Assessment of Suitability of Coating Systems for Subsea Systems

Abstract

A comprehension of the variables that assist with the actualization of good adhesion is of vast scientific and technological significance in order to gain control over the phenomenon of adhesion. To improve protection, operators should commence with the critical analysis of the materials to be deployed and their suitability for the site/field specific conditions. Till date, there are relatively few reported studies relating to coating functional chemistry, mechanical properties and performance. This paper thus evaluated in-depth, the different types of coating materials with respect to their suitability for subsea operations and identified the best practices to expand the life of coatings, and coated structures. The assessment of the economic and technical problems of coating materials, their application, and their service behavior for subsea/deepwater operations have been conducted using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). From the TOPSIS analysis, the best coating material considering the several criteria including: durability, resistance to stress, strength, adhesion, ductility, compatibility with cathodic protection and cost is Organic Coating which scored 0.653 followed by Nickel Alloy, with a value of 0.623 and the third best is Non-Ferrous Alloys.
