Description
Summary:A method is suggested for estimating the propulsion performance of a multi-shaft vessel. Possibility of applying one total thrust deduction coefficient to all ship shafts is justified and associated issues are discussed. Multi-shaft vessels are generically defined as vessels equipped with different types of propulsive units with non-similar geometry particulars or non-similar operating conditions, if geometry is the same. The paper suggests an iteration algorithm to estimate propulsion ship performance from standard data inputs obtained in model tests. An example of such calculations is given.
