Abstract

See full text

A deep water drilling riser pressure relief system includes a drilling riser extending from a surface down to a BOP stack arranged subsea. The drilling riser comprises a drilling riser slip joint, an annular preventer arranged below the drilling riser slip joint, and at least one pressure relief device arranged in a lower part of the drilling riser. The at least one pressure relief device is configured to open so as to discharge a fluid from the drilling riser to the sea if a pressure difference between an inside and an outside of the drilling riser exceeds a predetermined threshold.
