The operator of an Australian brownfield had been trying to develop the Exmouth basin as a stand-alone project. However, based on the highly complex field architecture, the project was becoming economically unviable, despite oil prices being significantly higher. The optimal solution involved integrated and standardized subsea equipment and was refined over time to remove subsea transformers and to include capital-efficient equipment.
