THE EFFECT OF VARIATIONS IN DESIGN CRITERIA ON STEEL OFFSHORE STRUCTURES

The effect of design parameters on the structural weight of offshore piled platforms is discussed for structures in about 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 weights of existing platforms and 2) analyzing the effect on calculated weights for a future platform due to changes in design criteria.
