Question 1 of 27070

While going on location in 250 feet water depth when the pitch angle of the COASTAL DRILLER is 2 degrees, the single amplitude pitch period should be longer than __________.

🔍 Key Concepts

• Natural period of pitch and how it relates to vessel size and water depth • Typical time scale for pitch motions on a large drilling vessel in seconds • Relationship between degrees of pitch angle and how quickly a vessel can realistically complete one pitch cycle

💭 Think About

• Estimate whether a large drilling vessel in 250 feet of water can realistically complete a full bow‑up to bow‑down motion in fractions of a second or if it usually takes several seconds per cycle. • Compare the orders of magnitude: are ship motions usually closer to fractions of a second (0.x s) or several seconds (x–tens of seconds)? • Think about your own experience at sea: when a vessel pitches, does it feel like a very rapid vibration or a slower, noticeable rise and fall?

✅ Before You Answer

• Eliminate any pitch periods that are unrealistically short for a vessel the size of the COASTAL DRILLER. • Consider whether the 2° pitch angle suggests gentle, longer-period motion or very fast, jerky motion. • Check which options fall into a realistic range for ship motions (typically a few seconds to a few tens of seconds, not tiny fractions of a second).
