OFFSHORE PLATFORM DISPLACEMENT WITH AN INERTIAL REFERENCE SYSTEM
Platform displacement measurements are useful in evaluating analytical techniques, basic assumptions, and conditions related to platform dynamics. Light portable equipment using an inertial reference to measure platform motion is described. Amplitudes in the range of a few thousandths of an inch to a foot or more over a frequency band of one twentieth of a Hertz to several Hertz can be measured. Examples of calibration runs and actual platform tests are given. Methods of presenting data are illustrated including strip chart recording, horizontal plane platform motion plots, displacement spectrum plots and extended time multiple spectra plots.
