Hollenbach's method for resistance and powering estimates of single and twin screw vessels was developed in the 1990s based on test data of the Schiffbau Versuchsanstalt in Vienna, Austria. This method has a narrower range of applicability than Holtrop and Mennen's method, but seems to provide more reliable results, especially for twin screw vessels. In addition to the mean resistance at trial conditions, the method provides estimates for the minimum resistance (best case scenario) and for the maximum resistance (worst case scenario). Formulas for the resistance in ballast condition are presented as well. A complete propulsion estimate is possible based on estimates for the hull efficiency, thrust deduction fraction, and relative rotative efficiency, if open water propeller characteristics are known. This chapter presents the resistance and propulsion estimate for the 1000 TEU container ship.
