01
What an AGO STACK is, and why this scope mattered
An Acid Gas Oxidizer (AGO) stack is the destruction column for sour-gas streams in oil and gas processing. Two units, each forty metres long and 2.8 metres outer diameter, plus a 4.2-metre-diameter combustion chamber: the fabrication scope demanded the full envelope of PSE Malaysia's heavy-iron capability. 300 MT/month fabrication capacity, 9-metre hook clearance, 20-ton overhead crane, post-weld heat treatment up to 40 metres long.

The Kerteh shop, by the numbers
The Kerteh facility was established in 2014 and fully operational by December 2019. The shop sits on a 5.56-acre site in the Kerteh industrial area, with three fabrication shops (two at 25 × 90 × 11.5 m, one at 28 × 90 × 11.5 m), three blasting and painting bays and a 4 × 40 m post-weld heat treatment furnace.
