Q

The longitudinal free surface correction of a floating MODU displacing 12,000 kips is 1.20 feet. What would be the new FSCL if 2,400 kips of solid variable loads are added?

🔍 Key Concepts

• Free surface correction (FSCL) and how it changes when displacement changes • Relationship between liquid free surface and solid loads • Proportionality of FSCL to the ratio of existing displacement to new displacement

💭 Think About

• When you add solid variable loads, what happens to displacement and to the relative effect of the existing free surface? • Is the free surface correction usually directly or inversely proportional to the vessel’s displacement? • How would you adjust the original 1.20 ft correction to account for an increase from 12,000 kips to 14,400 kips?

✅ Before You Answer

• Compute the new displacement after adding the solid loads • Apply the correct ratio between old and new displacement to scale the original FSCL • Check whether adding solid weight should make the free surface correction larger or smaller in magnitude
