🔍 Key Concepts

• natural roll period of a vessel or MODU • effect of wave period matching the vessel’s roll period • how resonance affects roll amplitude vs roll period

💭 Think About

• Think about what happens to any object (like a swing) when the push frequency matches its natural period. Does the timing itself change, or does the motion’s size change? • Does matching the wave period to the vessel’s roll period make the roll slower/faster, or does it mainly affect how far the vessel rolls each side? • Which option best describes a special condition that can be dangerous because it can greatly increase rolling?

✅ Before You Answer

• Be clear on the difference between roll period (time to complete one roll cycle) and roll amplitude (how many degrees the vessel heels). • Ask yourself if matching periods tends to increase the period or simply increase the motion’s energy at that period. • Identify which choice describes a known dangerous rolling condition that naval architects and MODU stability guidance specifically warn about.
