Engineering Smarter Cable Stability Solutions
Aurora Offshore Engineering (AOE) brings proven expertise in On-Bottom Stability (OBS) analysis for subsea cables used in offshore wind, interconnectors, tidal energy, and other projects.
From Complex Analysis to Clear Insight
Traditional On-Bottom Stability analysis methods (DNV-RP-F109) were designed for pipelines — not cables.
AOE has built on these standards to create a more accurate approach that reflects real-world cable behaviour, accounting for factors like wave action, seabed mobility, and shallow-water conditions.
Setting New Standards in Cable Stability
Through years of project experience, AOE has utilised STABLEpipe (for mobile seabeds) and COREstab (for rocky seabeds) — innovative methods now referenced in international standards including DNV-RP-F109:2021 and BS 10009.Meet AuroraCAT — Cable Analysis Made Simple
To make these advanced techniques accessible to industry professionals, AOE created AuroraCAT, the Aurora Cable Analysis Tool.
Analyse with Confidence
With just a few inputs — cable specifications, metocean data, and seabed type — users can quickly run:- Standard DNV-RP-F109 Absolute & Generalised stability analysis
- Enhanced AOE AbStab (includes wave breaking, high KC number and boundary layer effects)
- STABLEpipe for mobile seabeds
- COREstab for rocky seabeds
Early Insights for Better Design Decisions
AuroraCAT gives engineers and project teams the ability to perform reliable preliminary stability checks before detailed OBS analysis — helping to save time, reduce uncertainty, and improve design efficiency.Available at
