To study the process of rapid sedimentation occurred required an understanding of the characteristics of the sediments and oceanographic processes. This paper is to analyse source of silting up and sediment distribution surrounding oil wharves of PT Caltex Pacifi  c Indonesia (PT CPI) after big dredging in 1990 during four months research and intensive survey in 18 research sampling areas. The research used gravimetric method for sediment samples identifi  cation and fi  eld survey for oceanographic conditions twice sampling time, fl  ood tide and ebb fl  ood. Data showed sediment fraction consist of sandy mud with 48.175–74.735% mud content. Classifi  cation and result of sediment statistic analysis indicated wave energy and tide caused silting-up process in the surrounding PT CPI’s oil wharves. This process was sped up by the environmental conditions, reclamation and coastal land changes.
