Dense buried pipelines network, such as in implemented in parallel, can be installed in different process and storage mills, such as geological gas and hydrocarbon storages. Their corrosion resistance is ensured by a combination of organic coating and cathodic protection (CP). For maintenance operation on a specific pipeline, the CP can be turned off for safety reasons. Thus, the operated pipeline can be affected by CP influence from other surrounding protected ones. This phenomenon is supported in the field by different pigging inspections, highlighting local corrosion induced by output stray current on coating defects. In the literature, many studies focused on CP influences by finite and/or boundary element modeling. However, usually the foreign structures considered (under influence) are limited to bare steel or fully coated pipeline. Moreover, most of these studies are not confronted with experimental works. To our knowledge, the actual influence between the different pipelines is not much documented in the literature and not quantified. In this study, an experiment consisting in 3.00 x 1.80 x 0.80 m sand tank, equipped with 4 full scale parallel pipelines, with 17 model defects were realized. The model defects reproduce uniformly degraded coating and local defects. The experimental work allows i) measuring the DC influence under different CP configurations, and ii) providing stray current data for finite element modelling (FEM). The FEM was performed in a two steps i) a CP distribution in terms of current demand and electric field on protected pipelines, and ii) application of this electric field to the foreign pipeline. The good agreement obtained allows a validation the proposed approach and globally assess the riskier scenario in terms of nature of the defect, applied CP and soil environment.

The non-metallic glass fiber reinforced GFRP bars has gained worldwide acceptance recently and are now being used in several applications in reinforced concrete structures such as sea wall, bridges, foundation, marine structure, pavements, barriers, and piles (1–3). The major impetus for its usage in Saudi Arabia emerged from the strategic decision by Saudi Aramco to make it mandatory for several non-structural applications such as slab-on-grade, stormwater channels, bulkheads, and pipe supports. The motivation was to combat the high cost of repair, rehabilitation, and reconstruction of deteriorated steel-reinforced concrete structures in a short span of time (4).
