Caisson retained islands are a type of exploration platform suitable for the Arctic continental shelf. Gulf Canada Resources Inc. (GCRI) have adopted this platform concept for exploration of their Beaufort Sea acreage, the GCRI system being called the Mobile Arctic Caisson. Construction of a berm for the caisson at the Kogyuk N-67 wellsite was carried out during 1982. Details on hydraulic fill placement methods, quality control measures and post construction fill density verification are presented. Data is given on construction times, effect of quality control measures, sideslopes achieved and the sand fill in-situ density. The economics of caisson retained islands depend on obtaining both an adequately dense hydraulic fill without mechanical compaction and relatively steep sideslopes. The data and methodologies presented form a significant case history demonstrating that the two objectives can be achieved.
