Tube Tech was the only company in the competitive tender which could satisfy the desired criteria of using the existing walkways to clean the tubes 35ft above. "Other companies had advised the use of rope access or secondary staging to reach the full extent of the tube surfaces," explained a DCL spokesman.
Only Tube Tech advised they would be able to carry out the cleaning in the way considered the safest option. Faced with the largest and highest Apex Air Cooled Condenser (ACC) it has tackled - covering 34,000 square metres of bare surfaces - Tube Tech used several different systems and also developed an additional technique which involved a hi-tech light weight alloy system and a handling process specific to the site.
