In conjunction with our sister company – InterMoor – we developed the proven Rocksteady subsea mooring connector into an acoustically operated quick disconnect connector: Rocksteady QD, marketed as InterMoor’s Inter-M Release.
A quick disconnect connector is loaded with energy that releases the connector at the press of a button, this functionality can save days of rig time, and even protect assets from extreme weather events. However, the connectors are part of the mooring system that keep drilling rigs in position over a well, so managing the risk of accidental release while providing the required availability presents a significant engineering challenge.
SRP managed this risk through FMECA based design methodology and a rigorous testing program that included control software unit and user testing, and extensive factory acceptance testing.
By issuing type approval, DNV has certified that the integrity of the Rocksteady QD acoustic release meets or exceeds the system reliability requirements set out in DNV-OS-E301 for Position Mooring.
