Around 500 unsupported pipeline lengths, freespans, have been identified on the SAGE pipeline (lengths 10m‐57m/ gaps 0.1‐2.0m)
5 of these were addressed in detail as the spans fail the pre‐determined criteria
1 freespan was rectified in March 2012 at the Beryl Alpha SSIV (44m) to prevent any potential for further growth and requirement for annual monitoring
4 remaining critical spans will be re‐inspected in 2012
