Project Overview
Decom Engineering was engaged by MMA Offshore for Woodside's Stybarrow decommissioning campaign, requiring precise cutting of a 4" flexible flowline at 850m to enable safe recovery and NORMs inspection. C1-24 units 102 and 108 were crane deployed and ROV powered with Decom-supplied hotstabs, completing over 100 cuts with an average time of just 3 minutes and a rapid 10-minute cut-to-cut cycle at 12-metre spacings.
Key Highlights
- 100+ clean cuts enabling immediate NORMs inspection
- 10-minute cut-to-cut cycle across 12-metre spacings
- C1-24 fleet (units 102 & 108) with Decom-supplied hotstabs
