The Release Sub System (RSS) is designed for controlled release of stuck toolstrings. When placed at the top of the tool string in place of conventional cable head weak points, heavier toolstrings can be safely run thus reducing the number of runs required. The RSS is activated by surface command or in memory mode, enabling controlled release even with damaged cable.
