25 GAS RINGMAIN REPAIR

26 1 ST BERYL CAMPAIGN NEVIS SOUTH REPAIR Leak at N13 (greenish fluid) 26 Well N13 leaking hydraulic fluid 165 Litres per day being discharged Decision taken to mobilise DSV Original schedule was 3 days for Nevis works SCM changed out in 10 hours All Nevis works completed in 1.5 days Well now back online, no leaks reported Airbag change out of SCM

27 1 ST BERYL CAMPAIGN SAGE FREESPAN Around 500 unsupported pipeline lengths, freespans, have been identified on the SAGE pipeline (lengths 10m-57m/ gaps m) 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 Freespan Prior to Repair 2012 Freespan Repair 27
