NOPSEMA correspondence from July 2019 regarding a shutdown event on the Northern Endeavour floating production facility operated by Upstream Production Solutions. A NOPSEMA inspector inquired about an emergency shutdown event that potentially caused vibration leading to a corroded pipe support failure in the LP flare header. The operator clarified that a controlled process shutdown (PSD) occurred rather than an emergency shutdown (EDS), meaning no facility muster or emergency systems were activated. The shutdown was triggered by a transmitter failure on the turret's common gas lift supply line downstream of gas lift compressors. Plant recovery operations commenced without issues and were substantially complete by 23:00 hours on the same day.
