Abstract
This paper describes a computer program capable of predicting the forces induced in an offshore platform cranes while offloading from supply vessels. The program, which is based upon the finite element method, is shown to be flexible, yet easy to use. Various computational techniques that save processor time and storage are described, along with a strategy to deal with system non-linearities. It is shown that by adoption of such techniques any reasonable two dimensional idealisation can be catered for on a mainframe computer of moderate size. The capabilities of the program are demonstrated by using it to investigate the optimum point of lift-off on the wave cycle and to predict the forces in a small scale physical model during a main hoist lift.
