Accelerated First Oil With Integrated Execution Model, Digital FEED Platform And Product Standardization

This paper illustrates how a subsea integrated ("SURF – Subsea Umbilicals Risers Flowlines" and "SPS – Subsea Production systems") execution model can be significantly improved in further reducing the time to first oil. It illustrates the use of digital platforms for FEEDs (Front End Engineering and Design) and Configure to Order (CTO) product designs to provide further schedule improvements resulting in an enhanced execution model. The time to first oil is considerably improved by cruising through the Front-End design gates using digital FEED platforms. CTO designs enable a project to reach the manufacturing gate faster by reducing detailed engineering effort significantly and in some cases eliminating it. The paper provides an introduction to the conventional execution model (Split SURF and SPS scopes), the integrated execution model (combined SURF and SPS scopes) and the enhanced integrated execution model (using digital FEED platform and CTO products). A comparison has been made on project delivery schedules between the three models illustrating the schedule savings through use of digital FEED platforms and CTO designs. It concludes that digitalization of FEEDs and standardization of product configurations create value for the operators in context of faster return on investment. Digital FEEDs are a new concept and still in its infancy. CTO design is a known concept; however, in context of a subsea project, how it may improve schedule delivery is not well established. These factors are truly an enhancement to the integrated execution approach and the additional value gets delivered to the end customer by further accelerating the time to first oil.
