Seakeeping, Hydrodynamics

Paper

It is well known that the dynamic of the stepped hull in real scale is rather complex and it’s not easy to predict that using empirical or mathematical approaches, and by numerical and experimental way as well. Moreover, there is huge lack in literature of data related to sea trials of stepped hull. Furthermore, the reliability of full-scale CFD simulations is not widely proven and validated...

Propulsion, Ship Machinery

Paper

Luxury high speed boats are increasingly being used for entertainment purposes however, not only humans, but also animals are negatively affected by high speed boats, and time is running out fast for people to do something about it.
In this study, a review of current negative effects of high speed boats to the environment are presented. Then, two main source of negative effect of high speed...

40. Stern Flap Solution to Contain the Speed Performance Loss due to the Ship Weight Growth: an Application on the “De La Penne” Destroyer Class

Design

Paper

It is well known that during the life-cycle the growth of the ship weight is one of the main source of the performance-loss. Stern flaps have been used in many recent designs of transom stern vessels, in particular by the US Navy, to increase top speed or to realize improvements in fuel economy over the operating range. Furthermore, stern flap implementation has also become a practical...
