Project Overview
Decom Engineering was selected by DeepOcean to support Shell's decommissioning programme in the UKCS. Delivered over two three-month scopes, the C1-24 cut flexible risers and rigid pipelines including carbon steel and super duplex at 160m depth. The saw's robust frame lifted and cut partially and fully buried pipelines without extensive dredging.
Key Highlights
- Cut times of 10-25 min depending on material type
- Cut buried pipelines without extensive seabed dredging
- Outperformed alternative solutions across two extended campaigns
