... in the dynamic portion of an umbilical system. Super-duplex steel is the most common. and a well-proven material to use in dynamic steel tube umbilicals. A new type coiled tubing has entered the market: zinc-eoated carbon steel. The material has already been used in a number of static umbilical projects...

... the floater movements. Up to now dynamic umbilicals have been equivalent to umbilical designs comprising thermoplastic hoses as hydraulic lines. With the above in mind we starfed the development of the dynamic metal tube umbilical. The metallic tube umbilical has already proved itself in several static...

... 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...
