NFPA 59A (2001) also requires the DEGADIS or FEM3A models to be used to calculate vapor dispersion distances, however formal interpretations by DOT PHMSA have imposed additional requirements, requiring other models to calculate vapor dispersion exclusion zone distances.
Although the DEGADIS model can calculate vapor dispersion distances from LNG pool spills, it cannot calculate dispersion resulting from a jet release.
The new approved models are able to model jet releases as well as liquid spills, effectively replacing DEGADIS as the modeling tool for LNG facility siting for 49 CFR, Part 193 facilities.
