Interdependencies emphasized with british petroleum bpxa spill in prudhoe bay
Interdependencies Emphasized with British Petroleum (BPXA) spill in Prudhoe Bay

March 2, 2006 - Internal corrosion caused a 5,000 barrel crude oil spill onto the Arctic Tundra.


Phmsa actions
PHMSA Actions spill in Prudhoe Bay

March 15, 2006

  • PHMSA orders BPXA to run cleaning pigs to remove solids from the lines and perform in-line inspections (smart pigging)


Another leak
Another Leak spill in Prudhoe Bay

August 5, 2006

  • BPXA discovers a location where crude oil has leaked through the pipe wall. Based on that discovery, BP initiates shut-down of this segment of the Eastern Operating Area.


Phmsa actions1
PHMSA Actions spill in Prudhoe Bay

August 10, 2006

  • PHMSA orders BPXA to perform extensive ultrasonic tests on the entire length of the WOA (still in operation) and the EOA (temporarily shut down)




And all sizes
And the August leakall sizes…

.


Progress to date
Progress to Date the August leak

  • September 22 - PHMSA approved re-start of the 34” EOA segment for cleaning and in-line inspection.

  • October 15 – in-line inspection commenced on EOA.

    • Preliminary results under review by PHMSA

    • No immediate indications or cause for concern

  • To date - BPXA has performed ultrasonic inspection (or alternative technology) to locate metal loss on over 60% of the WOA and over 70% of the EOA. Inspection still continues today on the WOA.

  • Next steps - BPXA is preparing the WOA for in-line inspection and plans to launch a pig soon.


Impact of bp spill on phmsa initiatives
Impact of BP spill on PHMSA initiatives the August leak

  • Confirmed that PHMSA can effectively bring enforcement actions on non regulated, but jurisdictional pipeline facilities.

  • Accelerated rulemaking on low stress hazardous liquid pipelines in Unusually Sensitive Areas. Proposed rules were published in August, 2006.
