Resumo

Recently, digital twin has emerged as an alternative technology to predict the structural integrity of

ships and offshore structures with good accuracy in real time. An appropriate digital twin for this field of appli-
cation should consider important aspects such as the harsh environmental conditions and load variations that are

induced during the lifetime of the involved components. The behavior of mooring lines, risers and the floating
unit compose a complex coupled system, which has to be modeled by the digital twin. A large amount of data
can be collected by monitoring systems or inspections. This paper presents a methodology for developing a digital
twin ship for a FPSO (Floating Production Storage and Offloading) capable of being coupled with external data
and automatically run multiple numerical analyses. The proposed methodology employs a three-cargo tank length
model in three dimensions via FEM (Finite Element Method) to receive information, solve the structural analyses
and check the results for damage detection on hotspots of the model. This procedure can be applied in different
approaches to help on ship operation by checking generated results for several conditions that can be considered
with numerous variations of parameters and avoid excessive maintenance proceedings that may have a significant
impact on operations.
