Q1 A three-level offshore platform located in the Helang Oilfield area has a 1500 kg floor
steel grating supported at each level. The structure sometimes is subjected to a vertical
ocillation movement during rough sea waves given by function of y(t) = Y sin ot
If the steel grating only moves in the vertical direction and is supported by one
equivalent spring and damper at each steel grating pole level with stiffness, k, = (300
xT) Nim, k= (200 x T) Nm and k = (100 × T) Ním while damping, c: = (15 x U)
Nsm, c: = (10 x U) Ns'm and c; = (5 x U) Nsim, respectively, as simplified in Figure
