During ship navigation on waves the relative motions i.a. occur which result in propeller emergence, and in consequence they cause the propeller thrust reduction. The article presents the algorithm for calculating the propeller thrust reduction as a result of the ship motions on waves having preset parameters: significant wave height , period and geographical direction.
