CNOOC Deep Sea No. 1 Offshore Gas Field Fire Causes Extended Outage

Occurred 22 May 2026·Detected 23 May 2026·
🇨🇳 Deep Sea No. 1 (Lingshui 17-2) offshore gas field, South China Sea, approximately 150km southeast of Sanya, Hainan Province, China2 reports
Energy & InfrastructureEnergy

A fire at CNOOC's Deep Sea No. 1 (Lingshui 17-2) offshore gas field in the South China Sea, approximately 150km southeast of Sanya, Hainan Province, has triggered a production halt. Trade media report a potential outage of up to six months, though this duration has not been confirmed by the operator or authoritative channels. Chinese buyers have reportedly restarted spot LNG procurement in response to the supply disruption. No insured loss estimate, business interruption quantification, or reinsurance trigger is currently evidenced, and facility-level damage details remain sourced to trade press only.

Impact verdict

Medium impact. MEDIUM: Two independent Energy Intelligence trade-media items establish a credible production halt at a major CNOOC offshore gas field and a measurable LNG demand response from Chinese buyers. However, the reported six-month outage duration, facility-level damage details, and any insured loss or business interruption quantification remain unconfirmed beyond trade-press sourcing. The event is developing and contingent on authoritative confirmation of operational impact, loss estimates, and insurance/reinsurance positioning.
