ExcelPlas Labs Coating Condition Survey (CCS) for Oil & Gas and LNG Clients
The condition survey provides advice on urgent coating related challenges and creates the foundation for future maintenance planning by advising on causes of possible failure and provides a maintenance coating specification.
A Coating Condition Survey can extend plant operational uptime, reduce long-term maintenance costs and prevent lost revenue. An ExcelPlas Labs coating expert will conduct a survey evaluating the condition of the existing coating system and underlying steel structure.
ExcelPlas Labs Coating Condition Survey (CCS) provides the following information:

  • Digital Imaging Inspection (DII) with special incident lighting on the actual condition of the existing coating system including colour shade of the coating.
  • Evaluating the type and percentage of defect (example in accordance to ISO 4628-1/5) per main area on the structure and determine the possible cause(s) of failure.
  • Evaluating and investigating which environmental factors the coating may have been exposed to, the duration and the effect on coating integrity/service life.
  • Checking and reporting dry film thickness (DFT) measurements using statistical grid testing.
  • Checking the adhesion/cohesion of the system and report according to ASTM D 3359 (cross-cut test), ISO 16276-2, ASTM D6677 (x-cut test) or the ASTM D4541 Pull-off Test.
  • Discontinuity (pinhole) testing and report according to NACE SP 0188/ISO 29601.
  • Embedding and Polishing Paint Chips in Epoxy setting compound followed by Scanning Optical Microscopy (SOM) to give a high-resolution image of the full cross-section of the coating highlighting voids, inter-coat delamination, encapsulated rust layers, poor barrier pigment dispersion, microcracks, etc. 
  • If the generic paint type is unknown, ExcelPlas Labs will determine the paint type using the FTIR spectral analysis.

All inspections and findings are comprehensively and clearly documented with high resolution photograph along with recommendations on what type of maintenance/repair is needed and when.


Failure Analysis and Investigation of Protective Coatings in Mining, Marine Offshore Oil & Gas Chemical Plants, Energy Infrastructure and Bridges (Ask the Experts)

This newsletter is brought to you by ExcelPlas Coating Labs (

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:

  • Coating identification by Infra-red Analysis (FTIR)
  • Degree of Cure by Thermal Analysis (DSC)
  • Coating Filler Identification by X-ray Analysis (EDS/XRD)
  • Coating Microstructure by Embedding, Polishing and Optical Microscopy (OM)
  • Coating Thermal Stability and Composition by Thermogravimetric Analysis (TGA)

DSC – Phase transition/volatiles / Tg / degree of cure/characterisation
TGA – Volatile compounds, inorganic mass % mix ratio
Element mapping for chlorides on paint flakes
Microscopy -Count layers and thickness of layers

  • Assess porosity and voids
  • Check distribution and orientation of filler particles

Condition monitoring and analysis of corrosion prevention coatings (epoxies, epoxy-phenolics)

Testing of Epoxy Coatings (LAE, FJC, FBE), heat shrink sleeves and tapes, barrier tapes and meshes.
