Ship Loading Condition - Calculator
Enter each load item in the table below including weight, center of gravity and free surface (if any) together with the ships lightweight. The calculator
will calculate the displacement, the combined center of gravity and the VCG/GM correction because of the free surface effect.
The calculator accepts up to 30 line items, but less is also accepted. Please reach out to us using the contact form on the page if more lines are needed.
Abbreviations
- Weight - Weight of each item in ton
- LCG - Longitudinal Center of Gravity. Typically measured from the aft perpendicular (AP)
- TCG - Transverse Center of Gravity. Measured from the centerline. Typically positive to port and negative to starboard
- VCG - Vertical Center of Gravity also known as KG. Measured from the baseline which is typically at the top of the keel or keelplate.
- FSM - Free surface moment in t×m. Calculated as Free Surface in m4×specific gravity in kg/m3
- Lightweight - The empty weight of the ship
