Abstract: Grounded Ice pads constructed upon natural Ice rubble fields are being considered as foundations for drilling rigs, and as protective ice barriers around drilling structures in the southern Beaufort Sea. Sprayed ice Is an attractive alternative to flooding techniques for construction of these pads. The spraying technique produces ice at rates 50 to 100 times faster than flooding. This is significant because it enables the pad or barrier to be completed within the time frames necessary to drill well before spring breakup, or to protect a structure against mid and late-season ice forces. The design considerations, construction procedures, and measured properties for an experimental ice pad constructed from sprayed ice on a natural ice rubble field are discussed.
