Photo gallery General: Piling at Markinch Biomass Combined Heat and Power Station. Magnetic survey of site for Staythorpe CCGT power station. Used to identify areas of possible ground contamination. Column base buckling of CHS supporting main coal conveyor. Beam close to failure at Blyth Power Station. The weight of wet insulation in poorly maintained ductwork overloaded the beam which is tearing the bottom flange and most of the web.eam close to failure at Blyth Power Station. Chimneys: Photo merge of concrete chimney at Aberthaw Power Station. This provides a high resolution detail so that rate of any deterioration can be monitored. If repairs are required the photo can be pasted into drawing so that repairs can be measured and specified. Concrete repairs to top of single flue chimney at Ironbridge Power Station. Weld cracking and plate thinning on steel GT stack at Aberthaw Power Station. Cooling Towers: Gunite strengthening of cooling tower shell at Didcot A Power Station. Cooling tower strengthening at Ironbridge Power Station. Schematic of cooling tower 3D shape survey Schematic of axi-symmetric imperfection in cooling tower. Developed elevation of a natural draught cooling tower at Didcot A power station showning shape errors of up to 300mm. The errors were increasing with time and the tower had to be stabalised with reinforced gunite. Column jacking at Ironbridge Power Station to transfer load into new columns and mini pile foundations. Work carried out prior to strengthening two towers by insitu RC mantle.
