Subsea World Oil Online
What happened
A project used a chemically engineered gel displacement system to remove hydrocarbons from two late‑life pipe‑in‑pipe subsea flowlines in the Norwegian North Sea. The work demonstrates a repeatable method that avoids production shutdown during decommissioning and relies on validated chemical handling and subsea tooling. Watch whether follow‑on projects adopt the same method and whether suppliers bid separate line items for chemicals and disposal
Why the category manager should care
Treat the gel approach as an actionable option that should be built into supplier qualification and costing, not just an engineering footnote
Key facts
- Applied to two late‑life pipe‑in‑pipe subsea flowlines
- Demonstrated as a repeatable approach for late‑life subsea assets
