Damage and Failure in an X65 Steel Pipeline Caused by Trawl Gear Impact
Kristoffersen, Martin; Børvik, Tore; Langseth, Magnus; Hopperstad, Odd Sture; Ilstad, Håvar; Levold, Erik (Chapter, 2013)Offshore pipelines subjected to accidental impact loads from trawl gear or anchors may experience large global deformations and large local strains, creating a complex stress and strain history. In this study experiments ... -
Post Behaviour of Anchors Hooked by Pipelines
Dahle, Lars Johan (Master thesis, 2021)De siste tiårene har utviklingen av undersjøiske installasjoner økt i sammenheng med reduksjon i kostnaden for etablering av dem. I samme tidsrom, og for fremtiden, vil det være en økning av seilaser i Nordsjøen grunnet ... -
Simulation of Anchor Loads on Pipelines
Pettersen, Torunn Omnes (Master thesis, 2017)Anchor loads on pipelines are in general a rarely occurring event, but the severity when it happens could easily jeopardize the integrity of any pipeline. The environmental and economic consequences of an accident caused ... -
Transverse Deformation of Pressurised Pipes With Different Axial Loads
Kristoffersen, Martin; Børvik, Tore; Langseth, Magnus; Ilstad, Håvar; Levold, Erik (Chapter; Peer reviewed, 2017)Pipelines residing on the seabed are exposed to various hazards, one of them being denting, hooking and release of the pipeline by e.g. anchors or trawl gear. As a pipeline is displaced transversely in a hooking event, an ...
