Oil States Highlights Deepsea Mineral Riser System Project

ARLINGTON, TX: May 25, 2021 – Oil States Industries, Inc. (OSI) is very pleased to confirm that the company was selected in the first quarter of 2021 by Allseas to supply a Deepsea Minerals Riser System for their deepsea nodule collection vessel, the Hidden Gem.


The project includes the design and manufacture of a deepwater riser system to collect polymetallic nodules in the extremely remote Pacific Ocean Clarion Clipperton Zone.  These nodules contain high concentrations of minerals utilized in electric vehicle batteries, solar panels, and other systems which support the energy transition.


RiserTec™, an independent division of OSI, performed the system engineering and global riser analysis (GRA). RiserTec has extensive experience with deepwater riser system engineering and analysis and has designed systems for some of the world’s harshest environments.  “We are pleased to have met the challenge of designing a system capable of reaching the extreme water depth of 6,000 meters, which is 2,000 meters beyond the reach of conventional oil and gas riser systems,” noted Dr. John Shanks, Principal Engineer, RiserTec.


The remote nature of the worksite demands new levels of equipment safety, reliability, and performance.  OSI’s field-proven, industry-leading Merlin™ connection system is at the core of this system.  Unlike many other connector systems, Merlin connections have no moving parts.  They offer a robust, reliable, fast make-up system that enables reaching ultra-deepwater depths safer and faster than conventional riser systems.


Oil States Industries’ Vice President, UK and Asia, Garry Stephen, commented, “We thank Allseas for their confidence in OSI’s products and services.  We look forward to delivering the system and providing support to ensure Allseas’ project is a resounding success.”


OSI has also recently been honored as a winner of the 2021 Offshore Technology Conference’s Spotlight on New Technology® Award for its Merlin™ Deepsea Mineral Riser System. This award recognizes OSI for its technological advances in support of the developing deepsea minerals industry.
