In this paper multibody dynamics techniques are reviewed for their applicability to offshore engineering, for example to cases like installation, decommissioning, salvage, offloading, pipe laying and dredging. The basis of every simulation is formed by the equations of motion. Multibody techniques have the advantage over analytical methods that they are generic: the equations of motions are derived by a computer algorithm rather than by hand. This allows for a large variety of systems to be analyzed with a single program. The review shows that the topology dependent semi-recursive velocity transformation method (VTM) provides a computationally efficient method for spatial time domain simulations. As an application a crane vessel payload-pendulation problem is studied. The initial results of this study suggest that multibody techniques in offshore dynamics provide better insight and possibly higher accuracy in response prediction than other methods.
