Integrated Front-End Work; Models, Benefits, and Challenges

The subsea industry has for many years operated with a field development model where the work is split between the Subsea Production System(SPS) suppliers and the Subsea Umbilical, Riser and Flowline (SURF) (includes also installation) suppliers. The last years it has been a very strong focus on integrated studies and execution projects in the industry, as many believes this will have major benefits in both executing the necessary studies and the execution projects. This paper describes the findings of benefits and challenges for early phase study work from several recent studies with some different integration models, and the different models will be discussed. The studies were done in a company that have been merged from a Subsea Production System company and a Subsea Umbilical, Riser and Flowline company. However, as these two disciplines does not cover a complete subsea field development, the impact of the interfaces not being covered by the SPS and SURF integration is also to some degree discussed. Furthermore, the transfer to, and impact on the execution project is touched on in the paper.

The paper concludes that integrated study models has several benefits, such as less time used to communicate between the parties, and that better concepts is likely as the interface issues can be solved and challenged over the table. However, there are challenges, such as the concepts may become proprietary, and the interfaces not covered by the integration model.
