Turritella FPSO—Design and Fabrication of the World’s Deepest Producing Unit

The Stones Project is in the emerging Lower Tertiary trend in the Gulf of Mexico ultradeep water. A floating production, storage, and offloading (FPSO) unit was selected for the floating production system to address the stepwise development of the Stones Field. The Turritella FPSO (Fig. 1 above) is the deepest floating production system in the world and presented many challenges to successful execution of the surface host facilities.

Overview

The Stones development is along the Walker Ridge protraction area in the deepwater Gulf of Mexico, in water depths ranging from 7,500 to 9,500 ft.
