Stefanutti Stocks’ capabilities within the Oil & Gas Discipline include the fabrication, construction and maintenance of process plants across South Africa and neighbouring countries.

We offer the Industrial, Oil & Gas sector a construction solution through to commissioning, as well as a single-point responsibility that eliminates traditional inter-discipline co-ordination.

Our decades of experience in the sector, combined with our broad spectrum of expertise within our multidisciplinary group supports our ability to deliver world-class petrochemical construction projects. We own and operate a full range of construction equipment and manage our own logistics to support efficient project execution.

excellence in execution

We recently completed Transnet’s SAPREF R Tanks, in joint venture between Stefanutti Stocks Oil & Gas and JV tanks South Africa. This project included the welding of two 36-metre diameter, 20-metre-high storage tanks, the assembly of the tanks’ aluminium dome roofs, internal floating roof, hydrotest and all painting up to final coat. The civil apron and finishing works were included in the scope.

In 2021 Stefanutti Stocks also completed Astron Energy’s Crude Flex Project in Cape Town. This project encompassed the installation of interconnecting piping systems between multiple tanks across the refinery, including all mechanical, piping, civil and electrical and instrumentation work (under permit conditions).

Sasol’s Vessel Replacement project, including the replacement and welding up of three columns, with associated structural and piping installations, was undertaken during a sixty (60) day, 24-hour shutdown.
