Effect of Hull and Propeller Roughness during the Assessment of Ship Fuel Consumption
نویسندگان
چکیده
The effects of hull and propeller roughness are presented over ten years operation on ship performance. developed model used in this study is a combination NavCad Matlab to perform the resistance propulsion computations selected as well processing input output data. By considering hull, engine installed an optimized propeller, performance computed for different according ITTC recommendations opinion experts marine field. Twelve cases simulated operations compared new has dominant effect due its large area. However, by adding roughness, increment noticed loading ratio fuel consumption 1–4% 2–4%, respectively, addition roughness. From study, it concluded that both important consider achieve more accurate results than just

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
