Mathematical models of varying complexity have been developed to predict forces occurring in a typical offshore platform crane while lifting from a supply boat. Computer programs based upon these models were used to assess the usefulness of these simulations. It is shown that a simple two-degrees-of-freedom model can be successfully employed at the feasibility design stage whereas a more sophisticated, multi-degree-of-freedom model is required for the detailed crane design. The programs were also used to investigate the influence upon the induced loads of various operational parameters including the load lifted, the jib angle, the line speed and the instantaneous deck velocity.
