CORROSION ISSUES


• Steel Surface Condition – an abrasive blast cleaned standard is required for optimum performance but Ultra High Pressure water jetting can also be very effective on existing corroded steel work which has been previously blast cleaned. Surface tolerance is good and surface “gingering” of steel can be accommodated without compromising the performance of the applied coating


• Application – spray application does require the use of purposely designed and configured plural component hot spray equipment operated by trained and skilled personnel. Given correct equipment and operators application is rapid as the full coating thickness is applied in a single wet on wet spray application with fast dry and curing times under almost all environmental conditions


• Impact and Abrasion – resistance is of the highest order of all organic coatings and exceeds many including plastics and composites. High tensile strength combined with good flexibility provides a highly durable coating proven under severe impact and sliding abrasion loads


• Ease of Repair – this can be carried out with hand grades to localised areas if required or by spray application following re-preparation of the steel and coated surfaces


• Performance – there is over twenty five years proven maintenance free performance in a variety of industries and applications including off shore splash zones and structures, pipelines, bridges and structural steelwork and water retaining structures


• Time to First Maintenance – with a proven twenty five years service life and following critical inspection and examination of some of these structures forecasts of up to fifty years have been made


Such a system would seem to meet the requirements of the offshore energy business where demands are being made for cost effective long life maintenance free performance and there is evidence of lack of such performance on some past projects.


SURFACE PREPARATION


As with all surface coatings preparation and application standards are critical for long life maintenance free success and to this end the product needs to be correctly specified and applied by competent applicators.


PROJECT PARTNERSHIP


The way forward is in a genuine partnership arrangement with the client end user, fabricator, blasting and coating contractor and coating supplier.


Given the willingness to succeed going in and the right communication and cooperation levels throughout the project there is a way to produce long life, cost effective, maintenance free structures for the rapidly developing offshore energy market.
