RANDOM DYNAMIC ANALYSIS OF MULTI-BODY ONSHORE STRUCTURES

A general method for the dynamic analysis of multi-body offshore structures is presented, being based on a constraint matrix approach. A method of deriving the constraint matrix for a general structure is given, and this is then used to derive the equations of motion of a whole system from those of its component parts. The response of the system to both first and second order random wave forces is found and then used to calculate the forces and moments in the connecting mechanisms. The structure is assumed to have rigid connecting parts and a linearised frequency domain analysis method is used, although other methods are discussed. The use of the method is illustrated by its application to both the single-buoy-storage <SBS> and Yoke-CALM <Catenary Anchor Leg Mooring> designs of offshore mooring terminal.
