<p style="text-align: justify">Over the years, with advancements in the shipping industry, there have been considerable increase in size, numbers and speed of ships. Ports and harbours have to handle these large ships and increased ship traffic within the limited space especially in the matured ports. Due to the above mentioned issues at the ports and harbours, passing ship interactions with moored ship is eventual. Pressure variations around the passing ship may causes additional forces and moment on the ship moored in the neighbourhood. Though there have been past literature on this subject, there is gap in few parameters which has been investigated. The passing ship forces on moored ship has been evaluated using Computational Fluid Dynamics (CFD), based on double-body flow model. Simulations were carried out for three-dimensional, unsteady, inviscid flow using overset meshing technique. The results obtained from CFD simulations were compared with the existing results obtained by experiments (Remery, 1974) for the validation of CFD model. Detailed parametric studies were carried out for parameters such as velocity ratio and displacement ratio, spacing ratio, and water depth ratio. Empirical equations for force and moment coefficients are derived based on the present study and recommendations for passing vessel distances from moored vessel has been made in the article.</p>

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
