Undersea pipeline route planning in coastal areas requires an approach that integrates engineering and environmental aspects simultaneously from the early stages of design. Based on a literature review of the "Guidelines for Marine and Coastal Environmental Impact Assessment" by the International Finance Corporation as well as scientific publications such as "GIS-Based Multi-Criteria Analysis for Pipeline Route Selection" by Springer and various studies in the journal Ocean Engineering (Elsevier), it is known that environmental constraint is an important parameter in engineering planning. The concept of coastal sensitivity which includes mangrove areas, estuaries, and coral reefs is integrated into the route selection process through a GIS-based approach and multi-criteria decision analysis. The results of the study show that route avoidance strategies for sensitive areas not only significantly reduce ecological impacts, but also improve technical efficiency by minimizing risks such as seabed soil instability, disturbances during installation, and potential additional costs due to advanced mitigation. In addition, international guidelines affirm that avoidance is a priority step before mitigation in the hierarchy of environmental impact management. Thus, route avoidance can be positioned as an integral part of the engineering strategy in undersea pipeline planning, not just a response to environmental regulations, but rather as a design approach that supports the sustainability and reliability of infrastructure in sensitive coastal areas.
