🔍 Key Concepts

• Roll period and how it relates to vessel stability and comfort/safety • Typical roll periods for large offshore vessels vs very small boats • Why operators prefer a longer roll period (slower, gentler motion) when going on location in moderate water depths

💭 Think About

• Compare each choice to what you would expect for a large drilling unit: would it realistically roll back and forth in less than 1 second? More than 15 seconds? • Think about which range of roll periods is usually considered dangerously short (snappy, uncomfortable) versus more comfortable and stable for heavy offshore units. • Ask yourself: if the roll angle is already small (2.5°), what sort of roll period would match a slow, gentle motion rather than a quick, jerky one?

✅ Before You Answer

• Eliminate any options that are clearly unrealistic for the size and inertia of a drilling unit like COASTAL DRILLER. • Focus on which choice best represents a slow, comfortable roll rather than a quick, sharp motion. • Before deciding, compare the numerical spread: very short (<2 s), moderate (~5–10 s), and very long (>15 s) roll periods, and match them to a large unit in 200 feet of water.
