Pipeline pre-commissioning, what does it mean to you?

“Pre-commissioning” refers to investigations and planning in advance of the commissioning phase, and greatly benefits constructors and facilities operators. In general terms, pre-commissioning can be described as the activities and procedures performed on a pipeline, process module, subsea structure, flexible or umbilical to provide assurance that the component parts are leak-free and are in a suitable state of cleanliness and readiness prior to commissioning and long term operation of the system.

Many areas of Offshore Energy’s work environment consider these activities:

  • Flooding / filling
  • Remote or subsea flooding
  • Cleaning
  • High velocity flushing
  • Gauging
  • Hydrotesting / pressure testing
  • Intelligent pigging
  • Controlled bolting
  • Tie-in leak testing and leak detection
  • De-watering
  • Nitrogen purging and packing
  • Drying
  • Conditioning
  • Nitrogen / helium leak testing
