Designofhydro-elastic model tests of  a 5000 meters floating bridge in an ocean basin is not an easy task. The size of an ocean basin and the size of the bridge are only two of the many challenges that the engineers & researchers need to takecare of. The generation of environmental conditions is another challenge that could potentially impact the quality of the tests significantly.Installation of a gigantic model is demanding, considering the accuracy of the installation and strength of modelcomponents. Significant amount of preparation and design work should be carriedout beforehand ona case-specificbasis.The presentation shares some thoughts the presenter went through in the process of such a task.
