An experimental study of wave impact pressure on an FPSO bow under head sea conditions

Slamming Characteristics Due to the Special Shape of New Sandglass-Type Model in Waves by Comparing with Cylindrical Model

“…This is because the flare structure at the bow of the ship results in significant wave slamming. Park et al [17] studied the slamming pressure on the bow of the traditional ship-type FPSO model under various sea conditions; the timing of peak occurrence, peak value, and spatial distribution are discussed. Moreover, due to the large length-to-width ratio of ship-type FPSOs, their slamming exhibits strong directionality, significantly influenced by the direction of the waves.…”

Effect of bow hull form on the buckling strength assessment of the corner bracket connection

“…The bow region is subject to transient dynamic effects related to the slamming phenomenon that have been extensively studied and researched over the years; Acharya and Datta (2022) developed a parametric study to check the dependence of slamming pressure on physical and geometrical parameters and obtained an empirical formula for bow slamming. Park et al (2022) studied the characteristics of wave impact pressure on a bow, in 10, 50, 100, and 1000-year return period wave conditions by means of twelve force sensors installed on the bow. Jiao et al (2021) presented a method by integrating CFD and FEA to predict ship slamming taking into account hydroelastic effects in a simple bow flare and bottom slamming pressure estimations.…”

“…Ueda et al (1976) conducted a series of buckling analysis, elastic-plastic large deflection analysis and elastic-plastic thermal stress analysis for the triangular corner brackets subjected to compression to clarify the effects of initial imperfection (welding residual stresses and initial deflection) due to welding. Paetzold et al (2001) used the hot spot concept for different bracket details and studied the initiation and subsequent crack growth. Lee et al (2015) examined, through a nonlinear finite element analysis, the ultimate-strength characteristics of steel brackets to develop a simple design formula to predict the ultimate strength of a steel bracket.…”
