Engineering concerns of passing ship effect at typical waterfronts

Copyright 2018 by the International Society of Offshore and Polar Engineers (ISOPE) This article explores passing ship effect on vessels moored at typical waterfronts alongside a major waterway. Passing ship induced flow and its engagement with moored ships was traced with a Chimera, Reynolds-Averaged Navier-Stokes (RANS) based viscous flow solver. A parametric analysis was conducted to observe the passing ship effects induced by sole or dual new post-Panamax class ships in precise site condition of the waterway. Influences pertaining to the shape of the waterway and ship lane locations are quantified to guide facility design and pier operations. Findings confirm that certain large-scale seabed features, major channel dredging, as well as moored ship layout may noticeably raise the fluid forces on moored ships suffice to harm mooring structures and deter pier operations. Evidences are illustrated in excitation forces on moored ships. Practices to cope with passing ship adversities due to channel reconfiguration and growth in passing ship size are offered for operational consideration.
