A damaged CHS member within the PLUTO LNG flare tower structure at the +114m level was identified during UAV inspections. The member had broken along the tongue plate to the CHS member connection point. A project was initiated to remove the members and other at-risk members under the same stresses.
Pluto Flare Maintenance
Vertech’s multi-disciplined, specialist maintenance teams worked on 24-hour operations to replace 12 CHS members; install DROPS protection for all horizontal members (clamp & chain assembly); perform an inspection using ECI & MPI NDT methods; replace the flare ignitor frames, cables & pilot gas hoses; and complete a close visual inspection of the flare tips.
The Challenge
An opportunity existed to shut down Pluto Train 1 in April/May 2019. During this outage, preventative & corrective maintenance was planned.
The integrity and functionality of the flare structure were critical to production on this project, and therefore, Vertech needed to provide the appropriate skills to perform the necessary maintenance on the flare.
The Solution
Vertech Group completed this flare maintenance by performing non-destructive testing (NDT) procedures on the flare tips, obtaining critically accurate data, and ensuring the flare’s longevity.
