Question 1 of 2066636ef128f7522a1c522661

The DEEP DRILLER in transit is level at 23.0 feet draft. Strong winds are blowing from the starboard. A careful load form calculation determines that the TCG is 2.0 feet to starboard. What is the value of the wind heeling moment?

🔍 Key Concepts

• Transverse Center of Gravity (TCG) and how it creates a heeling moment when off the centerline • Relationship between displacement (in long tons), TCG (in feet), and heeling moment (foot-long tons) • How wind from starboard affects a vessel whose TCG is shifted to starboard

💭 Think About

• How do you convert a TCG in feet and a vessel’s displacement in long tons into a heeling moment? Think about the basic moment formula. • If the TCG is 2.0 feet to starboard, in which direction does that cause the vessel to heel, and does wind from starboard increase or oppose that effect? • Which answer choices seem too small or too large when you think about a realistic displacement for a unit like DEEP DRILLER?

✅ Before You Answer

• Recall the formula: Moment = Weight × Distance, and make sure your units are long tons and feet. • Estimate or recall the vessel’s displacement used in this type of exam problem and multiply by the given TCG (2.0 feet). • Compare your computed moment with the available choices and eliminate those that are clearly off by a factor of 2, 5, or 10.
