A novel approach to expand the reach of classic structural health monitoring systems

Jérôme de LAUZON, Alexis BENHAMOU, Alexandru ANDONIU - Bureau Veritas Marine & Offshore - Paris La Défense (France)

 

Structural health monitoring of ships has become a recurring subject of research, almost “trendy”. On top of periodic inspections, which allow the detection of structural damage and the monitoring of corrosion, it could indeed prove useful to continuously monitor the structural response of the ship, for instance to make sure that it operates within the bounds determined during the design phase.

In the past few years, Bureau Veritas has been working on a novel method, based both on direct measurements and numerical computations, which aims at increasing the reach of classical structural health monitoring. On top of the monitoring of instrumented areas, it allows the monitoring of non-instrumented structural details. This paper aims at explaining this “hybrid” method by placing it in the context of other monitoring approaches, and presents two actual application cases on a navy vessel and an FPSO.
