All-electric FPSO: onshore and offshore commissioning experience

Abstract

The increasing scope of electrical equipment in an offshore facility without turbo-driven End-Users has a known impact on the design of such facilities that has been discussed in the recent years [1]. The intent of this paper is to recall the historical events and present the specificities of such project execution from Vendor delivery (equipment FAT) until start-up of the facility (first oil and ramp-up). As such project is executed in many locations changing throughout time, from Vendor to yard, then towing to offshore, we will review splitting and sequencing of testing activities at the various locations and phases of project execution. A selection of the different issues encountered and solutions implemented eventually, will be covered with highlights on the priorities leading to the decisions which were taken. Feedbacks and lessons learned from designing, commissioning, operation and maintenance team perspective will be discussed in order to propose future roadmaps’ items for the industry.
