Abstract. Submarine pipelines have been widely used to distribute oil and gas due to their high efficiency. However, the flow around the pipelines can cause structural failure to the submarine pipelines. This research aims to analyze the numerical modeling of characteristic seabed current around the submarine pipeline due to seabed current variation in transition depth using actual scale and Flow3D program. The result of this research shows that seabed current is dependent on pipe diameter (D), fluid depth (d), and wave height (H). The research shows that the bigger the pipe diameter and wave height, the velocity of seabed current will increase, meanwhile the deeper the fluid depth, the velocity of seabed current will decrease.
