All rights reserved.A three-dimensional non-orthogonal boundary fitted ocean circulation and sediment transport model (MuSed3D) was employed to conduct a risk assessment of Perusahaan Gas Negara (PGN) pipeline due to dredging activities in Banten Province, West Java, Indonesia. The pipeline starts from Bekasi Jakarta and ends in Maringgai Lampung, Indonesia. Dredging activities will change ocean circulation in the adjacent area, which can cause erosion or deposition along the pipeline. As a result, the erosion along the pipeline can increase the risk of pipeline failure. The model was run using wind, tidal forcing, and river discharge data to obtain water velocity and sedimentation processes along the pipeline. Wave hindcasting and transformation were also conducted to obtain wave height and period along the pipeline in nearshore region. The simulation results indicate that the dredging activities will increase the risk of pipeline failure at certain location on the pipeline.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Dredging,Erosion,Free span,Hydrodynamics,Marine pipeline,Model,Non-orthogonal curvilinear,Risk analysis,Sediment,Spherical coordinate[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors are grateful to the Perusahaan Gas Negara (PGN) for funding this study and to Dr. Semeidi Husrin of the Ministry of Marine Affairs and Fisheries Indonesia for providing the observation data.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.2112/SI91-001.1[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
