Azko Nobel’s Intertherm 228 Coating Allegedly Caused Degradation and Discoloration to the Ichthys LNG Pipes After Use

Interview with Executive Vice President and COO at Hempel on a  “A Very Competitive Market”

Hempel Reports 2022 Financial Results
The company delivered organic revenue growth of 12.7% in 2022, and revenue of €2,159 million. Compared to 2021, this represents an increase of €415 million, driven by increased sales prices and acquisitions. The company reports its 2023 outlook is mid to high single-digit organic revenue growth and an increasing EBITDA margin, leading to an EBITDA in the range of €260-290 million.
In 2022, Hempel emphasized its focus on improving earnings by reducing costs to compensate for rising raw material costs and lower volumes. Despite very challenging market conditions, Hempel delivered a total growth of 23.8% for the year. Adjusted EBITDA was €257 million, an increase of €52 million versus 2021, and the adjusted EBITDA margin was 12% in 2022.


Hempel joins Global Industry Alliance
Coatings company Hempel has increased its commitment to supporting the maritime industry’s shift to ever-more sustainable operations by joining the Global Industry Alliance (GIA) for Marine Biosafety to support shipping’s emissions reduction pathway and to mitigate against the spread of invasive species

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?

This newsletter is brought to you by ExcelPlas Coating Labs (http://www.excelplas.com/)

ExcelPlas Labs provides independent testing, analysis, and investigation on protective coatings to prevent corrosion.

ExcelPlas has extensive analytical capabilities for testing of Protective Coatings and Insulation Consulting for major oil and gas companies.

We conduct corrosion surveys, coating sampling, coating analysis, and testing to ensure coating specifications for a wide range of onshore and offshore clients in Australia and the Asia-Pacific Region.

ExcelPlas Labs offer a full range of coating testing and analytical services to Australia’s mining, oil, gas, and infrastructure sectors.

Forensic analysis for undertaking various coating-based failure investigations and problem-solving.

ExcelPlas Undertakes Analysis & Testing of Polymer Coating Systems including:

  • Epoxy Protective Coatings
  • Epoxy-Phenolic Protective Coatings
  • Fusion bonded epoxy (FBE) 
  • Dual-Layer Fusion bonded epoxy (DLFBE)
  • Liquid applied epoxy (LAE)
  • Abrasion-resistant overcoat (ARO)
  • Three-layer PE (3LPE)
  • Multi-component liquid spray  (MCL)
  • Heat shrink sleeves (HSS)

Testing on Coatings that ExcelPlas can Undertake includes:
