6" Fuel gas line

Lessons Identified

Other than the inspection strategy, which leaves up to a 7 year gap between inspections, there is no process in place to prevent/monitor and repair damage to lagging before corrosion occurs. Whilst the strategy is considered to be robust there is a lack of assurance activities surrounding it to prevent a repeat of the incident since there is no particular reference made to CUI (corrosion under insulation) in the performance standard.

Incident Recommendations

Remove the remaining lagging on the 6” fuel gas line and inspect closely for any signs of corrosion

Inspect insulation local to the area for indications of CUI, damage, or deterioration.

Review the current inspection strategy for this and similar pipework within the standard inspection model.

Raise awareness of CUI and the consequences of damaged paintwork in the corrosion awareness programme
