At DEAN, we utilize a variety of caisson configurations to provide safe, controlled, and dry work environments in locations that would otherwise be difficult—or nearly impossible—to access.
From inland marshes to coastal waters, our caisson systems enable efficient pipeline inspection and repair while minimizing environmental impact. These specialized solutions allow our crews to safely perform critical maintenance in challenging conditions without compromising quality or safety.
Today, we're highlighting our Deepwater Caisson System, designed to provide dry access to subsea pipelines in water depths of up to 36 feet. This system creates a controlled work environment for a wide range of repair activities, including:
✔️ Blasting and coating
✔️ Sleeve installations
✔️ Pipeline cut-outs and replacements
✔️ Inspections and integrity assessments
✔️ Additional maintenance and repair services
The Deepwater Caisson can be installed on pipelines up to 30 inches in diameter and offers multiple configuration options to accommodate longer inspection and repair scopes.
No matter how challenging the environment, DEAN has the expertise, equipment, and innovative solutions to make pipeline repairs safer, drier, and more efficient.
It’s a capability that continues to separate our Gulf Coast team in the field.
