Cargo load movement in cylindrical tanks is incorporated into the static roll model (SRM) implemented in Microsoft Excel. A "generalized ellipse" equation allows a variety of cylindrical tank profiles to be analyzed. For a partially filled tank, the locus of the cargo center of gravity (CG) locations is determined as a function of the cargo surface slope. The cargo is then modeled as a single point mass that moves along a curved guide shaped as the obtained CG locus in the vertical plane. The cargo CG location is determined iteratively in a Virtual Basic routine that surrounds the current Microsoft Excel based solution technique thereby creating a transparent solution approach for the user.
