Umbilicals

Detailed knowledge and understanding of the structural design of umbilicals is the key to safe and efficient use. 

Kongsberg Oil & Gas Technologies is working with umbilicals from all the major manufacturers in Europe, Far-East, US and Brazil, gaining in-depth knowledge of the designs and their behaviour. Combined with advanced tailor-made finite element based computer programs, we provide high-end engineering services for all types of umbilical designs in static or dynamic applications.

Over the years we have established several umbilical qualification programs, including full-scale tests, umbilical component tests and advanced analysis, to provide the required level of confidence for safe and cost effective use of umbilicals in demanding applications:

• Dynamic analyses with regular or irregular sea
• Design and optimisation of umbilical configurations
• Cross section review and optimisation
• Umbilical fitness-for-purpose evaluations
• Definition and follow-up of qualification programmes
• Detailed stress analysis of steel wires, steel tubes and copper elements using state of the art FE tools
• Fatigue analysis of steel and copper elements
• Detailed FE-analysis of umbilical end-fittings and accessoires
• Inspection and dissection services
