🔧 Reinforcing Fire Suppression Pipes on a Mega Yacht

With Spray-In-Place Epoxy Technology


🚨 The Challenge

On board this luxury mega yacht, seawater is pumped through custom-fabricated 80mm (3″) and 100mm (4″) steel fire suppression pipes to feed hydrants throughout the ship.

After years of service, saltwater corrosion began to create pinhole leaks, threatening the yacht’s interior. These pipes run hidden behind walls, beneath floors, and under heavy equipment—making replacement a logistical nightmare.

Replacing even a single section meant:
❌ Tearing apart hand-crafted interiors
❌ Custom re-fabricating pipe segments
❌ Extensive downtime and sky-high costs


✅ The Smart Solution

Working closely with the ship’s engineers, we developed a non-invasive internal pipe rehabilitation plan.

🔹 System Drained & Accessed
Strategic entry points were created throughout the ship to reach critical piping.

🔹 Precision Cleaning
Our specialized tools prepped the inner steel walls to a paint-ready finish—even through complex bends.

🔹 Dual Repair Approach

  • Epoxy Liners were installed in straight, accessible pipe sections

  • Spray-In-Place Epoxy was applied beyond multiple 90° bends using advanced small-diameter spray heads

This seamless epoxy barrier fully isolated the steel from saltwater—halting corrosion and sealing pinholes without disrupting the interior.


🛠️ The Results

Thanks to our advanced technology, we:

  • Eliminated the need for demolition

  • Avoided custom pipe re-fabrication

  • Restored full system integrity

  • Saved the client thousands in potential interior repairs

“Using spray epoxy saved us from dismantling the yacht piece by piece—this approach was a total game changer.”
— Chief Engineer, Mega Yacht Project


💡 Why Spray Epoxy?

Spray-in-place epoxy coating is ideal for hard-to-reach, curved, or concealed pipe systems where traditional lining fails.

🔧 Perfect for:

  • Fire suppression systems

  • Pool/spa piping

  • Drain and sewer lines

  • HVAC condensate pipes

  • Commercial & marine water systems
