Abstract
En undervanns-rørlednlng (13) for transport av gass eller olje under høye temperaturer og trykk vil kunne utsettes for kompresjonsbelastninger som medfører bukllng og svikt av rørledningen. Dette kan man unngå ved å gl rørledningen (13) vekslende bøyer over lengden, da dette vil muliggjøre en sideveis bevegelse av rørledningen med tilhørende avlastning av l hvert fall noe av de l lengderetningen virkende kompresjons- krefter. En bøyet rørledning tilveiebringes ved at det tilveiebringes en rørledning (13) med utgangspunkt l rette rørseksjoner, hvoretter denne rørledning gis vekslende, dvs. i motsatt retning rettede bøyer. Rørledningen legges så i sjøen. Bøyene kan tilveie- bringes ved hjelp av par av kraftanordninger (15a,15b, 16a,16b,17a,17b) anordnet langs lengden av rørledningen (13) og beregnet til å påvirke diametralt motliggende sider av rørledningen (13).An underwater pipeline (13) for transporting gas or oil under high temperatures and pressures could be subjected to compressional loads which cause the piping and failure of the pipeline. This can be avoided by sliding the tubing (13) alternating bends over the length, as this will allow a lateral movement of the pipeline with associated relief of at least some of the compression forces acting in the longitudinal direction. A bent pipeline is provided by providing a pipeline (13) with the starting point in straight pipe sections, after which this pipeline is provided alternately, that is, in the opposite direction. The pipeline is then laid in the sea. The buoys can be provided by pairs of power devices (15a, 15b, 16a, 16b, 17a, 17b) arranged along the length of the pipeline (13) and intended to influence diametrically opposed sides of the pipeline (13).
