An Innovative Design and Construction Method of New-Build Hull-Platform for Floating, Production, Storage and Offloading

The demand for new-build FPSO hulls is increasing in order to reduce operational and maintenance cost and to install larger topside modules compared with tanker conversion FPSOs. However, low construction cost and fast-track construction are also required to the new-build FPSO as with the conversion FPSO, and they are challenging problems. In order to cope with those challenging problems, Mitsui E&S Shipbuilding Co., Ltd. were developed unique modular design and construction concept with simplified hull form, "noah-FPSO Hull" (noah : New Offshore Adapted Hull), and obtained Approval in Principle for the noah-FPSO Hull from two world leading classification societies, Bureau Veritas and American Bureau of Shipping. Its concept for unique modular design and multi-yard construction were introduced [1]. This paper presents specific modular design and adaptability for various oil fields.
