Online External Airside Clean of Air Cooled Heat Exchangers (FinFan Bundle)

Offshore on a platform in southern North Sea for a large fuel exploration and production company

A large fuel exploration and production company asked us to clean the Air Cooled Heat Exchangers on a platform in southern North Sea.

Using our specially formulated chemical wash and our low pressure/high volume water jetting techniques we were able to perform an Online Air Side Clean of the FinFan Bundles.

We cleaned both product and process FinFans, 20 x 40 feet Import/Export Coolers and 8 x 10 feet Lube Oil Coolers.

We also improved fan performance by fitting Air Seals, Tip Seals and adjusting the angle of the blades and verified this optimisation with airflow analysis.

Our methods provided sufficient cooling to maintain normal operation throughout the cleaning process meaning no need to shutdown any operations and no expensive downtime.
