Structural health monitoring for hulls and FPSOs

Light Structures builds SENSFIB, a fibre optic structural health monitoring system that reads the stress a structure is carrying in real time. Sensors bonded to a hull, FPSO, or platform measure strain continuously, so structural fatigue is a live measurement rather than a periodic inspection finding.

Track record and clients

SENSFIB is installed on more than 400 vessels across 20 or more countries, including tankers, LNG carriers, naval ships, and offshore rigs. It holds ABS SMART SHM Tier 3 certification, the structural health monitoring standard recognised by the classification society. Light Structures also runs a Hybrid Digital Twin that combines the live stress data with a DNV Risk-Based Inspection framework, moving the data from monitoring into inspection planning and predictive maintenance.

Features and benefits

The sensors are bonded with adhesive, with no welding and no moving parts. No welding means no hot work to install, which matters on a live hydrocarbon asset, and no moving parts means the system does not need annual recalibration. So it can be considered for an asset already in service, not only a newbuild.

Why it is in the Hub

Pulse represents Light Structures in Australia because the question for a WA operator running an FPSO or managing an LNG carrier fleet is whether structural fatigue can be measured rather than estimated, and inspection planned against real loading rather than a calendar. SENSFIB answers both, and the no-hot-work installation makes it viable on assets already on station.
