The Novel feature of oil skimmer is to remove oil from the liquid. Oil skimmer plays a major role during the accided of oil tanker in sea port during the transportation in sea ports which create major disastor to marine ecosystem. The performance of oil skimmer enhanced by fire tuning the angle between the plane of disk and vertical plane the efficiency which improve the performance better than conventional disk oil skimmer. Thus the measure implemented will require less effort to alter from disk and belt skimmer, result shows requirement of less immersed area needed for offset angle to be perfect. About rotational speed of 80rpm will be effective, needless of operating or design parameter. Belt and disk skimmer shows the improved concentration of hydrocarbon in comparison with the existing oil skimmer.
