Holtrop and Mennen's method is arguably the most popular method to estimate resistance and powering of displacement type ships. It is based on the regression analysis of a vast range of model tests and trial data which give it a wide applicability. The Holtrop method computes a dimensional total resistance which is broken down into several components: frictional resistance, appendage resistance, wave resistance, resistance due to bulbous bow near the water surface, pressure resistance due to immersed transom, model‐ship correlation resistance, and air resistance. This chapter explains the resistance estimate for the container ship, and describes an estimate for the powering requirements. The powering estimate starts with the computation of thrust deduction fraction and relative rotative efficiency. The chapter shows the results for wake fraction estimates and the self propulsion point analysis based on the propeller characteristics.
