Offshore Drilling Riser Pipe
Port Harcourt, Nigeria, West Africa

The project concerned drilling riser pipes used for offshore oil drilling operations subject to cycles of immersion underwater and storage on deck. Very tough environment and very tough life cycle (salt water, salt spray, sun, impacts, abrasion, and temperatures ranging from 40 to 250 degrees F). The original coating system, applied four years previous, had badly deteriorated.

The application main steps were:
• Sand blasting to SSPC-SP6
• Surface cleaning and chloride removal
• Two coats of Rust Grip®
• Two coats of Moist Metal Grip
• Two coats of Enamo Grip (white)
