An Introduction to NORSOK M-710: Ensuring Material Quality & Reliability in the Oil and Gas Industry
Updated: Jul 26, 2024
NORSOK M-710 is a standard developed by the Norwegian petroleum industry for the selection and use of materials in offshore and marine environments. The standard provides guidelines for the selection of materials that can withstand harsh environmental conditions and ensure the safety of personnel and equipment. In this blog, we will explore the importance of NORSOK M-710 and its impact on the offshore and marine industries.
What is NORSOK M-710?
NORSOK M-710 is a standard developed by the Norwegian petroleum industry for the selection and use of materials in offshore and marine environments. The standard provides guidelines for the selection of materials that can withstand harsh environmental conditions, such as high temperatures, pressure, and exposure to saltwater.
NORSOK M-710 covers a wide range of materials, including metals, polymers, rubbers, plastics, and composites, and provides guidance on their selection, testing, and use in offshore and marine environments. The standard also includes requirements for corrosion protection, welding, and non-destructive testing to ensure the integrity and safety of offshore and marine structures.
In the case of elastomeric materials, O-rings, gaskets, and molded rubber parts, NORSOK M-710 is frequently used to prove a material's resistance to explosive decompression. In extremely high pressure applications, gasses can begin to permeate elastomeric materials. These gasses can saturate the material, filling any available molecular voids. When the pressure of the application decreases, the gas naturally flows out of the elastomeric material over time. Depending on the shape of the gas molecule, the penetration and subsequent removal of the gas may occur at different rates. If the pressure decreases too quickly, the elastomeric material can experience explosive decompression.
Explosive decompression is a sudden and violent release of gas from a high-pressure environment that can cause severe damage to equipment and endanger personnel. When a pressurized gas is released rapidly, it can cause the gas to expand and create small voids or bubbles within the seal. If the pressure is released too quickly, these bubbles can expand rapidly, causing the seal to rupture or explode. This can result in equipment failure, damage, and even injury or death. Explosive decompression is most common with carbon dioxide gas due to its common use and molecular shape.

Why is NORSOK M-710 important?
NORSOK M-710 is important because it ensures the safety of personnel and equipment in offshore and marine environments. These environments are subjected to harsh conditions, including high temperatures, pressure, and exposure to saltwater, which can cause significant damage to materials and structures over time.
The use of materials that are not suitable for these environments can result in the failure of equipment, which can lead to accidents and injuries. NORSOK M-710 ensures that materials used in offshore and marine environments are selected based on their ability to withstand these conditions and maintain their integrity over time.
Impact on the Offshore and Marine Industries
NORSOK M-710 has had a significant impact on the offshore and marine industries. The standard has helped to improve the safety of personnel and equipment in these environments by providing guidelines for the selection and use of materials that can withstand harsh environmental conditions.
Compliance with NORSOK M-710 is a requirement for companies operating in the Norwegian petroleum industry, as well as many other companies operating in offshore and marine environments worldwide. The standard has also been adopted by other industries, such as the aerospace industry, where materials must withstand harsh environmental conditions.
Conclusion
In conclusion, NORSOK M-710 is a critical standard for the selection and use of materials in offshore and marine environments. The standard provides guidelines for the selection of materials that can withstand harsh environmental conditions, ensuring the safety of personnel and equipment in these environments. Compliance with NORSOK M-710 is a requirement for companies operating in the Norwegian petroleum industry, as well as many other industries operating in offshore and marine environments worldwide. The standard has had a significant impact on improving the safety and reliability of structures and equipment in these environments.
