Pipeline Wall Thickness Assessment of Various Material Grades and Water Depths Using American and Norwegian Standards

Two standards that are widely used by many countries in designing offshore gas transmission pipelines American Standard – ASME B31.8, Gas Transmission and Distribution Piping Systems Norwegian DNVGL-ST-F101, Submarine Pipeline System. A thorough understanding of these is vital determining optimal pipeline design to ensure integrity for safe sustainable operations, as well striving economic efficiency. This study aims evaluate the wall thickness required designs using under different steel grades water depth conditions. costs then compared both at each condition commercial evaluation. Through this, standard can be determined. Mathcad software was data analysis accordance with mentioned all requirements including pressure containment, collapse, propagation buckling. Ultimately, Standards able provide a total cost 2.5% lower than project combination shallow, medium, deepwater depths along its route. However, medium shallow further reduce 2% only Standard. highlights importance considering several instead strictly adhering single better technical benefit.
