TY - BOOK AU - Byremo Helleren, Elisabeth TI - Gel displacement supports subsea flowline decommissioning without production interruption PY - 2026/// N2 - Mature offshore fields often require subsea flowline decommissioning while adjacent infrastructure remains in production, limiting conventional methods. Using a chemically engineered gel displacement system to remove hydrocarbons from two late-life pipe-in-pipe subsea flowlines in the Norwegian North Sea, the project demonstrates a repeatable approach for late-life subsea assets ER -
