Enbridge has declared force majeure on its offshore Nautilus natural gas pipeline system after Gulf of Mexico producers shut in supply in preparation for Hurricane Alex.

Daily gas production approaching 100 million cubic feet was shut in on the 103 mile, 600mcfd capacity Nautilus line, Enbridge spokesperson Terri Larson told Reuters.

The company has also cut some scheduled deliveries and evacuated non-essential personnel from its Garden Banks and Stingray pipelines, offshore Louisiana.
