Propeller-hull interaction effects in waves
Research Project, 2019 – 2021

In order to design fuel efficient ships and right install machinery onboard, ship designers need to know the interaction effects between a vessel’s components. For instance, neglecting the interaction effects between propeller, hull and rudder may result in under/over-prediction of the required power, about 10%. Thanks to the development of modern computational methods and to some extent the measurement techniques during the recent years, naval architects have been able to explore the interaction effects more in detail and enhance their designs. However, a large proportion of these studies have been carried out in model scale as well as in calm water where no incoming waves are involved. The objective of the current project is to push the boundaries of the ship hydrodynamics research field further forward and study the propeller-hull interaction effects in waves to introduce new possibilities for ship fuel consumption reduction.
