Α large impulse is shown towards the development of a digital representation of the hull that will serve the purpose of constructing a structural digital twin that will eventually accompany the vessel throughout its lifetime. This work showcases the challenges encountered during the development process of a high fidelity finite element model of a particular vessel, that is the case of a 16.5 m aluminum passenger ship. The aim of the simulation is to reveal the detailed stress distribution, evaluate the results and define the acceptance criteria with respect to the allowable stress limits for the static structural analysis, as derived in accordance with the DNV guidelines (DNV 2021).
