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

αp : Correction factor for the panel aspect ratio to be taken as follow but not to be taken greater than 1.0.

a : Length of plate panel, in mm, as defined in Ch 3, Sec 7, [2.2.2].

b : Breadth of plate panel, in mm, as defined in Ch 3, Sec 7, [2.2.2].

P : Design pressure for the considered design load set, see Ch 6, Sec 2, [2], calculated at the load calculation point defined in Ch 3, Sec 7, [2.2], in kN/m2.

σhg : Hull girder bending stress, in N/mm2, as defined in Ch 6, Sec 2, [1.1], calculated at the load calculation point as defined in Ch 3, Sec 7, [2.2].

χ : Coefficient taken equal to:
  • In intact condition:
