Norwegian gas-transport operator Gassco extended Heidrun’s 5.5-million-cubic-meter-per-day supply outage through October 5, from the previously scheduled October 4.

Gassco revised the reported outage window at the Heidrun field (海德伦气田). The original window ran from September 29 through October 4; the revised window runs from September 29 through October 5.

The affected supply figure remains 5.5 million cubic meters per day. This is a daily natural-gas supply quantity associated with the outage, not a cumulative lost volume or an electricity-generation capacity figure.

The update changes the scheduled end date rather than confirming a restart. The supplied message gives no outage cause, repair detail, customer allocation, or quantified effect on gas prices or power markets.
