ADVANCES IN NONLINEAR ANALYSIS METHODS FOR OCEAN STRUCTURES USING PARALLEL COMPUTERS

The design of complex ocean engineering systems such as advanced ship structures and offshore platforms requires continually increased levels of detail in supporting analysis. Such design activities require large speed and information management. Recent advances in parallel "super" computer technology provide the opportunity to upgrade current structural analysis capabilities. Most existing major structural analysis software systems were designed ten to twenty years ago and have been optimised for current sequential computers. Such systems often are not well structured to take maximum advantage of the recent and continuing revolution in parallel vector computing capabilities. These parallel vector architectures are now being made for personal computers (PCs) and engineering workstations. The paper discusses some recent advances in solving nonlinear structural dynamic problems relevant to ocean engineering applications. In particular the paper reports on the development and implementation of parallel processing software for finite element solutions to ocean engineering problems. It was shown that a parallel processing approach can significantly reduce execution time for large scale finite element problems typical of ocean engineering applications.
