An NSRP-sponsored project investigating the cost of coatings QA suggested that current QA/QC processes have a high tendency to lead to conflict. Survey data collected during the project indicates that one in 20 inspection checkpoints is likely to result in a dispute. Some of these disputes may simply arise from the expected variability in standard coating QA test methods. Data regarding the reproducibility of coating QA measurements is generally not well understood and, in some cases non-existent. The paper will discuss the reproducibility of various measurements used in the industrial protective coatings industry.
Polysiloxane (often referred to as ‘hydide coatings’) products have been one of the major technology platforms used in the European offshore sector mainly due ban on isocynate among several customers. The potential long-term performance of polysiloxanes coatings have also been a strong argument for this topcoat selection in NORSOK (501 – rev 5) systems. There have been several claim-situations with delamination in epically two-coat systems, but similar problems have also been seen on traditional NORSOK systems.
