Austerity can only be implemented in the shadow of a concentration camp.

Unlikely - Piper and Brent were not served by the same pipeline:

OPCAL built the Flotta oil terminal in the Orkney Islands to receive and process oil from the fields Piper, Claymore and Tartan, each with its own platform. One thirty inch (0.762 metres) diameter main oil pipeline ran 128 miles (206 kilometres) from Piper Alpha to Flotta, with a short oil pipeline from the Claymore platform joining it some twenty miles to the west. The Tartan field also fed oil to Claymore and then onto the main line to Flotta.[3] Separate 46 cm diameter gas pipelines run from Piper to the Tartan platform, and from Piper to the gas compressing platform MCP-01 some 30 miles to the Northwest.

You would have expected only Claymore and Tartan (too small to be named in Euan's chart) to be affected. Ninian didn't suffer a dip in production - that's an optical effect from the chart.
