Rocksteady QD is our Quick Disconnect variant of the Rocksteady subsea mooring connector, developed exclusively for our sister company InterMoor and available as the Inter-M Release.

It is used for rapid disconnection of mooring lines subsea, typically for weather and iceberg avoidance, or pre-lay mooring relocation, in MODU applications.

Rocksteady QD is equipped with a Teledyne Marine acoustic modem and an advanced control system developed by SRP, that monitors the connector condition and line tension, and releases each connector in a fraction of a second.
