Fremgangsmåde til elektronisk in situ bortskaffelse af metalkonstruktioner

摘要

A method of dissolution of metal structures in a conducting fluid comprises connecting said structure to the positive terminal of a DC power supply and immersing a cathode connected to the negative terminal of said power supply in said conducting fluid. The metal structure is preferably iron or steel and has application in dismantling offshore oil or gas installations. The conductive fluid is preferably water.
