Commissioning & Start-Up of Process Units

Industrial Units


Who should attend?

  • Prepare participants to manage commissioning and start-up operations.
Audience :
  • Supervisors, engineers and technicians of oil/chemical companies or engineering, involved in the commissioning and start-up of new units.

Level : Foundation

Course Content


      • Integration of commissioning activities into the project process: mechanical completion, pre-commissioning, commissioning and start-up activities during the project steps.
      • Commissioning procedures. Interfaces with the different engineering disciplines according to the types of contract.
      • Plant/project breakdown into systems and subsystems. Execution plan for commissioning and start-up.
      • Setting up of commissioning/start-up teams. Split of responsibilities. Preparation of the list of precedents
      • Start-up phases: precommissioning, commissioning and preparation for start-up, performance tests, provisional acceptance, mechanical guarantees, final acceptance. Hand over.

      • Risks related to the auxiliary fluids and the introduction of hydrocarbons. Risk evolution between construction, commissioning and start-up. Control of the risks related to modifications during the different phases.
      • Pre-Start-up Safety Review (PSSR).

      • Precommissioning activities: static verification of equipment, hydraulic tests and equipment cleaning, involvement of operations in the mechanical completion, punch-list, actions follow-up and close out.

      • Commissioning activities. Cleaning, flushing, blowing and drying. Dynamic testing.
      • Synchronization of control loops and Programmable Logic Controller (PLC).

      • Start-up permit: checks required before oil-in. Leak tests, air removal, raw materials introduction.
      • Transition towards industrial production: performance tests, temporary and final acceptance, responsibility transfer.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • plan and manage precommissioning, commissioning and start-up activities of a project,
  • conduct or delegate these activities while controlling the specific constraints related to these operations,

Ways & Means

  • Cases studies on the precommissioning, commissioning and start-up of typical units.
  • Analysis of incidents occurred while precommissioning, commissioning or start-up phases.
