This project was a major expansion project BAPCO had undertaken in 2005 consisting of a new grass root complex and modifications to the existing No. 2 Hydro Desulphurization Unit (2 HDU) to enable the production of all diesel from the Refinery at 0.001 wt % sulphur. It involved the modification of utility and off-site refinery networks and tie-in to existing systems. While JGC Corporation was the EPC Contractor for this project MCSC was the General Contractor for the brown field activities carrying out all the civil, mechanical, electrical and instrumentation, insulation and fireproofing works.

During the second 30 days shutdown which had to be scheduled during the summer peak, major works completed include replacing the existing vacuum column with the new one, modifying/replacing 91 process and other equipment, tie-in and hydro test of piping systems, painting, insulation and electrical works.
