Grain Heeling - Volumetric Heeling Moment
Volumetric grain-heeling moment for a partly-filled bulk-carrier hold per International Grain Code §3 - the 25° heel criterion and residual-area check.
Heeling moment (t·m)
3,896t·m
λ₀
0.071m
Assumed heel angle
8.1deg
Status
Compliant (≤ 12° Grain Code limit)
Formula, assumptions, and limits
Grain Code limit: heel from shifted grain ≤ 12°, residual area between heeling arm and GZ ≥ 0.075 m·rad to 40° / flooding / max-GZ angle. Slack-hold tolerances strict.
