After reading about flare header failures due to high velocities, an owner of a production platform in the Middle East wanted to ensure that the initial inerting/purging of the platform and pipeline would not result in flare header piping failure. Smith & Burgess was hired to review the flare systems for safe operation under the high flow rates associated with the initial facility start-up.

Liquid-certified devices are mechanically designed and sized by an engineer to relieve liquid. Per UG-125 of ASME Section VIII, "Vessels that are to operate completely filled with liquid shall be equipped with pressure relief devices designed for liquid service, unless otherwise protected against overpressure."
