The Curse of the Mummy: Mysterious Tank Lining Failures in WAC Vessels

by Mike O’Donoghue, Ph.D., Vijay Datta, M.S., and Sean Adlem, International Paint LLC.; Jack Whittaker, Cenovus Energy Inc.; Doug Wade, NWS Inspection Ltd.; and Margaret Pardy, Mag Consulting Inc.

In this article, the authors outline discoveries made from forensic work to unravel epoxy lining failures in several water treatment weak acid cation (WAC) vessels.


Induction Heating for Cold Weather Preheating and Post-Curing Of Liquid Epoxy Coatings On Gas Pipeline Girth Welds

by Bruce J. Wiskel, P.E., Pacific Gas & Electric Company; and J. Peter Ault, P.E., Elzly Technology Corporation

The authors discuss the challenges of applying coatings to transmission pipeline when the surface temperature dips below 50 F and determine that the optimum approach for cold weather coating application on girth welds is to use the existing approved epoxy coatings with induction preheat of the pipe during surface preparation, coating application and cure.


Bad Vibes: Using Coatings to Eliminate Vortex-Induced Vibration of Riser Strings on Deep-Water Offshore Structures

by Peter Bock

When the length of the riser piping on an oil production platform increases for structures in deep water, vortex-induced vibrations can crack joints in the riser string or rupture the riser pipe itself, causing a potentially disastrous oil spill. The author describes a project where coatings provided a preventative solution.


Development of Materials and Process Metrics for High-Performance Abrasive Blast Surface Preparation

by Robert Kogler and Laura Erickson, Rampart LLC

The authors describe ongoing work being conducted with the Center for Corrosion Science and Engineering and the U.S. Naval Research Laboratory, with the support of the Naval Sea Systems Command, in order to understand and refine variations in surface preparation and their effect on the subsequent performance of marine coatings.
