Rafferty’s have secured a sizable contract to carry out maintenance works on 2 No. 89m high twin flue steel chimneys and 1 No. 33m high multi flue steel chimney for a valued customer in London, UK.
The maintenance works are planned to start at the end of September and will require a specialised team of steeplejack operatives for a duration of nearly 8 weeks.
Rafferty’s have successfully completed emergency structural repair works to 2 No. steel chimneys on a Power Plant in the South West of England.
The 65m high x 6.3m diameter stacks had suffered corrosion attack and deterioration to the steel shell which required immediate structural plating works. An innovative scaffolding arrangement enabled safe access for our steeplejack and welder plater operatives to undertake the works from both inside and outside of the structures throughout their full circumference.
Rafferty’s highly specialised workforce along with their vast experience of structural repairs to steel chimney structures proved paramount on this project. Our swift and professional approach ensured the future structural integrity of these chimneys, much to the relief of our valued client.

Rafferty Steeplejacks have recently carried out an external and internal inspection of 2 No. HRSG steel chimneys for a valued client on a power station in the South West of England. The internal inspection revealed that the 2 No. chimneys had started to buckle in a specific area on both stacks. Following further investigation works externally it was determined that the buckled areas corresponded to the position of external cladding rings which had been holding moisture and deteriorting the chimney shell externally.
The two HRSG steel chimneys stand approximately 65m high above ground level and have a diameter of 6.3m. With the strucutral integrity of these huge chimneys now hanging in the balance, Rafferty’s carried out detailed design calculations, formulated a suitable repair method and, to the relief of the client, mobilised a team of 8 highly trained steeplejack and welder plater operatives to site within 24 hours. The two teams of 4 are now working in tandem on both chimneys and are carrying out structural plating and strenghening works thoughout the full circumference of the chimneys in the defective areas.
Rafferty’s unrivalled design capabilities and knowledge of steel chimney structures have proven paramount in this emergency situation and their employment of a highly specialised workforce have enabled a prompt and professional service to be provided at very short notice.
