🔍 Key Concepts

• Relationship between KGL, VM (virtual mass moment) and FSML (free surface moment of liquids)** • How to convert a total moment (in ft-tons) into a height in feet using the vessel’s displacement • Effect of free surface: how FSM changes the position of G (KGL)

💭 Think About

• First, think about what physical quantity VM represents and how you normally get GM or KG from a moment and a displacement. • Ask yourself: is FSML added to or subtracted from VM when finding the corrected position of G (KGL)? Why? • Consider whether you need the vessel’s displacement in tons to turn ft-tons into feet, and how that displacement is obtained from the given data.

✅ Before You Answer

• Be clear on whether VM already includes or excludes the effect of free surface. Do not double-count free surface. • Check that all terms in your final formula for KGL have compatible units (ft-tons vs feet). • Verify whether an assumed or previously given displacement for DEEP DRILLER is needed from an earlier part of the exam or stability table to complete the calculation.
