摘要：In order to solve the limitations of the hydrodynamic performance of traditional ship-type and cylindrical FDPSO (floating, drilling, production, storage and offloading unit), this paper proposes a new concept of sandglass-type FDPSO. For the new floating model, by using classic boundary element method, the characteristic of its heave motion response can be studied. Then based on the wave potential theory, engineering estimation expressions of heave motion performance are theoretically and mathematically deduced to summarise the design guidelines and schemes for sandglass-type floating body. Furthermore, according to the information of a ship-type FDPSO named as MPF, a sandglass-type floating body of new FDPSO with the same basic function has been designed. Finally, compared with ship-type, cylindrical and semi-submersible floating body, the design guideline in this paper can be validated to be effective and rational. New sandglass-type design can significantly improve the hydrodynamic performance of FDPSO. Therefore this paper can provide an innovative engineering platform and design proposal for the development of deep-water oil and gas.
