Question 1 of 27070

An inclined semisubmersible with a very short rolling period about a constant angle of list is likely to have __________.

🔍 Key Concepts

• GM (metacentric height) and its effect on rolling period • Relationship between constant angle of list and transverse center of gravity (TCG) • How free surface effect changes GM and roll behavior

💭 Think About

• Think about what a short rolling period tells you about the vessel’s stability and the size of GM. • If the vessel is inclined at a constant angle of list, what does that suggest about the horizontal location of the center of gravity compared to the center of buoyancy? • How would excessive free surfaces normally affect GM and the speed of roll — would it make the roll faster or slower?

✅ Before You Answer

• Relate short rolling period to whether GM is large or small. • Decide which options describe a condition that would increase GM versus those that would decrease it. • Check which options are consistent with a steady list (constant heel) rather than an unstable or slowly rolling condition.
