High-pressure gas pipelines often cross potentially unstable slopes under static and/or seismic conditions. Consequently, their structural integrity may be detrimentally affected by Permanent Ground Displacements (PGDs) due to landslides, leading to pipe failures. Since pipeline rerouting is often unfeasible due to various techno-economic restrictions, several mitigation measures have been developed to reduce the impact of landslides. Nonetheless, these mitigation measures are not always practical or cost-effective. To address this challenge, along with the overgrowing demands for safe and uninterrupted energy supply, the current study introduces a novel pipeline configuration, namely "S-shaped pipeline". This scheme refers to a pipeline with one or more sigmoid curvatures at specific locations within a potentially unstable slope. The optimal position of the prefabricated curved parts along the landslide zone has been examined via finite-element simulations. The results demonstrate the effectiveness of the proposed approach in handling detrimental local buckling phenomena in landslide-prone areas.
