integrity of all safety and emergency response systems such pressure relief valves and fire detection and protection
- Verification that all plant is functionally complete
- Verification of and checking of all protection settings
- Checking of plant inter-tripping circuits
- Cold (pre-) commissioning, i.e. electrical and control systems are energised, checked and tested to the extent possible, rotation checks are carried out on pumps etc instruments and control loops especially trip circuits tested to the extent possible
- Hot commissioning i.e. materials and utilities are introduced into the modified plant, systems cut-over and integrated operation is confirmed.
- Ramp-up operation and run performance tests on changed plant to demonstrate the system and its components operate collectively as designed, that individual components operate at varying loads under steady state conditions with their stated operating parameters, and that the components and system respond correctly to transient and emergency conditions. This may include:
- Testing for reliable start ups (this should include at least 3 starts)
- Testing for reliable controlled shut downs
- Testing for reliable continuous operation at no less capacity than that achieved in the performance test
- Testing for reliable output to correct specification
- Functional testing of all plant to confirm compliance with the design basis and operating criteria
- Update all affected documentation to as built status including
- Piping and instrumentation diagrams (P&ID)s
- Equipment datasheets
- Buried services
- Operation and maintenance manuals and procedures
