Rope access - The viable alternative to scaffolding
7 October 2011, News release from PMP Ltd
PMP's expertise in confined space and rope access work has distinguished the company over the past 28 years in inspection, maintenance and repair for the water industry.
PMP also has an enviable reputation for fast response to emergency call-outs and is always keen to develop and innovate.
The company had previously worked at Chellow Height WTW, back in 2009, looking at the sludge blanket hoppers where the steel work, which raises the hoppers to the correct level to decant the sludge, had bent due to excess weight. Access to the hopper support steel work meant working at height using either scaffold or rope access techniques.
PMP explored both options and found the rope access method to be more cost effective by around £17k. The company's engineers gained access to the weir channel by clipping in to horizontal tensioned lines, to eliminate the risk of falling into the empty tank, and used a further tensioned line to move materials and tools out to the fitter who was then able to remove the damaged steelwork safely. The damaged components were then renewed by reverse engineering back in PMP's workshops.
Since repairing the hopper mechanisms, Byzak called PMP to site twice more to remove obsolete pipe work and renew corroded mild steel overhead pipe brackets. These were replaced with new stainless steel reverse engineered pipe brackets and fixings.
The current works are part of a planned refurbishment program of the clarifiers and PMP will be visiting the site to complete mechanical repairs using rope access techniques to eliminate the need for scaffold in the future.
PMP are specialists in joint testing and repair for man accessible pipelines. In addition, the company's Rope Access Division has evolved in response to growing demands for cost-effective inspection, maintenance and engineering solutions carried out in hostile environments. Structures such as railway and motorway viaducts, aqueducts, towers and chimney stacks can now be inspected and maintained using rope access, a far quicker and cost effective option than scaffolding.
