Abstract: A method for accelerating the freezing of sea water by two different, but related approaches. One involves the use of fluorinated or fluorochemical surfactants, other surfactants with specific activity in saline water, and the other by treatment with ice nucleation agents or the use of both. The specific application for the process is construction of improved load bearing ice structures as used in Arctic regions in supprot of hydrocarbon exploration and production activities.
