IMO intact stability
Intact stability — GM, righting arm, wind heel
Ask Deckhand to check a floating platform's intact stability — metacentric height, righting-arm curve and wind heel — against the IMO criteria.
What you can ask it to do
- Compute metacentric height (GM) and the righting-arm (GZ) curve.
- Check wind-heel and area-ratio criteria against the IMO intact-stability rules.
- Report the governing criterion and the margin.

Questions
What governs intact stability?
The IMO Intact Stability (IS) Code criteria — minimum GM, righting-arm area ratios and a wind-heel check — adapted for offshore floaters and MODUs.
What does Deckhand return?
GM, the GZ curve, the wind-heel and area-ratio checks, and the governing criterion with its margin.
