Abstract
A series of pressuremeter creep tests was run in the spray ice of Man Island in March 1986. Individual constant pressure tests lasted up to 5 days. The island itself was constructed in January and February of 1986 and was used as a drill platform for petroleum exploration in the Alaskan Beaufort Sea. The island was expected to break up or float away during the summer of 1986. It is possible to compare the creep behaviour of the spray ice as interpreted from the pressuremeter tests with the creep behaviour interpreted from the island settlement records. Comparisons are made for both primary and secondary creep on the basis of conventional power law creep theory. The pressuremeter offers the potential to be an excellent quality control device during the manufacture of spray ice island. Constant pressure tests of one and two days duration could be used to check the design assumptions pertaining to the expected consolidation of the ice mass with time, consolidation of the ice mass has important implications both for lateral stability of the island (the island's ability to resist lateral forces) and for settlement of the drill rig (in particular the relative settlement of the drill rig with respect to the blow-out preventer.)
