Offshore utility systems for FPSOs: A techno-environomic assessment considering the uncertainty about the natural gas price

Daniel Alexander Florez Orrego

Due to restricted weight and space budget on floating production, storage and offloading units (FPSO), the offshore utility systems have been limited to low-efficiency energy technologies. Moreover, owing to time-varying energy demands of the FPSOs, the ex ...
