The Environmental-Driven Route Selection Paradigm
Shifting the Dominance of Distance Efficiency in Subsea Pipeline Installation in Indonesia

Environmental Constraints, Coastal Sensitivity, Route Avoidance, Subsea Pipelines, IndonesiaAbstract
Route selection for subsea pipelines in Indonesia has traditionally been dominated by distance efficiency parameters in order to minimize capital expenditures. However, this approach tends to overlook the complexity of Indonesia’s dynamic and sensitive marine ecosystems. This perspective article argues that Environmental and Coastal Sensitivity must be repositioned as a primary engineering constraint, rather than merely a regulatory barrier or a post-design obligation. Drawing on the theoretical foundations of coastal hydrodynamics and infrastructure risk management, the author critically analyzes the shortcomings of the “shortest route” approach, which often triggers technical risks such as premature corrosion, scouring, and free-spanning phenomena in coral reef and estuarine areas. The author proposes a Route Avoidance strategy as a superior engineering solution compared to conventional environmental compensation strategies. The analysis results show that integrating environmental sensitivity weights into a multi-criteria decisionmaking model not only protects biodiversity but also enhances the pipeline structure’s resilience to coastal morphological changes in Indonesian waters. This article concludes that a paradigm shift toward the “ecologically most stable route” is imperative to ensure long-term operational integrity and operational expense (OPEX) efficiency.
