Norwegian specialist PSI developed a remote-controlled pipeline isolation system called the PSI SmartPlug. The system is described as a DnV-approved, double block and, high pressure, bi-directionally piggable, failsafe pipeline isolation device. This system allows repairs or maintenance to offshore pipelines without the need to empty or depressurize the line.
