    N’GENIUS Solution on Horizon for Oil, Gas, and LNG Industry

    An innovative range of high-strength austenitic stainless steel has been developed that will revolutionize the design and construction of onshore and offshore facilities in the oil, gas, and liquefied natural gas (LNG) sector.

    The global demand for LNG is projected to reach 700 million tonnes per year by 2040 fuelling the need for greater LNG infrastructure including import-receiving and export terminals, FLNG vessels, and LNG carriers. Since these facilities are being designed with larger capacities and operating under increasingly more challenging conditions, advanced materials technology is required to maximize performance, reduce carbon emissions and optimize through-life costs. Fortunately, a N’GENIUS solution is on the horizon.

    Patent-protected in 30 countries around the world, the N’GENIUS Series is a complete ‘family’ of high-strength austenitic stainless steels possessing major improvements compared to 300 Series stainless steels, and a highly economical alternative to various nickel alloys.

    As with conventional austenitic stainless steels, the N’GENIUS Series has excellent ductility and toughness at sub-zero and cryogenic temperatures. But exceptionally higher strength and vastly superior corrosion resistance make this new family an entirely different proposition.

    Its unique combination of design characteristics provides key engineering advantages for the onshore and offshore industries.

    LNG piping systems, engineered products, fabricated products, and equipment can be developed and manufactured with reduced wall thicknesses, offering the potential to make products and equipment lighter and smaller, significantly reducing topside weight and helping facilities overcome space and height restrictions. Any space savings would also improve accessibility regarding servicing and maintenance, repairs, upgrading, or replacement work on products and equipment in the future.

    In particular, large facilities with extremely heavy topsides including floating production storage offloading (FPSO) vessels, FLNGs, and upstream fixed platforms, would greatly benefit from the design and construction advantages that the N’GENIUS Series can provide. This includes the potential to reduce the overall construction time and costs, as well as benefitting from easier handling and lower associated transportation costs.

    Dr. C.V. Roscoe, the inventor of the N’GENIUS Series, said:

    “Some of these larger facilities can have topsides weighing more than 50,000 metric tonnes, which has a major impact on the design and construction cost of oil, gas, and LNG projects.

    “The N’GENIUS Series has an infinite range of Alloy types, variants, and grades and is perfectly suited for all the different material specifications, scopes of work, and products including piping systems, pumps, valves, modules, vessels, and tanks. Therefore, the potential to optimize the weight and space of all these components, and in turn reduce costs, could be invaluable. It really is the total system material.”

    The weight-saving benefits provided by the N’GENIUS Series are achieved from superior wrought mechanical strength properties. For example, the minimum yield and tensile strength of the N’GENIUS 304LM4N and N’GENIUS 316LM4N grades are typically 2.5 and 1.5 times higher respectively compared to the minimum strength values of conventional 304L and 316L. This enables the N’GENIUS Series to have significantly higher allowable design stresses than conventional austenitic stainless steels.

    Similarly, the higher minimum Pitting Resistance Equivalent (PRE) values for N’GENIUS 304LM4N and N’GENIUS 316LM4N grades compared to those for 304L and 316L produce significant improvements in the localized corrosion and general corrosion resistance. This enables products and equipment to last longer, facilities to be designed for longer service life, and projects made more sustainable and cost-effective.

    Furthermore, the extensive range of alloy types, variants, and grades that form the ‘family’ of grades in the N’GENIUS Series makes it suitable for all products, in all service conditions, and in the harshest process media environments.

    The N’GENIUS Series will also help accelerate the wider implementation of carbon capture and storage (CCS) technology.  Inevitably, the addition of onboard CCS for upstream fixed platforms, FLNGs, and FPSOs means additional topside weight, volume, and space. So a reduction in the weight and size of onboard CCS systems, as could be achieved with N’GENIUS, would make this green technology become more feasible and play a fundamental role in driving down carbon emissions.

    The N’GENIUS Series can be manufactured in both wrought and cast forms, in an extensive range of products for the oil, gas, and LNG industries. These include pipe, tube, fittings, flanges for piping systems, modules, heat exchangers, umbilicals, and line pipe for risers, flowlines, pipelines, and manifolds. N’GENIUS technology can also be applied to engineering products including pumps and valves, fabricated products such as vessels and tanks, and specialist products including casing and tubing for Oil Country Tubular Goods (OCTG).

    A N’GENIUS technology with total system capability, truly living up to its name.

    The N’GENIUS Series is available to be produced under license by premier manufacturers of stainless steel products.
