The blast prompted gas prices to surge across Europe, including a 40% rise in the UK to 95p per therm - a level not seen since 2013.
A spokesman for National Grid said there was sufficient gas to meet demand. The outage followed the closure of the Forties pipeline for repairs on Monday after a crack was discovered.
The pipeline, which carries 40% of North Sea oil and gas, is expected to be closed for a couple of weeks while repairs are carried out.
Analysts at Jefferies said: "The timing of the outage could not be much worse as winter weather is just materialising."
Oil prices also surged, with Brent crude pushing above $65 a barrel for the first time since June 2015 though it later slid back below $64.
