Platform motion measuring system

摘要

A method and apparatus for measuring the motion of tall structures, particularly offshore platforms. The method comprises disposing a number of accelerometer packages in a tubular member attached to a vertical or near vertical member of the structure. Each package contains three accelerometers having their axes dipsosed in an orthogonal arrangement. The apparatus includes means for installing and removing a plurality of packages from tubular members or chutes that are permanently attached to the structure.
