Commissioning of the Multi-Products Pipeline
Objective of the Commissioning
to bring the constructed / installed system to deliver the desired function
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 generatestatic 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
Commissioning of a Multi-Products Pipeline
Ensure the pipeline is ready in all respects for the commissioning
Ensure adequate product (HSD) is available for the commissioning (At least more than line-fill of a Pipeline section)
The pipeline or a section of the pipeline is pressurized with air (2 to 3 Kg/Sq-cm)
Pump a water column of about 500 kL to 1000 kL
Launch a Bi-Di Pig followed by 1000 kL to 2000 kL water
Launch second Bi-Di- Pig behind 1000 KL to 2000 KL water
Pump HSD at minimum flow
Track the movement of Pig
Vent the air at receiving end and maintain back pressure 3 to 4 Kg/Sq-cm
Monitor receipt of water at Receiving end – it may be disposed directly in to a protected pit or in a designated tank
Receive Ist Bi-Di Pig
Monitor the quantity and quality of water at receiving end
Receive second Bi-Di Pig
Once diesel or diesel mixed with water arrives, switch over to designated HSD Tank
Observe flow and pressure, once these become stable, the operation may be made normal and the pipeline may be declared as commissioned and handed over to Operation
