Donut

Digital twin of mooring systems using ultrasound measurements

Donut is a multiple-phase Joint Industry Project (JIP) aiming at enabling remote assessment of mooring systems underwater. 

Reliable assessment of the integrity of mooring lines is of critical importance for the operation of floating energy production units, such as Floating Offshore Wind Turbines (FOWT) and Floating Production Storage and Offloading (FPSO). Damage in the mooring lines can create unacceptable risks to the entire asset and the subsea environment. The feasibility of detection, localization, and characterization of corrosion and fatigue damage in subsea chain links using active and passive techniques are investigated in this project, with the aim of creating/updating a digital twin of the mooring system.
