Analysis on Deepwater Mooring System of Sandglass-Type FDPSO

doi:10.1007/s12204-015-1578-y

Abstract

Abstract: In order to solve the performance limitations of traditional ship-type and cylindrical FDPSO (floating drilling production, storage and offloading unit), we present a new FDPSO with a sandglass-type floating body. Based on the hydrodynamic performance of the newly developed floating model, a suitable analysis method for its deepwater mooring system has been proposed. Furthermore, by studying the effects of different mooring parameters on the motion performance of FDPSO, we achieve some useful conclusions and principles to design the mooring scheme in deep sea which has been validated to satisfy the Det Norshke Veritas (DNV) requirements. The study of this paper is expected to provide a reasonable and feasible reference and design solution for the deep sea positions of the new sandglass-type FDPSO.
