It has long been recognized that value creation for deepwater projects is predicated based on robust front end engineering and field development planning. Realizing this value requires a multidisciplinary approach that considers early engagement with the SURF execution team and the field development planning specialists, engineering specialists and project execution expertise. This paper presents an overview of recent experience and an illustration of the benefits of this approach. The general principles of field development optimization are presented, with an emphasis on Floater and SURF packages as well as the cost drivers to optimize the interfaces between these packages. This paper plans to explore the benefits of front end engineering design as it relates to early engagement of the SURF and Floater disciplines. The paper will examine through case studies topics such as: subsea production network alternatives, floater and riser conceptual and early phase design, and interfaces between the floater, riser and production system.

In the current offshore industry context, ways for significant cost optimizations must be explored and developed to make offshore projects viable. The cost share of the SURF (Subsea Umbilicals Risers and Flowlines) system is increasing, with developments in deeper waters and with more spread reservoirs. The SURF system also presents a wide range of possible options to be considered, thus with many opportunities for overall cost reductions.This paper presents examples of solutions to reduce costs: early engagement of SURF contractor for the field concept selection, global understanding and optimization of the field architecture, closely linked to installation vessels and methods selection, introduction of new technology, and consideration of interfaces between SURF, SPS (Subsea Production System) and Floater packages to reach a global optimum. The efficient development of these emerging solutions is supported by strong experience in full Engineering, Procurement, Construction and Installation (EPCI) execution of SURF contracts.• Possibility to integrate new technologies developed by SURF contractor into the field development plan, unlocking technical challenges or generating significant cost savings. • Robust cost estimates, execution schedule and risk evaluation, based on extensive EPCI project execution track-record.
