OFFSHORE CRANE OPERATIONS. PROGRESS REPORT NO. 2. DYNAMIC ANALYSIS OF OFFSHORE CRANES

This is a theoretical study of the dynamic properties of offshore cranes. The study was carried out by means of a finite element program with the possibility of direct integration in the time domain of the dynamic response. The study shows that the dynamic amplification in different members of the crane can vary significantly, and that the amplifications are fairly complex functions of the input parameters. It is concluded that the use of single mass-spring system for dynamic analyses calls for greater care and higher safety margins than when more accurate methods are employed. For the boom, the single mass-spring system should not be used.
