POWERING CHARACTERISTICS OF A LOW-BLOCK DISPLACEMENT HULL FORM IN HEAD SEAS

Ship powering characteristics in a seaway were investigated for the model of a low-block coefficient, displacement-type hull in both regular and irregular head seas. The increase in power required to maintain speed was predicted by using both the regular-wave and the irregular-wave test results and these predictions were compared. Results indicate that when used within certain limits, the assumption held that added drag is proportional to wave height squared. (Author)
