Requirement: One of the two FPSO
Because of changes in power consumption and the need for redundant power supply to FPSO (Floating Production Storage and Offloading Unit), it is strongly of interest to electrically interconnect units present in the same area using undersea cables. However, the impact on electrical plant in terms of dynamic stability, short circuit currents and harmonics must be analyzed in detail.
Capsim modelled all of the power grids using ETAP software so as to be able to calculate the power flows, the fault currents sizing the panels, harmonics and transients, in all the high demand configurations (offloading, pump start-ups, etc.). Specific electromagnetic transient studies, using PSIM, analyzed the problem of switching currents and resonances.
The study has allowed the customer to eliminate the technical uncertainties linked to the project and to design solutions to relieve the problems encountered.
