ADVANCED DRILLING TECHNOLOGIES AND SERVICES ENABLE
THE HIGHEST LEVEL OF SAFETY, SPEED, ECONOMY AND PERFORMANCE
As the specialists in all OEM riser systems, we deliver higher performance for both existing assets and newbuild technologies that enable more wells drilled in less time; lighter, faster and safer riser make up; and the removal of HSE risk factors for on-rig personnel. We deliver unparalleled service and support to recertify any OEM equipment or to provide OSI CertifiedTM warranty backing as CEM.
Industry Challenges
Offshore drillers face a range of technical challenges whether in shallow water and deepwater drilling from demanding pressure, temperature, sour-service, or depth requirements to navigating narrow pressure windows. Ensuring the safety of rig personnel safety remains at the forefront. At the same time, many drillers are also emerging from a series of challenging economic conditions and looking to accelerate into the next upcycle.
Cost-effective reactivation of previously cold-stacked assets with condition-based maintenance, ensuring of integrity of pressure-control equipment and adherence to class standards are key alongside the economic concerns driving a need for increased efficiency, performance, and speed of drilling operations. Future safety improvements such as complete removal of personnel from the red zone, automation of equipment, optimization of rig lifting operations, effective riser gas handling, and robust equipment qualification for 15k, 20k or sour service all require technological advancements.

MERLIN™ CONNECTORS
SETTING THE STANDARD KEYSTONE OF PERFORMANCE
Connections for All Pressures
Oil States Drilling Riser Systems include Merlin™ Connectors. With over 400,000 connections in the field, Merlin™ Connectors have consistently proven to be at the forefront of connector technology worldwide. The connectors are designed and manufactured to meet a range of high load cases including axial, bending, compression, and internal pressures up to 15K psi for the most extreme environments.
Greater Reliability, Enhanced Safety
Merlin™ Connectors have fewer failure points and demonstrate superior fatigue-resistance compared to conventional connections which provides greater reliability and safety. The unique design geometry of the connection, which includes interlocking teeth rather than threads, means that the connector pin and box can only be mated in one precise configuration, ensures confirmed make-up, and provides superior pre-loaded strength with dual metal-to-metal seals.
Merlin™ connectors require no bolts, eliminating safety risks related to bolt-handling, bolt integrity and costly maintenance of spares. Merlin™ systems can be provided with full automated, hands-free connection make-up with OSI’s riser spider system with demonstrated connector make-up under 40 seconds.
