.... This is believed to be the industry's first ever topside retermination of an in service, steel tube umbilical. The success of this offshore operation is significant to Shell and the greater operations community due to anticipated maintenance of aging, steel tube umbilicals like the Europa umbilical. Shell has...

... and separation technology, enhanced recovery through water and gas injection, subsea sampling, enhanced vertical deepwater trees (EVDT), steel lazy wave catenary risers, and high voltage multiplexed electro-hydraulic steel tube umbilicals. During its nine year development since sanctioning, the professionals...

... such as tensile armors and steel tubes. The basis for fatigue damage assessment of such elements is the long-term stress cycle distribution at critical locations on the helix elements caused by long-term environmental loading on the system. Establishment of the long-term stress cycle distribution requires global...

... Abstract The amount of crush load that steel tube umbilicals can sustain frominstallation tensioners can significantly influence the cost of deployment, particularly in deepwater developments. As installation vessel selection has to be made, in most cases, well beforephysical testing...

... Abstract Steel Tube Umbilicals (STUs) are integral to many offshore production systems and must be designed to endure demanding fatigue environments over the course of their service life. It is therefore fundamental that the design methods employed to calculate the fatigue life of STUs...

... in modeling for fatigue prediction. However, in deeper waters and larger umbilicals, such interactions can contribute to umbilical failure. Steel tube umbilicals (STUs) link a host/control platform to associated wells and provide the hydraulic, electrical, signal and chemical functionality required for each...

... Abstract A critical component in the wet tree development of deep water fields is the umbilical riser. Failure of the umbilical can result in partial or total loss of production, with resulting severe economic consequences. In many recent deep water projects, steel tubes for control...

... Abstract This paper discusses the design and the installation of steel tube umbilicals for service in 3000 metres water depth. Designs of functional components and umbilical cross sections to cope with the specific requirements of the ultra deep water are reviewed in terms of availability...

... innovations and standardization across the entire portfolio of projects laying the foundation for continuous technical and cost improvement. Several advances in umbilical technology and cost improvements have resulted from this focused effort including the use of large, steel tube umbilicals, the introduction...

... wells. A steel tube umbilical design utilizing relatively large diameter, carbon steel tubing was selected for this project. Design verification testing was conducted and the umbilical was successfully manufactured and installed. The viability of utilizing continuous carbon steel tubing for subsea...

... Abstract Floating production systems need freely suspended umbilicals, i.e. dynamic umbilicals to remotely control the offset subsea oil wells. Steel tubes have a number of operational advantages that the traditional thermoplastic hoses do not. These advantages are also desirable to have...

... offshore applications. This paper describes the main steps in the working method and development towards metallic umbilicals for dynamic applications. Following our introduction of this new generation of umbilicals to the market, a steel tube umbilical for dynamic application, installed on a TLP are now...

... ABSTRACT This paper describes a new concept for steel tube umbilical, with an integrated optional methanol or service line. The theoretical basis of the umbilical concept is established, based on existing experience form flowline bundle developments. The umbilical characteristics...
