Drag Moment Component, Mjy{d, S) 



The drag moment component about the bottom due to wave pressures acting on a 

 vertical member extending up to an elevation, S, is presented as Equation (27) and 

 presented (Table VII) in dimensionless form as: 



M^ = 



CDPD(H/T)^h' 



Inertia Moment Component, Mj{d, S) 



The inertia moment component about the bottom due to wave pressures acting on a 

 vertical member extending up to an elevation S, is defined in Equation, (28) and presented 

 (Table VIII) in dimensionless form as: 



M ' = 



C^PTTDMH/T^h^ 



Dynamic Pressure Component, Pr^i^, S) 



The dynamic pressure component, defined by Equation, (29) is tabulated (Table IX) in 

 dimensionless form as: 



Pn' = k75- 



^1 Pd 



This completes the description of the field variables (depending on d and S) that are 

 included in the tables.
