摘要
A method and apparatus are for supplying liquids for scale treatment and killing to a subsea well, where the subsea well is provided with a tree which has a swab valve and a coupling for a tree cap. The method comprises: arranging an upgrading module on the tree after the tree cap has been removed, the upgrading module comprises an electric control unit and a tree cap which via an intermediate conduit is coupled to a top valve at the upper portion of the upgrading module, coupling a coupling column comprising at least two column valves and a quick-releasable coupling to the top valve, the coupling column communicates with a vessel via a hose connection; coupling the control unit to the vessel via a signal wire running within or close to the hose connection, thereafter the tree and the upgrading module is controlled via the signal wire; opening the swab valve, the top valve and column valves; and pumping liquid from the vessel via the hose connection, coupling column and upgrading module down into the subsea well.
