RAP upgrades to meet demand

The RAP de-bottlenecking project was implemented in three stages.
The aim was to increase the flow rate through the line.

  • Pre Phase 1 - 1985+ 255 m³ per hour
  • Phase 1 (1 pump at IPS1) - 1999+ 258-315 m³ per hour
  • Phase 1A and 2 (2 pumps at IPS1 and 1 pump at IPS2 - 2005+ 370 m³ per hour
  • Phase 2A - Future Project - Use of Drag Reducing Agent in products other than Jet A1 at Marsden and IPS1 - 415 m³ per hour
  • Phase 3 ( 2 pumps at IPS1 and 2 pumps at IPS 2) - Future Project 415 m³ per hour
