The International Towing Tank Conference (ITTC) 1978 performance prediction method is a procedure to predict the necessary delivered power of a vessel for trial conditions. It is part of the extensive set of model testing procedures recommended by the ITTC. The power prediction is based on the results of resistance test, open water test, and propulsion test. This chapter discusses the prediction of delivered power based on model tests. It determines delivered power for trial conditions based on model tests. The results of three different model tests contribute to the prediction of the full scale vessel performance in the ITTC 1978 performance prediction method. A fundamental flaw of the power prediction based on resistance, open water, and propulsion test is the decomposition of the hull‐propeller system into individual parts. Based on the delivered power, the required engine brake power is derived depending on shafting and gearing efficiency as well as suitable engine and sea margins.
