Mitigation measures have been categorized as one of the essential elements that require furtherinvestigation in determining the potential impact on public safety from an LNG spill. Several outdoorLNG spill experiments were conducted at the Brayton Fire Training Field to verify the effectiveness ofthe direct application of a water spray on LNG vapors as part of LNG Safety and Spill Responseresearch at the Mary Kay O'Connor process Safety Center (MKOPSC) at Texas A&M University(TAMU). Theoretical modeling was conducted of LNG forced mitigation using an upward-orientedconical water spray application. The computational fluid dynamics (CFD) model had been applied toinvestigate the dominant physical mechanisms involved in LNG forced mitigation and essential keydesign parameters were evaluated. Findings from the experimental and theoretical analysis on the LNGforced mitigation are summarized. Finally, recommendations on designing an effective forced mitigationsystem and potential hazards of applying the water curtain system are discussed. This work aims toprovide a comprehensive understanding of the forced mitigation system with direct application to LNGfacilities.
