STRUCTURAL DESIGN AND FABRICATION METHODS FOR A MULTI-HULL FLOATING PRODUCTION UNIT

A methodology is developed for the preliminary structural design of tandem hull floating production systems. These systems are actively being considered by operators as an alternative to more traditional vessels because of their low fabrication cost and reduced motions in waves. The structural design methodology differs from the conventional monohull hull girder approach for preliminary design in that it adopts an inter-linked double girder model. The model is presented in this paper and is utilised to provide the structural response of a tandem hull vessel responding in head seas. In addition, vessel fabrication methods are discussed and the importance of assessing the limit state behaviour of the inter-hull connectors and their influence on the overall hull design is briefly presented using results from the non-linear structural analysis methods.
