Hull Structural Monitoring System
INA-Hull
Real loads. Structural integrity. Lifecycle insight.
INA-Hull is Inalia’s modular hull structural monitoring system — instrumenting critical cross-sections of the ship hull to measure real bending moments, deformations, and structural responses under actual operating conditions. Designed to deliver continuous structural insight throughout the vessel’s operational life, INA-Hull provides the real load data that classification societies, operators, and O&M teams need to make informed structural and maintenance decisions.
Outputs & deliverables
Real-time deformation & bending moments
Sagging and hogging bending moments measured at critical hull cross-sections — delivered in real time through a customisable dashboard with configurable detail levels.
Global bending moment maps
Colour-coded visualisation of bending moment distribution along the hull — providing an immediate overview of structural loading across all monitored sections.
Structural utilisation & safety alerts
Real-time utilisation levels against structural design limits — with configurable alerts triggered when thresholds are approached or exceeded.
Load correlation with operational conditions
Hull loads correlated against sea state, heading, speed, and loading conditions — building a comprehensive understanding of how operational decisions affect structural performance.
Fatigue histograms & fatigue assessment
Load cycle counting, fatigue histograms, and hull fatigue assessment — supported by FEM models to deliver remaining useful life estimation at critical structural locations.
API integration & vessel management systems
Real-time data transmission to vessel management systems, SCADA, or classification society reporting platforms
How it works
-> Understand — We review section plans, load books, and structural documentation to identify critical measurement locations and define the monitoring strategy.
-> Strategy — Sensor placement optimisation across critical hull cross-sections, guided by structural analysis and bending moment distribution.
-> Install — On-board sensor installation, system commissioning, calibration, and functional validation.
-> Acquire — Continuous real-time data acquisition throughout vessel operation.
-> Analyse — Structural data interpreted within FEM model frameworks — delivering load distribution, fatigue assessment, and remaining useful life estimation.
-> Deliver — Real-time dashboard, structural alerts, fatigue reports, and API integration into vessel management systems.
Why INA-Hull
-> Engineering first — sensor placement and measurement strategy guided by structural analysis, not sensor availability.
-> Modular & vessel-adaptable — scalable from a single monitored section to full hull coverage, adaptable to any vessel type and configuration.
-> Classification society ready — data outputs and reporting designed to support class submission and structural integrity documentation.
-> Continuous lifecycle monitoring — real structural insight from first voyage to end of service life.
-> Single accountable partner — from system design and installation to data interpretation and structural reporting.
