industrial services with operations in shipping, oil and gas, renewables and industry/infrastructure segments. In the trial area, the existing coating system was completely removed from structural steel tubulars and fl at plate. T e structure was power washed and degreased to remove contaminants. All tubulars were blasted to SA2.5, and fl at plate mechanically prepped to ST3. Although rust rashing was visible on areas prior to spray application of the anti-corrosion coating, this was deemed acceptable due to the coating’s particular properties. It can be applied to a damp substrate with rust rashing/fl ash rusting, and high salt levels do not degrade the coating, which reduces surface preparation requirements. T e coating can cure in a single coat 15 minutes after application, depending on climatic conditions, which expedites completion, compared to traditional coatings, which require extensive drying time between coats. In contrast to traditional coatings, which only form a physical barrier to corrosion until breached, EonCoat chemically bonds with bare substrate surfaces, providing an iron magnesium phosphate layer that prevents steel corrosion. T is process provides a very thin layer (about 2 microns) of permanent protection. A second layer – a tough ceramic outer shell – provides further protection, and also acts as a reservoir to re-phosphate the steel if needed. T is ensures the alloy layer remains intact, and allows it to “self heal” if it is ever breached by mechanical damage. During this ongoing trial, testing has been done via
cross cuts of about 6-8in in length down to the substrate to provide evidence of EonCoat’s self-healing properties.
NEXEN TRIAL
After the early success of the Total E&P trial, a second off shore trial is now being conducted. SPi applicators, as well as EonCoat material and equipment, were helicoptered to Nexen’s Buzzard platform on June 18, 2018. After Stork, a Fluor company and global provider of integrated operations, maintenance, modifi cation and asset integrity solutions, assisted with fabric maintenance and surface preparation, SPi applied the anti-corrosion coating to platform areas suff ering from severe corrosion. Although results from this second trial are still under consideration, they look extremely promising. “As oil and gas E&P companies look to combat off shore
asset corrosion, extend safe production and reduce the need for costly maintenance and downtime, we look forward to working with OGTC, Total, Nexen, Muehlhan, Stork and other platform owner/operators in the North Sea,” concludes Merrick Alpert, president of EonCoat.
