The objectives of the study were to develop a protocol for testing protective coating performance on pitted SS, evaluate how various surface preparation methods affect the coating performance on pitted SS, and determine a reliable coating application procedure to cover the pits with a holiday-free film so the integrity of offshore pitted SS is improved.

The hydrophobic WR-Tech additive leads to stone wool, mandrel-wound pipe sections with significantly less water absorption relative to industry standards; faster drying rates; and durability over a wide range of potential CUI temperatures.

It is important to maintain inhibitor concentrations at a safe level in waters containing dissolved salts, particularly if these include chlorides.
