Investigation of slamming loads during seaplane water landing under regular wave conditions
The Physics of FluidsThe safety of seaplane operations during water landings is critically influenced by wave-induced slamming loads, particularly in emergency scenarios. This study employs a validated numerical model incorporating heave and pitch motions to investigate the ...

Development of Simplified Structural Design Formulation for Slamming Loads
Volume 2: Structures, Safety and Reliability, 2008Impact Loads due to wave slamming on horizontal members of the hull structure are of considerable interest in the context of very light and optimized structure, as found on Naval Vessel and other high speed vessels. These Slamming Loads are highly dynamic in nature, which is characterized by very short duration of the load, usually 10–20 milli-seconds,

An Assessment of Load and Response for Horizontal Slamming Loads From Model Scale Experiments
Volume 3: Structures, Safety, and Reliability, 2018Steep breaking waves can result in high impact loads on offshore structures, and several model test campaigns have been conducted to assess the effect of horizontal wave slamming. High loads have been measured, and they can be challenging to withstand without significant deformation.

Prediction of Slamming Loads on Catamaran Wetdeck Using CFD
SNAME 13th International Conference on Fast Sea Transportation, 2015Wetdeck slamming is one of the principal hydrodynamic loads acting on catamarans. CFD techniques are shown to successfully characterise wetdeck slamming loads, as validated through a series of controlled-speed drop tests on a three-dimensional catamaran hullform model.

Inverse Estimation of Local Slamming Loads on a Jacket Structure
Journal of Offshore Mechanics and Arctic Engineering, 2017Slamming loads from plunging breaking waves feature a high impulsive force and a very short duration. It is difficult to measure these loads directly in experiments due to the dynamics of the structures. In this study, inverse approaches are investigated to estimate the local slamming loads on a jacket structure using hammer test and wave test data ...

The Analysis of Ship Structures Subjected to Slamming Loads
Journal of Ship Research, 1960This paper describes the results of a fundamental study of various phases of the ship structural design problem, as affected by slamming-type loads. By a slamming load, we mean a suddenly applied impact-type load such as is introduced for example, by: (a) The pitching and heaving motions induced by waves, which in turn cause the ship's bow to emerge ...

Development of empirical formulations of slamming loads for displacement vessels
Ocean Engineering, 2018Abstract The paper presents an empirical method to calculate slamming load acting as bottom impact pressure on the forward region of the vessel. Firstly, hull shape coefficient as a function of the deadrise angle of the section is derived. Relative velocity is derived in terms of the extreme motions, viz.

Analysis of wave load combination including slamming
1985It is necessary to estimate extreme sea loads when probabilistic and reliability methods are used to analyse t~e ultimate strength of ship corresponding to the modes of failure due to yielding or inelastic buckling. The ship response records taken in full-scale tests show that the vertical stress time his tory consists of a rapidly varying time history

Slamming Loads on a Wedge Elastically Suspended on a Marine Structure
Volume 11: Prof. Robert F. Beck Honoring Symposium on Marine Hydrodynamics, 2015Slamming loads on a two-dimensional wedge elastically suspended on a marine structure are analyzed by using either a combined Wagner and von Karman method (W-vK) or a boundary element method (BEM). Fully nonlinear free surface conditions are satisfied in the BEM. Hydroelasticity effects are considered in both methods.

Efficient Methods for Direct Calculation of Slamming Loads on Ships
Day 3 Fri, October 23, 2009, 2009This paper is concerned with slamming on ships, with particular emphasis on bow flare slamming. An efficient numerical method presented by Hermundstad and Moan (2007) is briefly described, and a summary of previous and new validation results is given.
