The NSRP Surface Preparation and Coatings panel sponsored a project to reduce the extent of abrasive blasting to remove aged, ultra-high solids coatings from tanks and other spaces on Navy ships. This “partial blast” process allows a percentage of remaining serviceable Ultra High Solids (UHS) to remain. After surface preparation, a single coat application of UHS coating is applied to all surfaces.
The NSRP Surface Preparation and Coatings panel sponsored a project to reduce the extent of abrasive blasting to remove aged, ultra-high solids coatings from tanks and other spaces on Navy ships. This “partial blast” process allows a percentage of remaining serviceable Ultra High Solids (UHS) to remain. After surface preparation, a single coat application of UHS coating is applied to all surfaces. During this project, partial blast surface preparation of ultra-high solids epoxy coatings was observed on two projects. Consistent cost savings has been demonstrated in both demonstrations. The work has shown that partial blast can be effectively performed at a reduced cost. Cost savings result from a reduction in abrasive blasting time and fewer clean-up-inspect rework iterations. Though there is limited data and demonstrations to-date, there have not been any signs of catastrophic impacts to service life; further service time, field observations, and testing will help to build confidence that the alternative process reduces cost at an acceptable performance risk.
Fourteen countries, 20 states, and 76 bases…that sounds like quite a deployment! But what if, instead, you are charged with the evaluation and maintenance of over 500 water-storage tanks and related structures on those bases. Who would you turn to for professional guidance? How would you keep all of the details of the structures’ conditions and recommendations for maintenance organized in a manner that would allow you to rate and prioritize tank maintenance requirements?

A device measuring solution resistance across a gold interdigitated electrode, surface temperature and relative humidity, dynamically monitors environmental parameters on board a naval ship over the period of 9 months. Rigorous statistical analysis is used to analyze solution resistance data.
This a basic profile to help in making a decision if getting into the Military coating business is good for you.
