Stopaq Offshore Success: Re-Sealing the Angel Platform Roof in Australia

 

In 2012, Stopaq had the opportunity to take on a challenging offshore project quite literally “down under” — re-sealing the roof of the Angel offshore platform off the coast of Australia.

Offshore environments are never forgiving. Constant UV exposure, salt-laden air, temperature swings, and moisture intrusion combine to accelerate coating breakdown. In this case, the existing coating system had degraded much faster than anticipated due to the particularly harsh offshore conditions.

The client needed more than just a replacement coating. They needed a system that could truly withstand the environment long term.

For this project, several critical boxes had to be checked:

• Flexibility to accommodate movement and structural shifts

• High resistance to chlorides to prevent blistering commonly seen with traditional paint systems

• Tolerance to significant temperature fluctuations

• Extended UV resistance under constant sun exposure

Traditional coatings often struggle in one or more of these areas — especially when it comes to chloride resistance and long-term UV stability in offshore environments.

The Stopaq Solution: A Two-Component System

The approved system utilized:

• Stopaq Wrappingband EZ

• Stopaq Topcoat

Stopaq Wrappingband EZ

Wrappingband EZ delivered a simple, highly effective sealing solution with several key advantages:

• Minimal surface preparation required

• Wide application window for installers

• Immediate watertight sealing

• Maintains flexibility and structural integrity for foot traffic and movement

In offshore applications, ease of application is not just a convenience — it reduces labor exposure time and improves consistency. Wrappingband EZ created a durable, flexible barrier that addressed moisture intrusion at its source.

 To ensure long-term UV performance, Stopaq Topcoat was applied directly over the Wrappingband EZ.

This added UV-resistant protective layer ensured the system could withstand prolonged sun exposure without degradation — a critical factor for roof applications in offshore Australia.

The Result: All Boxes Checked

Once again, a Stopaq system provided a tailored solution that met every requirement:

• Flexibility

• Chloride resistance

• Temperature durability

• UV protection

Offshore projects demand systems that perform under relentless environmental stress. In this case, Stopaq delivered a proven, practical solution designed for exactly those conditions.

When the environment is at its harshest, having the right system in place makes all the difference.

Self-Healing Stopaq

 

What “Self-Healing” Really Means in the World of Stopaq

If you’ve spent any time around modern corrosion prevention technologies, you’ve probably heard the phrase “Stopaq is self-healing.” But what does that actually mean in real-world conditions? We recently put it to the test in our shop—and the results were impressive.

A couple of weeks ago, we were experimenting with some Wrappingband on pipe sections that were extremely dirty. (That part isn’t central to this post, but trust me—another write-up is coming that will show just how well Stopaq bonds even when the substrate is far from ideal.) For this test, instead of using the standard Outerwrap PE, we capped the system with a Covalence heat-shrink sleeve.

Once everything cooled, we made a few cuts to see how the system behaved. These were very basic peel tests, and—no surprise—there was full cohesive failure, even though the pipe surface was in awful shape. But here’s what really stood out: the amount of Stopaq Wrappingband that oozed out of the cut. It pushed its way into the opening immediately, exactly as a self-sealing visco-elastic coating should. It was one of those “wow” moments that perfectly demonstrates the material’s nature.

Then we took things further. Using a hammer and a screwdriver, we intentionally damaged the coating system all the way down to bare steel. And within just a few hours, the Stopaq material had already flowed back in, filling and sealing the area that was much larger than a typical pinhole.

That’s the essence of self-healing:
When Stopaq is damaged—during backfill, by a careless worker, by debris, or even by a stray rock kicked up by equipment—it doesn’t wait for someone to come fix it. The material migrates, fills, wets, and reseals the vulnerable area before anyone even knows there was a problem.

This is one of the biggest reasons asset owners trust visco-elastic technology. It delivers long-term protection, even in the messy, unpredictable conditions of real job sites.
