TDW uses its SmartPlug tool to isolate pressure in specific sections of pipelines and risers so that repairs or interventions can be carried out safely. Operated by remote control, the tool is certi- fied to "Safety Class High" in accordance with OS-F101 for submarine pipeline systems. It is certified and type-approved to execute independent double-block isolation to provide a safe environment for divers while working near a pressurized gas pipeline. The company's remote-controlled SmartTrack tracking and monitoring system uses two-way, through-wall electromagnetic communication between a transponder and a receiver to track the tool's progress, control its speed, and monitor conditions in real-time.
