Canmar's berm-supported SSDC drilling advances arctic technology

OSTI ID:6405837
This report describes design, installation and performance of the single steel drilling caisson (SSDC) on a subsea berm. It details key points learned from the $100-million project by Canadian Marine Drilling Ltd. installed in the Beaufort Sea. Unitized construction allows for permanent installation and hookup of the drilling rig package. Mobilization and demobilization is much simpler, resulting in quicker and safer operation than that required with a multi-caisson system. The high freeboard achieved with the SSDC unit gives much greater protection with respect to wave run-up and ice ride-up, resulting in significant operational improvements. The relatively low elevation of the submerged berm at 9 m below sea level results in improved berm stability and erosion resistance.
