Question 1 of 31048

Q

The maximum angle at which the intact stability curves are valid for MODU's is the angle for __________.

🔍 Key Concepts

• Intact stability curves (GZ curves) and what angle range they are typically considered valid for on Mobile Offshore Drilling Units (MODUs) • The meaning of limit of positive stability, downflooding angle, and small-angle stability • Regulatory guidance for MODU stability in 46 CFR and IMO MODU Code (general concepts, not exact text)

💭 Think About

• Ask yourself: up to what heel angle can you still rely on the calculated intact stability curve before another limiting condition makes it invalid? • Consider which of the listed angles represents a practical limit where the stability assumptions or watertight integrity may change significantly. • Think about whether intact stability curves are meant only for very small angles, or for a broader range up to a critical event like water entry or loss of positive righting arm.

✅ Before You Answer

• Be clear on the definition of downflooding angle and why it is critical for intact stability. • Review what is meant by limit of positive stability (where GZ becomes zero again) and whether curves can still be valid that far out. • Confirm whether small-angle stability usually refers to just the initial slope of the GZ curve or the full range of applicability of the intact stability curve.
