ABSTRACT:

This is the first field proven Remote Controlled (tether-less) Pipeline Isolation system, enabling the performance of pipeline maintenance and repair operations in ways previously not possible, in addition voiding the need to reduce pipeline pressure, flare or displace pipeline inventory. It is a DnV Type Approved, double block and (initial) bleed, high pressure, bi-directionally piggable, pipeline isolation device, operated and monitored entirely via remote control (tether-less) using PSI's proprietary through-wall control and communication system, enabling the operation of the tool anywhere in a pipeline, through the transmission of commands and the reception of pipeline and operational data through the pipe-wall.
