The tank lids and walkway gratings were transported from Hartlepool Power Station to the CSC Services work unit for the refurbishment work as part of a plant upgrade.
The steel gratings were grit blasted to provide the correct surface profile for the application of marine grade protective coatings to be applied. This was specified to protect against chloride attack at the coastal location of the power station. The images below show the work in more detail.
Abrasive blasting equipment was used to remove failed coatings from the Ferrous Sulphate Tank Lids. New marine grade GRP protective coatings were applied, again to protect against salt and chloride attack. This consisted of a primer undercoat and top-coat. Two clear protection coats were applied before waxing and polishing to complete the job.
Mick Flounders, Contracts Director at CSC Services explains why offsite work is beneficial:
“Offsite work is useful when the structure to be prepared and cleaned for coating through a process such as shot blasting is situated in a sensitive area such as a power station. By taking structures offsite for refurbishment work, day to day operations can continue.”
CSC Services are offsite industrial painting contractors who have many years of experience preparing and coating pipework and various other structures. Structures, pipes or equipment of up to 3m wide can be forklifted in and out of the specialist unit.
