Custom, Cost-Effective Production Riser Connectors

The OPT ZF-2005™ is a patented and field-proven line of premium weld-on threaded connectors for production and drilling risers. The patented OPT ZF-2005™ is engineered specially to meet the demanding requirements of deepwater TLP and Spar production and drilling risers. “ZF” stands for zero-fatigue, and these connections have ultra-low stress amplification factors compatible with the stringent fatigue life requirements of production risers.

The OPT ZF-2005™ has been engineered, analyzed, and fully static and fatigue tested to assure compliance with API RP 2RP and ISO 13679. It has been used in production risers both throughout the entire riser string as well as in the highly-loaded locations in hybrid riser strings.
