Numerical Study on the Prediction of the Bow Flare Slamming Pressure for the Container Ship in Regular Wave

Abstract

A container ship has large flare on the bow flare region to accommodate more container recently. This flare region experiences the impact pressure due to slamming phenomenon under rough sea conditions. The impact pressure is transferred to the hull structure and the impact pressure causes structural damage. A strength assessment of the bow region is evaluated based on the empirical formulas according to various classifications. In this study, the numerical simulations were performed to compare with empirical method, and predict the bow flare slamming pressure on the container ship. It is found that the bow flare slamming pressure generated up to 625kPa near 0.975 station and the bow flare slamming pressure obtained from the formulas of the CSR and ABS tend to be similar to the CFD results.

Numerical simulation of the slamming effect of regular waves and freak waves on ultra heavy-lift amphibious connector

“…Moctar et al (2017) [1] presented a calculation method for evaluating the slam-induced whip response on ship cross-sectional loads in regular and irregular waves. Seo et al (2018) [2] used the CFD method to estimate the impact load of the bow of the container ship and gave the corresponding calculation formula according to different classifications. The results show that the impact load calculated by the general structural rules and ABS formula is basically consistent with the CFD calculation results.…”
