Marine engineering
End-to-end structural analysis and monitoring engineering for offshore, naval, and high-performance marine platforms.
Services
-> Engineering-led monitoring strategy
Structural and hydrodynamic knowledge is the foundation of the monitoring strategy — defining what to measure, where, and why, and anticipating the sensitivity and accuracy achievable.
-> Turnkey installation in harsh environments
Offshore and subsea deployment experience — sensor installation, commissioning, calibration, and real-time data validation on site, where getting it right first time matters.
-> Data that closes the design loop
Field data interpreted within structural and hydrodynamic model frameworks (FEM, CFD, hydrodynamic) — delivering loads, fatigue, RUL — providing information that feeds back into design and O&M decisions.
"Once instrumentation is installed, adjustments are not straightforward. Missing structural information cannot be reconstructed afterwards."
This is why we invest heavily in the pre-measurement phase. A well-designed monitoring campaign with a short duration delivers more structural insight than a long campaign built on an unclear strategy. Our projects in the America's Cup, offshore wind, and wave energy have consistently validated this principle.
Tools & capabilities
Structural, Aerodynamic & Hydrodynamic Modelling
FEM, CFD, and OrcaFlex analysis services for the structural dimensioning, hydrodynamic characterisation, and fluidodynamic assessment of offshore and marine structures — providing the analytical foundation to validate design assumptions, define monitoring strategies or interpret field data
Monitoring Strategy design
Using structural and hydrodynamic models to analyse expected structural and hydrodynamic behaviour — then define the measurement strategy, sensor placement, acquisition architecture, and signal accuracy requirements. All before any hardware is procured.
Sensor commissioning and installation
Turnkey commissioning and instrumentation — strain gauges, fibre optics (FBG), accelerometers, pressure sensors, IMUs — selected and installed to meet the offshore environmental requirements of each project. Custom sensor development when commercial solutions fall short.
Data acquisition campaign
End-to-end management of monitoring campaigns — from system commissioning and real-time data validation to acquisition quality control and dataset delivery.
Data analysis & model correlation
Field data is interpreted within a structural model framework (FEM, CFD, OrcaFlex) to deliver real loads and stresses, performance, fatigue evolution, remaining useful life (RUL), and anomaly detection — correlated against design load cases and simulation models.
Digital Twins & SHM systems
Development of hybrid continuous structural health monitoring platforms combining direct sensor measurements with digital twin models — delivering early warning of anomalies, structural risk indicators, and data-driven maintenance recommendations to support informed O&M decisions throughout asset life.
