Equation 64 of Salvesen Tuck and Faltinsen (1970) is reproduced here as Equation ( 75 ) and gives the resultant shear force / bending moment of a hull in a seaway as:
|
|
where:
Vj is the resultant shear force or bending moment.
Ij is the inertial component.
Rj is the hydrostatic (restoring) component.
Ej is the wave excitation term.
Dj is the hydrodynamic component.
j is the degree of freedom 1 to 6.
The components are calculated by separate modules. For a
specified degree of freedom, each module return the complex coefficients of 
. So we may write 
as

( 76 ) |
The amplitude and phase of the resultant shear force or
bending moment is immediately available from the complex addition of the
coefficients of .
