Don - A Cost-Effective Approach to Subsea Design

Marginal developments in the U.K. sector of the North Sea require an approach that reduces project development costs and risks while providing safe and reliable operation. This paper illustrates how the Don petroleum development satisfied these criteria, although the project was characterized by significant uncertainties. At the time of project approval, Don was the deepest and farthest subsea development from the host platform in the U.K. sector.
