REDRUTH, UK –Severn Subsea Technologies has developed Zone 0 rated, tool detection sensor technology designed 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 way to locate the tool string other than relying on visual methods. It locates 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.
The whole system, including the control box and rechargeable battery, is ATEX and IECEx certified intrinsically safe equipment for use in Zone 0 gas environments.
