Interline 984: Extending Seawater Pump Lifespan in Norway

Proven protection through collaboration

In Norway, Interline® 984 from International® Protective Coatings is helping aquaculture operators combat corrosion and extend the life of seawater pumps. In partnership with Westing and Dalen Industriservice, the coating has delivered clear improvements in durability, repairability, and sustainability.
 

The challenge: corrosion and costly downtime

Seawater pumps on wellboats and fish farming facilities often face corrosion damage after just one or two years, leading to expensive replacements and operational delays. Frequent maintenance disrupts production and increases costs for operators across the aquaculture industry.

The solution: Interline 984 for long-term performance

After extensive testing, Westing and Dalen Industriservice selected Interline 984, a high-performance epoxy lining developed by International for harsh marine and industrial environments. Resistant to corrosion, acids, ozone, and aggressive cleaning agents, it provides long-term protection even under continuous seawater exposure.

“Interline 984 has proven to be extremely durable. The paint system can withstand everything from corrosion, acid and ozone to modern disinfection methods. It is smooth, easy to keep clean and retains its quality even after many years of use,” 
explains Fredrik Baade, Westing.

By repairing damage and reapplying Interline 984, Dalen Industriservice restores pumps to near-new condition, reducing waste and extending service life.
 

Results: Proven performance and savings

These benefits are now being seen across operations in Norway’s aquaculture sector.

The switch to Interline 984 has helped operators significantly cut maintenance costs and downtime. Instead of replacing pumps, they can refurbish existing ones for reuse, supporting both economic and environmental goals.

“The feedback from our customers is exclusively positive,” says Jøsokbakke.
“The collaboration between us and Westing means that customers get back a product that actually has a longer lifespan than when it was new.”

“For us, it is important to know our customers well, so that we can recommend the right solutions. Together with Dalen, we have found a method that works in practice, to the delight of both the supplier and the end customer,” 
says Fredrik Baade, Westing.

“The collaboration between us and Westing means that customers get back a product that actually has a longer lifespan than when it was new,”
