On June 8, 2022, piping at an LNG Terminal failed, resulting in an explosion and fire. The explosion and fire occurred entirely within the fenced boundaries of the facilities. The facility immediately shut down its operations and notified first responders. With assistance from local fire departments, the fire at the terminal was brought under control and extinguished.
PHMSA, in coordination with FERC, required the facility to conduct a root cause analysis prepared by an independent third party. The Root Cause Failure Analysis was reviewed and approved by both PHMSA and FERC. As described in this report, which was filed in the Commission’s administrative record (a public version was also released by PHMSA), this failure occurred due to the warming and expansion of LNG within the piping and an improperly isolated pressure relief valve.
