Another Oil Shock?

Not looking too pretty over in the UK according to the Oil Drum, even before the failure of a complex and tightly coupled system to deliver oil:

Failure by BP to recognise the dependency of the Forties Pipeline upon vital services provided by Grangemouth, and to provide contingency back up for their loss, is the principal cause for over 40% of UK North Sea oil and gas production now being shutdown.

Update 4/30: The pipeline has restarted.
