Harsco Infrastructure has designed and installed two bespoke mobile access systems to allow contractors to carry out essential maintenance work at Peterborough Power Station.
The cleaning and re-painting of air cooled condenser units involved working on enormous horizontal steam pipes, with obscure angles making the ACC units inaccessible by conventional means.
The access system also had to withstand surface temperatures on the pipes of 65 deg C.
Harsco’s design employs self-propelled work platforms suspended from a steel framework.
The entire rig travels along the pipes on a series of wheels which are specially angled to accommodate the cylindrical surface of the pipes.
Contractor East Coast Industries commenced work in early September 2009 and is due to complete the contract by the end of 2010.
