Hydrodynamic moments due to water on ship deck
Computer Assisted Methods in Engineering and Science, 2023 An analysis of the ship stability requires computer simulations of the ship motions leading to its capsizing. The large amplitudes of roll motion of the ship are connected with phenomena of immersing of ship deck into water.

Theoretical investigation on the seakeeping performance of a supply vessel with X-bow
Annals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2018 The X-bow concept was developed by Ulstein company, in order to increase the ship hydrodynamic performance. Low resistance, reduced fuel consumption, smoother motion and low acceleration levels are some of the hydrodynamics improvements.
