The rising use of exhaust scrubber systems across maritime fleets has led to a hidden problem: severe corrosion of mild‑steel scrubber pipes, outlets, diffusers, recycle tanks, and surrounding hull areas. Without adequate protection, acidic washwater can penetrate weld seams or hull plating, resulting in water ingress into engine rooms, ballast tanks, and cargo holds—with costly operational consequences.
Highly corrosive wastewater in open‑loop scrubbers can erode unprotected steel within months, especially near overboard pipes and outlet zones.
Given the danger and the expense of unscheduled drydock repairs, proactive, permanent protection is paramount for scrubber reliability.
Ecospeed: Engineered for scrubber protection
- Chemically resistant and durable
Ecospeed can resist aggressive acid and alkali exposure from scrubber washwater. Case studies show that if the coating is applied inside pipes, outlets, diffusers, and recycle tanks it can withstand continuous exposure for years with no visible degradation.
One shipyard supervisor described Ecospeed’s condition after two years as, “still in excellent condition” and “looking fresh after cleaning.”
- Lifetime coverage with no recoat required
Once applied, Ecospeed remains intact for the vessel’s entire lifespan. No recoats are necessary during future dockings, saving operators significant time and operational expense. Overcoating intervals can be as short as three hours, enabling fast turnaround during application.
- Repairs underway, without drydock
When corrosion has already set in, Hydrex (Subsea Industries’ sister company) can replace corroded pipe sections on vessels at anchor or quayside, then apply Ecospeed either before or after welding. This avoids costly drydock visits and extended downtime.
- Proactive protection prevents leak emergencies
Even before corrosion becomes visible, replacement pipes coated with Ecospeed can be installed proactively. This preventive approach keeps ships operational without unexpected failures or emergency repairs.
Conclusion
Ecospeed delivers proven, robust protection in one comprehensive coating system tailored to withstand the chemical, thermal, and mechanical challenges of scrubber installations. Its long-term durability eliminates repaint cycles. Add its on-site application and repair flexibility, and Ecospeed becomes the intelligent choice for operators who must safeguard scrubber pipes, outlets, and tanks against corrosion and unplanned operational disruption.
