Digital twin of the Calm Water Tank Facility at the Istitute of Marine Engineering of the Italian National Research Council

This report describes the realization of a comprehensive digital model of the Calm Water Towing (CWT) tank facility at the Institute of Marine Engineering (CNR-INM). The digital model describes the full infrastructure, including the tank and the towing carriage, and provides a digital twin that allows to simulate the various phases in preparation, execution and decommissioning of experimental activities in the facility. The digital twin has been developed in a Solid Works software environment and consists in a digital project, with drawings, previews, rendering and animations that can be downloaded in the most popular formats. In the report, the methodology has been described and examples of applications of the digital tool to ongoing and future activities are described. The activity has been undertaken and partially funded in the framework of the CNR Project ULYSSES 2030 (Underpinning Laboratory for Sea Energy Systems) and of the EU-funded project, H2020 CRIMSON, dealing with the demonstration of innovative hydrokinetic turbines for the exploitation of tidal and river energy. Nonetheless, the validity of the digital twin is general, with application to all types of testing programs in the facility.
