PROJECT 23
ORSCO attends to pipe rehabilitation .
2 . Client-led manual repairs : FFS Refiners assumed responsibility for :
• Structural assessments and necessary internal pipeline repairs
• Providing skips for sludge disposal and managing site traffic
3 . ASOE Oil Liner installation : ORSCO executed the liner installation , encompassing :
• Site establishment and preparation
• Line stringing and pipeline flushing
• Precision installation of the ASOE Oil Liner
• Flanging and securing the liner to the pipe structure
• Site clean-up , waste removal , and final client handover
FFS Refiners conducted the final pressure test post-installation to validate the system ' s integrity .
Project impact and conclusion The successful completion of the FFS Refiners pipeline rehabilitation project represents a significant advancement in African pipeline infrastructure . The ASOE Oil Liner ' s close-fit design and hydrocarbon resistance provide a long-term , durable solution , ensuring pipeline efficiency and safety .
ORSCO ' s expertise in trenchless rehabilitation has established a new benchmark for innovative , non-invasive pipeline repair . The project not only minimised operational downtime for FFS Refiners but also demonstrated a sustainable and cost-effective alternative to traditional excavation methods . The project highlighted ORSCO ' s ability to adapt to unforeseen challenges , such as the sediment-filled chamber , and deliver a successful outcome .
