Modeling of Accidental Oil Spills at Different Phases of LNG Terminal Construction

Accidental oil spills not only deteriorate biodiversity but also cause immediate threats to coastal environments. This study quantitatively investigates the initial dispersion of spilled using environmental fluid dynamics code (EFDC) model, loosely coupled with an endorsed spill model (MEDSLIK-II) accounting for time-dependent advection, diffusion, and physiochemical weathering surface slick. Focusing on local contributing factors (i.e., construction activities) dispersion, current is applied likely occurring at three different phases Songdo LNG terminal a reclaimed site in South Korea. Applied pose detailed ship collision scenarios generated based proposed plan terminal. The effects permeable revetments, required reclamation, currents were investigated subsequent modeling. For each scenario, simulated results showed distinct patterns transformation Oil absorption into coast, which causes immense damage communities, found be highly dependent tidal currents, volume spilled, nearby activities.
