Ultra Tolerant Coating Technology: The 15 Years Path From Maintenance to New Construction

Poor performance of materials…is why…more realistic application conditions are needed. An ultra-tolerant material, compatible with flash rust, humidity, poor profile and cold application conditions, potentially with Ultra High Pressure (UHP) water jetting, is presented in this paper.

Concepts for “maintenance coatings” “new construction” and “high durability” do not overlap in the offshore context. Maintenance coatings often do not aspire to “high durability” status while new construction processes aspiring to such status often fail to deliver such performance. The “high durability” aspiration still producesa divide between surface tolerant materials for maintenance operations and new construction coatings driving the adoption of different material types surface preparation methods and pre-qualification test protocols aimed at delivering an always illusive “high durability” performance. Facing this puzzle four questions may come to mind of an optimistic coating formulator or a demanding offshore asset owner: 1) can a surface tolerant maintenance coating deliver high durability despite the less favorable conditions in which is applied? 2) if that is possible could such tolerant coating technology be applied in a new construction context to improve the chances of a “high durability” outcome? 3) why? 4) how?The author’s answer to the first two question is 'yes' and this paper shares abundant supporting evidence of such statement. Evidence was built for the last 15 years after more than 15 million square meters of steel witnessing the testing selection application and real life performance of a specific surface and humidity tolerant coating technology in offshore projects ranging from maintenance to FPSO conversions and new construction. New data (not published before) is shared on tolerance to poor surface profile flash rust and damp & cold conditions. Independent costing data is publicly shared first hand on the impact associating this technology with UHP water jetting in conversion and new construction projects.The answers to “why” and “how” drive the conclusion of this paper. The poor performance of materials overly dependent on ultra careful surface preparation and application conditions in new construction is “why” tolerant solutions adapting to more realistic application conditions are needed. The combined use of an ultra tolerant material (compatible with flash rust humidity poor profile and cold application conditions) with UHP water jetting is presented as a possible answer to “how”.

Key words: coatings, surface tolerance, humidity tolerance, durability, offshore, maintenance, construction, epoxy, water-jetting, costing.
