Abstract

Rørledning for transport av hydrokarboner i sjøen og innrettet til i det minste delvis å befinne seg på forholdsvis stor vanndybde, omfattende flere forskjellige lag (1,2,3) som tilsammen danner rørveggen i rørledningen, nemlig - et indre væske- og gasstett lag (3) av korrugert metall, - et utenforliggende styrkebærende lag (1) av et ikke-metallisk materiale og med en vesentlig grad av fleksibilitet, og - et mellomliggende trykkoverførende lag (2) av et materiale med vesentlig lavere elastisitetsmodul enn det korrugerte metall, anordnet mellom det indre lag (3) og det styrkebærende lag (1). Det er også beskrevet en fremgangsmåte for fremstilling av rørledningen.Pipeline for the transport of hydrocarbons in the sea and arranged to be at least partially at a relatively large water depth, comprising several different layers (1,2,3) which together form the pipe wall in the pipeline, namely - an internal liquid and gas-tight layer ( 3) of corrugated metal, - an outer strength-bearing layer (1) of a non-metallic material and with a considerable degree of flexibility, and - an intermediate pressure-transmitting layer (2) of a material with substantially lower elastic modulus than the corrugated metal, arranged between the inner layer (3) and the strength-bearing layer (1). There is also disclosed a method of making the pipeline.
