Nippon Steel Corporation (“Nippon Steel”) and Sumitomo Corporation have entered into a 10-year framework agreement with Shell Global Solutions International B.V. (“Shell”) for the global supply of oil country tubular goods (“OCTG”). A formal signing ceremony was held on October 14 in The Hague, Netherlands.

For over five decades, Nippon Steel and Sumitomo Corporation have been trusted suppliers of seamless OCTG products to Shell’s operating companies across more than 20 countries. This new agreement reflects this long history of collaboration and recognizes the comprehensive capabilities of both companies highlighting Nippon Steel’s consistent delivery of high-quality premium OCTG, alongside Sumitomo Corporation’s robust supply chain management services such as inventory control, maintenance and just-in-time delivery factored in this contracting decision.

This agreement reaffirms the commitment of all parties to ensure a secure and reliable supply of OCTG to support Shell’s global operations. Over the next decade, the partnership will focus on enhancing the value of the offering by expanding the product portfolio, optimizing supply chain efficiency, and leveraging digital technologies to improve traceability and transparency.

Nippon Steel and Sumitomo Corporation remain dedicated to deepening their strategic collaboration with Shell, contributing to the stable supply of energy and delivering long-term value to stakeholders.

Renewal of 10-Year Long-Term Agreement for OCTG Supply with Shell

Nippon Steel Corporation ("Nippon Steel") will participate in OTC (Offshore Technology Conference), scheduled to be held in Houston in the U.S. between May 6 (Mon.) and May 9 (Thur.). 
OTC is an exhibition where offshore-related companies and organizations gather from all around the world. It brings over 1,300 exhibiting companies and welcomes about 30,000 attendees each year. 
At this year's exhibitions, Nippon Steel will feature high-performance products such as high-end OCTG that can be used in high CO2 concentration environments, such as CCS*1, which is expected to be a major step toward achieving carbon neutrality; HYDREXEL™ (HRX19™), a stainless steel product for handling high-pressure hydrogen with advanced resistance to hydrogen embrittlement, which is required for commercial hydrogen stations for the hydrogen economy; and HTUFF™, a thick steel plate with enhanced HAZ toughness*2, which is used for offshore wind power generation equipment mounts and offshore structures. As the need for solutions for climate change increases worldwide, we will introduce our customers to energy-related products that are expected to serve as solutions for promoting decarbonization. 
Taking advantage of this exhibition event, Nippon Steel will broadly contribute to achieving a carbon neutral society in the areas of technological development and product offerings by responding to the needs for decarbonization of energy companies around the world, aiming for the goals of Nippon Steel's "Carbon Neutral Vision 2050." 
The Nippon Steel Group will continue to pursue the world's best technology and manufacturing capabilities, and contribute to improving society through activities that conform to the Sustainable Development Goals (SDGs) adopted by the United Nations, with a focus on “Affordable and Clean Energy” and “Climate Action.” 
*1: What is CCS (Carbon dioxide Capture and Storage)? 
Carbon dioxide capture and storage technology that collects CO2 emitted from power plants, chemical plants, etc. after isolating it from other gases and then stores and injects it deep underground. 
*2: What is HAZ toughness? 
The toughness of parts where the metallographic structure changes due to thermal effects during welding.

Participation in OTC, an Energy-Related Exhibition in the U.S.

<a name="_Hlk162423098" id="_Hlk162423098">Dr Hisashi Amaya</a>, a member of the Tubular Products Technical Service &amp; Solution Dept., Tubular Products Technology Div., Nippon Steel Corporation, has been awarded the 2024 AMPP Fellow Honor Award by the Association for Materials Protection and Performance (AMPP)* in the USA. The award was presented in recognition of his contribution to the development of Corrosion Resistance Alloys (CRAs) -for the energy sector, including oil and gas development, as well as his many years of significant contribution to the testing method standard setting committee and the administration of the society. The award ceremony was held in New Orleans, USA, on 6 March 2024 in conjunction with the AMPP 2024 Conference &amp; Expo.

*: The Association for Materials Protection and Performance (AMPP) is a non-profit organization formed in 2021 through the merger of NACE International (founded in 1943, headquartered in Houston, Texas) and SSPC: The Society for Protective Coatings (founded in 1950, headquartered in Pittsburgh, Pennsylvania). AMPP serves as a global community of over 54,000 individual members across 130+ countries, comprising engineers and professionals dedicated to materials corrosion prevention and protection.

The Fellow Honor Award, which has been awarded this time, recognizes significant contributions in the field of materials protection and performance. It acknowledges academic, leadership, technical, and policy efforts related to the protection and performance of materials. Within the association, Fellows are established as technical and professional leaders who serve as advisors, fostering a broad network of relationships across the industry. This prestigious award has been bestowed upon renowned university professors, independent research institution scholars, and key materials technologists from major oil companies in the past.

Throughout his career, Dr Hisashi Amaya has made significant contributions to the understanding of corrosion phenomena in hostile oil and gas production environments. He has been instrumental in developing materials tailored to these specific environments contributing to safe and stable energy production.

Furthermore, he has been an active member of the ANSI-NACE MR0175/ISO 15156 standard development and maintenance committee. This standard is globally referenced and provides material recommendations for use in oil and gas production environments containing H2S. Over the years, he has also contributed to the technical symposium sessions at the association’s annual meetings and served as a member of the committee responsible for developing testing method standards, furthering the association’s activities.

Dr. Amaya received the 2024 AMPP Fellow Honor Award

Nippon Steel has developed SM-140MS, a proprietary material for Ultra High Strength and Mildly Sour applications. This cutting edge and unprecedented performance was achieved by integrating Nippon Steel lessons learned through its lengthy experience in manufacturing high strength sour service materials combined with stringent control of key manufacturing variables such as chemical composition, melting, rolling and heat treatment.

SM-140MS is a low alloy High Strength Carbon steel OCTG material (Yield Strength ranges from 140ksi to 150ksi), suitable for Mildly Sour Service  applications. SM-140MS is Sulfide Stress Cracking (SSC) resistant suitable for NACE region 1 and part of region 2. Additional SSC Characterization is ongoing to extend its application domain further. As such SM-140MS is the Casing material of choice for Ultra HPHT applications where presence of H2S trace is expected. SM-140MS is manufactured under a stringent quality control in compliance with API 5CT and each heat is SSC tested, as Quality Control, per NACE TM0177 method A, solution B (pH3.5) with 0.01 bar H2S, using an applied stress of 85% SMYS. 

Keeping up with Nippon Steel historic pioneer leadership in developing high performance sour service materials such as 95, 110, 125 grades, , we continue pushing the limits of material technology and remain at the forefront of innovation with products that safely satisfy customer’s challenging environments.SM140 MS performances will be presented at AMPP conference 2024.
