Symbols

For symbols not defined in this section, refer to Ch 1, Sec 4.

λ : Wave length, in m.

Bx : Moulded breadth at the waterline, in m, at the considered cross section.

x, y, z : X, Y and Z coordinates, in m, of the load point with respect to the reference coordinate system defined in Ch 4, Sec 1, [1.2.1].

fxL : Ratio as defined in Ch 4, Sec 2.

fyB : Ratio between Y-coordinate of the load point and Bx, to be taken as:
  • , but not greater than 1.0.
  • fyB = 0 when Bx = 0.
fyB1 : Ratio between Y-coordinate of the load point and B, to be taken as:
  • , but not greater than 1.0

Cw : Wave coefficient defined in Ch 4, Sec 4.

fT : Ratio as defined in Ch 4, Sec 3.

PW,WL : Wave pressure at the waterline, kN/m2, for the considered dynamic load case.
  • PW. WL = PW for y = Bx/2 and z = TLC
hW : Water head equivalent to the pressure at waterline, in m, to be taken as:

fps : Coefficient for strength assessment, as defined in Ch 4, Sec 3.

θ : Roll angle, in deg, as defined in Ch 4, Sec 3, [2.1.1].

Tθ : Roll period, in s, as defined in Ch 4, Sec 3, [2.1.1].

ffa : Coefficient defined in Ch 4, Sec 3.

fβ : Coefficient defined in Ch 4, Sec 4.

zSD : Z coordinate, in m, of the midpoint of stiffener span, or of the middle of the elementary plate panel.
