Welcome to our educational video on ship stability. In this tutorial, we explore how to determine the Free Surface Moment and VCG (Vertical Center of Gravity) using a Tank Sounding Table. It involves interpolation using a calculator.
"Free Surface Moment" refers to the effect of liquids moving freely within a partially filled compartment or tank on a ship. When a ship heels or lists, liquids within partially filled compartments or tanks will shift, creating a moment that can affect the vessel's stability.
Vertical center of gravity (VCG) is a critical parameter in ship stability analysis, representing the point within a ship where the vertical forces of gravity can be considered to act.
