Benefits
Woodside’s suite of asset specific subsea pipeline repair plans and associated documentation now reflected current market capability from vendors, contractors and available repair methodologies. In addition, each repair plan was revised to consider each pipeline’s business criticality which was used to inform decisions on pre-investment and repair methodology. The updated plans will now, in the event of pipeline damage which leads to emergency repair, enable a quicker repair with less impact to production and further reduce the risk of long-term pipeline damage due to prolonged exposure to raw seawater.
Background
In December 2014 Woodside Energy Ltd revised its over-arching Subsea Pipeline Repair Strategy document. Woodside requested Atteris to revise five subsea pipeline repair plans as well as associated documentation and make recommendations for subsea pipeline repair acceleration opportunities which would reduce business risk.
