Wave actions on side-by-side barges with sloshing effects: fixed–free arrangement

In offshore offloading operations, two vessels in a side-by-side configuration experience actions of both ambient water waves and liquid sloshing internal tanks. Under the excitation waves, complex multibody motions are induced, resulting tanks, concurrently can feedback to affect vessels’ motions. The interaction between barges coupled with effects is investigated for fixed–free arrangement. A numerical model developed based on boundary element method deal wave induced Due presence narrow gap vessels, resonance may occur, damping surface introduced suppress an unrealistic response near resonance. Concurrently, physical experiments without carried out. In-depth discussions motion characteristics given, Stokes non-Stokes natural frequencies associated discussed. significance present study twofold. Firstly, experimental measurements provide reference results validations simulations. Secondly, this work gives insight into under different headings which vessel operational safety.
