McConnell Dowell joint ventured with ITP (IMJV) and was awarded the EPC contract for the VTB (Vacuum Tower Bottoms) Subsea Pipeline for ExxonMobil in Jurong Island, Singapore.

IMJV was an ideal partner, having over 45 years of combined experience in specialist PIP (Pipe-in-Pipe) design and supply, EHT (Electrical Heat Tracing) engineering and local Singapore knowledge in civil and marine works.

The main scope of works included:

  • EPC of a 2km 12” electrically heated PIP (18” outer pipe) high temperature subsea pipeline
  • Subsea trenching and protection
  • Shore crossings
  • Pipeline end termination
  • Controls/monitoring systems
  • Cathodic Protection (CP) isolation

The PIP EHT subsea line is a world first in downstream industry - the pipeline operates above 200°C, making it the hottest subsea pipe in the world. This critical subsea pipeline transfers VTB to Jurong Island for additional processing.
