Stability Test Theory - DMS Marine Consultant
It instantly calculates the vessel hydrostatics and reports the resulting weight, longitudinal center of buoyancy (LCB), and transverse center of buoyancy (TCB) to match that waterline. When the vessel sits in equilibrium, the LCG must equal the LCB and the TCG must equal the TCB.

6 Basics That Will Make the Ship Stability Easy to Understand
2017年6月24日 · This is known as the Vertical center of gravity (VCG) or simply KG. If the heavier weights are loaded on the top part of the ship, then COG of the ship will be towards the top of the vessel. In this case, KG of the ship will be a larger value.

2025年2月23日 · LCG is the Longitudinal Center of Gravity location, normally obtained from a "Weights and Moments" analysis. LCB is the Longitudinal Center of Buoyancy location, usually obtained from a "Curves of Form" plot.
2016年4月5日 · Displacement, LCG and VCG can be determined by a detailed shipyard weight estimate, with a confirming deadweight survey, to check the accuracy of the weight estimate. If the measured displacement and LCG agree with the predictions of the detailed weight estimate, then the estimated lightship VCG will be accepted as valid.

2009年3月2日 · LCG=longitudinal center of gravity 重心纵向位置 VCG=vertical center of gravity 重心垂向位置
since p= Distance (LCB ~ LCG), the location of LCG can be determined. Note that the value of p is the actual distance between B and G in the longitudinal direction.
The longitudinal, transverse, and vertical distances of the center of gravity from the various reference datums are abbreviated as LCG, TCG, and VCG (or KG for Keel to CG. Change in Displacement per Foot (or Inch) of Trim (CDTrim, CD1”, or CD1’)-As a vessel trims due to weight changes, the displacement changes as well as the trim.

2021年12月9日 · VCG(Vertical Center of Gravity)：垂向重心(高度)。 稳性(复原)力臂：船舶重心G至倾斜后浮力作用线的垂直距离，以GZ表示。 船舶排水量，以Δ表示。所以，船舶受外力矩作用发生倾斜后，产生的复原力矩Ms=Δ*GZ。
