Pipeline Commissioning (English Ver.)

The Pipeline commissioning means introducing crude/ product/Gas in the pipeline from originating station, filling the entire length and then start delivering to receipt system.

What we need prior to commissioning?

• The pipeline and associated facilities are completed in all respect
• All Fire and Safety equipments / facilities are tested and commissioned
• Availability of dedicated communication
• Statutory Clearances obtained 
• Availability of Product (HSD)/ Crude oil – Not less than line-fill 
• Required Manpower is placed at all locations 
• Availability of water and its disposal plan 
• Availability of a dedicated commissioning team

Critical issues in commissioning a Petroleum Pipeline:

• Movement of hydrocarbon in empty pipeline can generate static current.
• Hydrocarbon Vapor mixed with oxygen may lead to explosion. 
• There may be formation of Air / Vapor pocket that may get compressed leading to rise in pressure. 
• Air / vapor pocket may explode in receiving tank leading to damage of the tank roof seal. 
• Leakage of any hydrocarbon may lead to fire or damage to environment
