Court Case on Failure of Protective Coating
SE Bridge was paid to complete and/or re-work the zinc silicate coating. Etcheverry’s report shows not enough zinc silicate coating was applied. Costa was able to see where there was missing zinc silica based on the condition of the metalized coating on the photos in Bolton’s punchlist. Additionally, MTS used an inconsistent procedure for overcoating — in some instances epoxy coating was applied first, while in others the zinc silicate coating was applied first.

Asyad Drydock Applies High-Quality Nano-Epoxy Silicone (NES) Coating on Asyad Shipping’s Ultramax Bulk Carrier Jabal Al Kawr
Asyad Drydock, part of Asyad Group, announced the successful application of high-quality nano-epoxy coating on Asyad Shipping’s Ultramax bulk carrier, Jabal Al Kawr. The brand-new coating technology was applied for the first time in the Middle East, and the second globally, on Minoa Marine’s MV Julia earlier this year at Asyad Drydock’s world-class facilities in Duqm, Oman, according to the company’s release.
Capitalizing on Asyad Drydock’s premium ship-servicing capabilities and state-of-the-art technologies, Asyad Shipping commissioned the application of the ecofriendly nano-epoxy silicone coating solution on its Ultramax bulk carrier, Jabal Al Kawr.

Exploring Epoxy Coating Failures with ExcelPlas
While epoxy coatings are generally durable and effective at preventing corrosion, there are a few common types of epoxy coating failures that can occur:
- Adhesion failure: This occurs when the epoxy coating fails to properly adhere to the surface of the pipe, which can be caused by factors such as improper surface preparation or a poorly formulated coating. Adhesion failure can result in the coating peeling or flaking off, exposing the underlying steel surface to corrosion.
- Blistering: This occurs when small bubbles or blisters form on the surface of the epoxy coating, which can be caused by improper surface preparation, moisture contamination, or excessive heat during curing.
- Cracking: This occurs when the epoxy coating develops small cracks, which can be caused by factors such as thermal expansion and contraction, improper coating thickness, or exposure to chemicals.
- Delamination: This occurs due to intercoat or interfacial adhesion failure due to the presence of a weak boundary layer such as silicone or hydrocarbon oil contamination.

Critical Questions for Protective Coatings for Asset Protection in Oil & Gas, LNG:
- Why is the coating not stopping corrosion?
- Why is the coating delaminating or blistering?
- Has the coating been correctly specified / applied?
- Does the coating meet the manufacturing standard, including properties such as correct hardness/cure, adhesion and thickness?
- What surface preparation and atmospheric conditions must be achieved to successfully apply the coating?
- Does the coating have any defects in it? How will these affect performance?
- Why did the coating fail? Root cause assessment.
- How can the coating be successfully repaired/remediated so that it doesn’t fail again?
ExcelPlas Labs can answer these questions and more…
