Design Considerations for Deep Sea Mining Umbilicals

Outline: · De Regt Marine Cables. · The link between system requirements and umbilical requirements (which system requirements have the largest impact on the umbilical design). · Design options for deep sea mining umbilicals (showing the various options for strength member constructions, power conductors and data-transmission). · Technical challenges and risks (outline on the most important technical challenges and risks involved in the construction, production and usage of deep sea umbilicals). · Umbilicals for the SWORD and Blue Nodules project.
