N2 - Scouring process around subsea pipelines could reduce the soil bearing capacity which affected to the pipe stability. Scouring initial process against time should be known to discover scouring propagation. This paper aims to analyze the time scale calculation of 32 inch diameter in-Trench pipe, until meet the maximum-scouring-depth stage. Embedment (e/D) variation is given to know the impact to the scour propagation. Wave and current condition presented to meet the real condition. Wave orbital particle velocity (Uw) is calculated to obtain the non-dimensional factors (Uc/(Uc+Uw)) and KC. The results showed according to the deeper pipe embedment, it takes longer time to reach the maximum scouring depth.
