Sustainable Development of Decommisioned FPSO as a Floating Solar Plant – Case Study of the Effects of Tilt Angle on Energy Efficiency Zi Lin, Xiaolei Liu

Abstract

Between 1977 and 2017, more than thirty floating production assets were removed, partly due to the high operation & maintenance (O&M) cost. On the other hand, global installations of floating PV have been more than doubled since 2016. Compared with fixed PV systems, floating PV has certain advantages. For instance, seawater can contribute to the cost-effective cooling mechanism of the PV panel. This paper presented a new concept of conveying decommissioned FPSO as a platform for floating PV plant. The proposed PV system is designed to power offshore platforms or drilling rigs. Effects of tilt angle on energy outputs were evaluated through a frequency-domain hydrodynamic analysis of the FPSO. Results showed that roll motion has a larger negative effect on the total radiation on a collector, compared with pitch motion.
