Global buckling av undervattensrörledningar med DEH kabel (Swedish)
Abstract [en]

Hydrates, wax, and other fluids forms in cold subsea pipelines which restrict flow of petroleum products during operation. This thesis analyses the global buckling behaviour of subsea pipelines with Direct Electric Heating cables (DEH) through a combination of analytical and FEM simulations. A subsea pipeline with an attached DEH cable has limited impact on the pipelines initial global buckling behaviour. The DEH cable holds back and reduces the buckle size. Strap distance and cable rotational location has very limited impact on buckling behaviour. Analytical and FEM model has in places low convergence, this is likely due to limitations in the models.

Abstract [sv]

Hydrater, vax, och andra fluider formas i kalla undervattensrörledningar som begränsar flödet av petroleumprodukter i drift. Detta examensarbete analyserar global buckling av undervattensrörledningar med Direct Electric Heating (DEH) kabel med en kombination av analytisk och FEM simuleringar. En undervattensrörledning med tillhörande DEH kabel har begränsad påverkan på en rörlednings initiala globala bucklingsbeteende. DEH kabeln håller tillbaka och reducerar bucklingsstorleken. Avstånd mellan remmar och kabelns läge har mycket begränsad påverkan på bucklingsbeteendet. Den analytiska och FEM‐modellen har i vissa fall låg konvergens, troligen på grund av begränsningar i modellerna.
