Confined Space Rescue Team for Yorkshire Water

Posted: Friday 15th June 2012

PMP were contracted by Yorkshire Water Services to replace the guide rails of the inlet well pumps within a 27 meter deep well containing 12 storm pumps and 4 FFT pumps. PMP supplied all mechanical engineering facilities and when replacing the stainless steel guide rails, opted to access the wet well using rope access techniques to eliminate the costs and delays associated with scaffolding.

Due to the complex nature of the well, with multi-staged landings and a 6m dividing wall at the base of the well, plus outage times needing to coincide with local flows and over pumping requirements adding to the fact the well could flood with little warning, it was clear that recovery of a potential casualty from the confined space was going to be difficult and time consuming and would be insufficient to meet the needs of "suitable and sufficient" Emergency Arrangements. PMP therefore decided that they would lift one of the floor plates to gain an unobstructed, vertical, straight line to the bottom of the well, enabling a working line and a safety line to be suspended from a tested A-frame.

Using rope access techniques, the IRATA trained PMP Confined Space Rescue

Team were able to retrieve a casualty using a Z-rig, permanently set up on the working line. A practice drill, using a 85kg rescue training dummy, proved PMP we were able to recover a casualty in 1 minute 56 seconds.

Yorkshire Water Services were so impressed by PMP's rope access capability they employed PMP to provide the Confined Space Rescue Team for William Tracey Group whilst they prepared the wet well to remove excess debris from around the pump base and walkways. The whole project was completed in just 3 weeks and was finished significantly ahead of scheduled deadlines.

PMP’s Rope Access Division has been developed in response to growing demand for inspection, maintenance and engineering services to be carried out in hostile environments. For example; structures such as railway and motorway viaducts, aqueducts, towers that can only be inspected and maintained via rope access, a quicker and cheaper option than scaffolding. Added to this PMP’s Confined Space Rescue Team is also available for safety cover, giving peace of mind when working in hazardous areas.
