By reproducing the inspection setup in a virtual environment, technicians can simulate hundreds of flaw variations. This helps build more reliable PoD curves than physical testing alone, which is limited by the number of defects that can be physically manufactured.

For CO₂ injection risers, F118 is valuable because CO₂ + water forms carbonic acid, and dense-phase CO₂ has unusual pressure/temperature behavior (Joule-Thomson cooling). The RP’s section on low-temperature toughness and corrosion allowance is directly applicable. dnv-rp-f118

For decades, engineers relied on general piping codes and fragmented guidelines. But as floating production storage and offloading (FPSO) units, semi-submersibles, and Spar platforms moved into deeper, harsher environments (like the Gulf of Guinea, North Sea, and pre-salt Brazil), a dedicated, holistic standard became essential. By reproducing the inspection setup in a virtual
