The effect of design parameters on offshore piled platforms is discussed for structures in approximately 150 m of water. Variations in the following design criteria were investigated: marine growth, current, wave height, number and size of conductors, loading density and area, drag and inertial coefficients used in Morison's equation to calculate wave forces. Curves are presented that relate changes in the parameters to resultant weights. Two applications of the curves are presented: 1) predicting platform weights for future structures from known eights of existing platforms and 2) analyzing the effect on calculated weights for a future platform due to changes of 5 to 15 % of platform weights due to relatively small variations in environmental and configuration criteria.
