Riser Hang-Off Collar for Installation Without Pipe Disassembly
The Split-Type Riser Hang-Off Collar is engineered to revolutionize deepwater riser installation. By replacing traditional integral designs with our innovative two-piece forged steel assembly, we provide a robust, load-bearing solution that minimizes operational downtime while meeting the most rigorous international safety standards.
Why Our Riser Hang-Off Collar Eliminates Downtime
Traditional riser hang-off systems often require the complete disassembly of riser strings, leading to significant offshore operational delays and increased safety risks. Our split-type design eliminates these bottlenecks:
Rapid Installation: Install directly around the riser without string disassembly, reducing project downtime by up to 70%.
Diver Safety: The design significantly minimizes the need for high-risk underwater diver intervention.
Operational Efficiency: Drastically reduces total offshore days, optimizing project budgets in ultra-deepwater environments.
Key Technical Highlights of Riser Hang-Off Collar
Load-Bearing Performance: Engineered for ultra-deepwater operations, supporting riser strings in depths of up to 1,780 meters.
Engineering Compliance: Fully validated against global industry standards, including API 16Q, ISO 13628-7, and DNV-ST-F201.
Durability & Precision: Features precision-machined sealing and stress-relief profiles to resist seawater erosion and fatigue.
Versatility: Compatible with drilling, production, and steel lazy-wave risers.
