EMS for Interconnected O&G Offshore Facilities a Success Story

Abstract

As for any complex facilities electrically driven, and running islanded from a reliable Grid utility, Electrical availability is a key factor for processes’ profitability and safety.It is particularly true for an O&G Offshore structure of which Electrical power is ensured by Gas Turbine Generators fueled by local produced gas,Ensuring this availability with reliability, sustainability and coherence for two interconnected entities having capability to run independently or coupled, managed by 2 different Yards and accordant EPCs, involving more than 450 apparatus and devices from several manufacturers was a challenge that have been achieved.The intend of this paper is not to present technological insights linked to disruptive technologies’ implementation, but the methodology and lessons learned gained during the realization of a large scale and complex O&G project.Beyond implemented solutions, it reveals how and why, involvement, rigor, organization, pugnacity, consistency and confidence between teams from different organizations, often in competition, kept all along the project’s phases from FEED to Commissioning and Startup have governed the success.Ichthys EMS is the first milestone of a complete change of the EMS framework which adequately fits with the recent move of O&G’s Companies, from O&G Producers toward Energy Providers.
