FIRSTLING-DIGIMAR, a Pilot Scale Digital Twin of a Marine Riser for Field Use

Abstract We developed and tested in real time FIRSTLING-DIGIMAR, a pilot scale digital twin of a marine riser driven by sparse field measurements. The FIRSTLING consists of hardware and software that includes a reduced order model developed through multi-fidelity methods combining massive field and experimental data, with low- and high-fidelity models, it is driven by real time measurements of a few sensors along the riser, and provides real-time fatigue life predictions with uncertainty quantification.
