Severn Subsea Technologies (SST) has developed Zone 0 rated, tool detection sensor technology to reduce the risk of damage to the riser assembly during drilling and intervention operations, as the tool string is recovered to the surface.
The Tool Detection Alarm (TDA) offers a safer method of locating the tool string than relying on visual methods alone. It positively locates the position of the tool and sounds an alarm, alerting the winch operator to take action to prevent the tool string hitting the riser seal head. The portable, battery-powered TDA provides an extra layer of protection minimizing the risk of damage to completion equipment and potential loss of the tool string down the well.
