|Deepwater Capital Equipment Provider
Oil States Industries has provided innovative technologies and industry-changing advancements for more than six decades. We are a worldwide leader in developing and providing flexible bearings and connectors for the most advanced floating and subsea structures, including drilling rigs, subsea pipelines and production platforms. We pioneered the modern methods for installing and leveling fixed platforms that are primarily used today, and we developed the technology that has become the connector of choice for platform tethers, conductor casing, risers and subsea pipelines. We primarily manufacture our products in Arlington, Houston and Lampasas, Texas; Tulsa, Oklahoma; Houma, Louisiana and Aberdeen, Scotland. We have additional sales and service locations in Brazil, France, Nigeria, Norway, Singapore, Thailand and Vietnam.

|Production Platform Products |
We manufacture, supply and service connectors and cranes for floating deepwater production platforms including tension leg platforms (TLP's), floating production storage and offloading vessels (FPSO's), and SPAR's. Our connector products facilitate the production and export processes on the platform and, in the case of TLP's, help moor the platform to the seabed. Our connector products, including the FlexJoint® and Merlin connectors, are well accepted solutions in the industry and are semi-proprietary. In addition to connectors, we provide light-duty platform cranes under the brand names Nautilus and SMATCO. We have one of the largest installed bases of any OEM in the offshore oilfield service industry.
Our FlexJoints are installed on production and export risers in floating production platforms. The increase in deepwater production has increased the demand for steel catenary risers (SCR) to transport the hydrocarbons (1) from the subsea wellheads to the production facility and (2) from the facility to the export pipelines. Manufactured from a combination of forged steel and elastomeric elements, our SCR FlexJoint reduces the motion-induced stresses between a floating offshore facility and the riser. FlexJoints are capable of providing a free angular rotation ±20°, pressures up to 10,000 psi and axial tensions up to 3,500 kips.
Our Merlin and TLE connectors improve the efficiency of installing TLP mooring connectors by limiting the number of offshore welds necessary to install the risers. Commercialized in 1991 with the installation on the Exxon Augur platform, the Merlin TLE connector was the first developed non-rotational connector for use in anchor tendons of TLP's. With circumferential teeth rather than a helical threads, the Merlin connector is made-up and broken out by separating the teeth using hydraulic pressure. The use of Merlin connectors provides for installation efficiencies as the make-up time for Merlin connectors is a fraction of the time necessary to weld tendons or pipe offshore.
Through our manufacturing facility in Houston, we manufacture pipeline equipment, allowing for the installation, expansion or repair of subsea pipelines. Our installation products include pipeline tie-in sleds, jumpers, collet connectors, remote articulating connectors and pipeline end manifolds. These products allow for the transport of hydrocarbons from the wellhead to the pipeline or floating production facility. The mid-line tie-in sled allows for the future expansion of the pipeline to include the production of a future nearby field. As the pipelines around the world have increased in depth, we have advanced our product line to operate in a diverless environment.
We are also a leading manufacturer of subsea pipeline repair equipment. Our HydroClamp product provides operators with a metal on metal seal to repair a leaking or damaged pipeline. In addition, we are a leading provider of HydroTap manufacturer; the HydroTap allows for the expansion of an existing pipeline without taking the current pipeline production out of service.

|Drilling Rig Products |
Through our Houston, Texas and Houma, Louisiana facilities, we provide several products for installation on floating drilling rigs. Our product line includes semi-submersible rig mooring systems and winches and drilling riser FlexJoints. We also integrate blow-out preventer (BOP) systems and controls and fabricate coiled tubing and BOP lifting frames. Through our Brazil and UK locations, we provide drilling riser repair and storage services.
Our Oil States Industries subsidiary also produces elastomer products and connector products used in the defense and aerospace industries.
