abstract:
Water on deck of ships is divided into two main scenarios. One is caused by
plunging breakers hitting the deck house or equipments directly. The other one
resembles the breaking of a dam and is focused on in this paper. Bow deck
wetness of a moored ship with blunt bow in regular head sea waves is studied
numerically by assuming the flow is two-dimensional in the centerplane of the
ship. It is shown that nonlinearities of the incident waves and due to wave-body
interaction are important. Stem overhang has a limited but positive effect in
relevant design conditions. Dam breaking models and shallow water
approximations for the flow on the deck have limited practical use. Impact
pressure distribution is studied in details. It is demonstrated that three-
dimensional flow effects must be accounted for in future studies.
