- Specialty joints can be supplied as part of turnkey riser packages for drilling/workover and production applications.
- Decades of experience in inspection and repair of riser joints is now translated into high-quality durable designs to withstand the harshest metocean conditions.
- Custom engineered for high-fatigue applications to withstand large bending moments along with maximum tensile-load capacity.
- Custom designed to optimize length, wall thickness, and envelope.
- In combination with supply of top and bottom connection systems, Oil States minimizes project interfaces to accelerate delivery schedules and reduce customer costs.
- Suitable for high-pressure drilling riser or production riser applications.
- Tapered stress joints can be supplied in steel or titanium for various rigid-production riser applications including TLPs and SPARs, free-standing hybrid risers (FSHRs), or for jack-up mobile offshore production units (MOPUs). Keel joints are designed for SPAR applications.
- Tapered stress joints can also be provided for high-pressure drilling as well as completion/workover applications. Optimal wall thickness helps to minimize cross-sectional stresses in the riser.
- Telescopic joints can be supplied for jack-up, semi-submersible or drillship drilling riser applications to provide tension compensation.
- Equipped to provide specialty riser joints incorporating a variety of connector types, riser materials and welding technology.
