Symbols
For symbols not defined in this section, refer to Ch 1, Sec 4.
x : X coordinate, in m, of the calculation point with respect to the reference coordinate system defined in Ch 4, Sec 1, [1.2.1].
Cw : Wave coefficient, to be taken as:
fβ : Heading correction factor, to be taken as:
- For strength assessment:
- fβ = 1.05 for HSM and FSM load cases for the extreme sea loads design load scenario.
- fβ = 0.8 for BSR and BSP load cases for the extreme sea loads design load scenario.
- fβ = 1.0 for HSA, OST and OSA load cases for the extreme sea loads design load scenario.
- fβ = 1.0 for ballast water exchange at sea, harbour/sheltered water and accidental flooded design load scenarios.
- For fatigue assessment:
- fβ = 1.0.
fps : Coefficient, as defined in Ch 4, Sec 3.
BSR, BSP, HSM, HSA, FSM, OST, OSA : Dynamic load cases, as defined in Ch 4, Sec 2.
