Power Delivery and Umbilical Cable Optimisation for Long Offset Tiebacks

摘要

In this paper we present a study into the physical and practical limitations of different power transmission techniques for long offset tiebacks. The results from the study present a definitive operating envelope for varying offset tiebacks and subsea power demands. The study is supported by in-depth performance analyses covering a range of power transmission techniques and umbilical cable designs. We also include the economic considerations when evaluating the different power delivery and umbilical cable selections.
