Sable Offshore restarts production at Harmony platform in California
Sable Offshore has restarted production at the Harmony platform of California’s Santa Ynez offshore complex after the U.S. Pipeline and Hazardous Materials Safety Administration reclassified the onshore pipelines as interstate and approved the restart plan on 22 December 2025. The complex, which includes the Hondo, Harmony and Heritage platforms, was acquired from ExxonMobil in 2024.
