Sasol Steam Station 2 Main Header Replacement - Tie-Ins Scope
Discipline: Structural, Mechanical and Piping
Sector: Steam & Power, in Gas Plant
Sasol’s Steam Station 2 in Sasolburg underwent its first planned shutdown since being commissioned in 1968. The primary purpose of the shutdown was to positively isolate the main steam header in order to allow Sasol to safely remove and replace the main steam header whilst exporting steam by means of the auxiliary header. This was done by means of cutting out old valves and/or spool pieces, and installing flanges with spectacle blinds, into which the new main header would tie back into upon completion of the main header replacement. In addition to this, the scope also included maintenance work in the form of replacing valves that were previously leaking through, as well as installing new valves where previously there had been none, in order to provide Sasol operations, the ability to isolate the auxiliary header between boilers. There were 27 tie-ins in total, of which majority were large bore chrome moly tie-ins ranging from 8” to 20” executed in a confined space using clean construction methodology. The project was completed without any safety incidents recorded and with a Zero weld failure rate.

Sasol Steam Station 2 Main Header Replacement - Tie-Ins Scope
Discipline: Structural, Mechanical and Piping
Sector: Steam & Power, in Gas Plant
Prommac were awarded the mechanical, electrical, instrumentation and piping scopes for the Sasol Caustic Plant Upgrade Project in 2016.
Prommac demolished and replaced approximately 1000m of piping electrical cabling during a shutdown period. The piping comprised of various sizes with the majority being 2” and below and included the supply and fabrication of the piping. Being Caustic Plant, significant effort was made to ensure the safety of the team was maintained at all times. The project was completed successfully, on time, in budget and with no recorded safety incident.
Testimonials
“Our performance to date as a team has been exceptional. This happened because each and every person just did their part and executed their plan. The commitment from all disciplines and contractors is what made our shutdown much more easier to manage. For that I say thank you for your leadership and please pass our appreciation to all those that executed the physical work on the ground. Without their tireless effort; none of this would have been possible.
Much appreciated”

“I’d like to give recognition to the team for the assistance in installing the pipe-work for the Outside Battery Limit (OBL) Mobile Skids Piping.
I must also commend the team on your level of professionalism. The initial scope for Prommac was simple and straight forward, but as the project progressed, we ran into a NUMBER of challenges. The team were always willing to assist, and often went out of their way, and out of their original scope, to assist in getting the job done despite the challenges.
I am looking forward to working with Prommac at large, on other future projects.”
