What Does Service The Staility Track Mean
The curve of statical stability, or GZ curve equally it is most normally referred to, is a graphical representation of the send'due south transverse statical stability.
Transverse statical stability is the term used to describe the ability of a transport to render to the upright, when it has been forcibly heeled past an external force and is momentarily at rest when floating in still h2o.
RIGHTING MOMENT (t-k) = GZ (m) 10 DISPLACEMENT (t)
At any angle of heel, it is the horizontal disposition of Chiliad and B that determines the GZ value.
Every bit a ship progressively heels over the righting lever, GZ, increases to some maximum value and so decreases until at some angle of heel it becomes negative i.e. it becomes a capsizing lever.
Computing the value of GZ, at specified angles of heel for a ship'south item condition of loading, volition allow a curve of statical stability, or GZ curve, to exist produced.
The greater the values of GZ, the greater will be the area under the curve.
BASIC Data Bachelor FROM THE CURVE OF STATICAL STABILITY
Consider the curve in the previous example. The following information tin can be extracted from information technology:
(a) The GZ value for any angle of heel.
This can be used to calculate the moment of statical stability for the ship at that detail bending of heel if the formula:
RIGHTING MOMENT (t-thousand) = GZ (1000) ten Displacement (t) is practical.
(b) The maximum GZ and the angle of heel at which information technology occurs.
(c) The range of positive stability and the angle of vanishing stability (AVS).
(d) The approximate angle of deck edge immersion (θDEI).
The ship heeled to the indicate where deck edge immersion takes place.
The angle at which this occurs is identified on the curve equally the point where the curve trend changes from increasing steepness to decreasing steepness. This is known every bit the point of inflexion of the curve.
