09/03/2026- Nautilus Force Majeure - Unplanned Outage at Enterprise Neptune plant - Update

SEV 4/5Force MajeureUntil further notice

Summary

Nautilus Pipeline has declared force majeure following an unplanned outage at the Enterprise Neptune offshore processing plant, effective September 3, 2026. The plant continues troubleshooting with no estimated restart timeline, and Nautilus is reducing all scheduled quantities to EPSQ (Elapsed Prorata Scheduled Quantity) for the Intraday 3 cycle on the September 3 gas day. No restoration ETA has been provided, and the notice end date extends to December 2, 2026, suggesting a potentially prolonged constraint.

Trading note

Nautilus force majeure with no restart ETA removes offshore GoM supply volumes from the onshore market indefinitely; bullish for Henry Hub spot and Gulf Coast basis with duration risk extending into Q4 2026.

Reroute potential

None: Nautilus is an offshore gathering pipeline serving the Enterprise Neptune plant directly; there is no alternative routing for production shut in at this offshore facility.
