Subsea pipeline integrity begins at the most critical points — the field joints. These connection areas require reliable, long-term corrosion protection to ensure continuous system performance in harsh offshore environments.
This installation showcases the application of the Allter Visco-Rite™ System for field joint coating (FJC) on a concrete weight coated (CWC) subsea pipeline. The project was executed onboard a pipeline laying vessel in the Gulf of Mexico for a Canadian asset owner, demonstrating the efficiency, reliability, and ease of applying visco-elastic corrosion protection systems in offshore conditions.
Efficient Surface Preparation with Bristle Blaster® Technology
Proper surface preparation is essential for ensuring optimal adhesion and long-term corrosion protection. For this installation, Bristle Blaster® technology was used to prepare the exposed steel at the field joint area.
This method delivers:
-
Surface preparation equivalent to abrasive blasting quality
-
Removal of corrosion, mill scale, and contaminants
-
Creation of an optimal anchor profile
-
Safe and efficient onsite preparation onboard installation vessels
Bristle Blaster® technology is ideally suited for offshore environments where controlled, efficient preparation is critical to maintaining installation schedules.
Allter Visco-Rite™ Field Joint Coating for Permanent Subsea Protection
Following surface preparation, the Allter Visco-Rite™ visco-elastic corrosion protection system was applied to seal the field joint area.
Allter Visco-Rite™ provides:
-
Immediate molecular adhesion without primers
-
Permanent visco-elastic flexibility
-
Complete sealing against water and oxygen ingress
-
Self-healing properties for long-term reliability
-
Proven performance in subsea environments
The system conforms seamlessly to complex geometries and provides a continuous corrosion protection barrier between the factory-applied concrete weight coating sections.
Engineered for Offshore Pipeline Integrity
Field joint coating is one of the most critical stages in offshore pipeline installation. Allter Visco-Rite™ systems ensure that corrosion protection remains continuous across the entire pipeline length, eliminating vulnerable points and extending service life.
This installation demonstrates how proven surface preparation methods and visco-elastic protection systems work together to deliver efficient, reliable, and long-term subsea corrosion protection.
