2.5D geophysical model of the Gällivare mining area: An integrated study to model the top 4 km of the subsurface and guide for future exploration activities
(Peer reviewed; Journal article, 2021) -
2.5D Inversion and Joint Interpretation of CSEM Data at Sleipner CO2 Storage
(Peer reviewed; Journal article, 2017)In this paper, we revisit the marine controlled-source electromagnetic (CSEM) data, acquired above the Sleipner CO2 storage, in order to further study the dataset and conclude the feasibility of marine CSEM for offshore ... -

3D fault integrity screening for Smeaheia CO2 injection site
(Lecture, 2018)Task leader, Elin Skurtveit presents the GHGT paper "3D fault integrity screening for Smeaheia CO2 injection site" together with plans for future work. -
3D FE tool for time dependent settlement predictions
(Chapter, 2016)A newly developed calculation tool for fully coupled general 3D finite element consolidation analyses is presented. The development has been part of an ongoing Research and Development project called GeoFuture and the tool ... -
3D FE-Informed Laboratory Soil Testing for the Design of Offshore Wind Turbine Monopiles
(Peer reviewed; Journal article, 2021) -
3D stability analyses of Skjeggestad landslide
(Peer reviewed; Journal article, 2021)In 2015, a sudden landslide caused the failure of one of the pillars supporting the southern lanes of the Skjeggestad Bridge near Mofjellbekken on Expressway E18. The transportation corridor was closed to traffic for 17 ... -
A Benchmark Case Study for Seismic Event Relative Location
(Peer reviewed; Journal article, 2020)“Precision seismology” encompasses a set of methods which use differential measurements of time-delays to estimate the relative locations of earthquakes and explosions. Delay-times estimated from signal correlations often ... -
A Boussinesq type extension of the GeoClaw model - a study of wave breaking phenomena applying dispersive long wave models
(Peer reviewed; Journal article, 2017)The nonlinear shallow water model is widely used in the study of tsunami propagation, but an increasing number of studies are dedicated to the dispersion dynamics of tsunamis. If the wave dispersion becomes important, ... -
A climatic trigger for the giant Troll pockmark field in the northern North Sea
(Journal article; Peer reviewed, 2017)Pockmarks are seafloor craters usually formed during methane release on continental margins. However, the mechanisms behind their formation and dynamics remain elusive. Here we report detailed investigations on one of the ... -
A computational platform to assess liquefaction-induced loss at critical infrastructures scale
(Peer reviewed; Journal article, 2021) -
A Constitutive Model for Soft Clays Incorporating Elastic and Plastic Cross-Anisotropy
(Peer reviewed; Journal article, 2017)Natural clays exhibit a significant degree of anisotropy in their fabric, which initially is derived from the shape of the clay platelets, deposition process and one-dimensional consolidation. Various authors have proposed ... -
A field laboratory for monitoring CO2 leakage
(Journal article, 2009)The long-term safety of future CO2 storage projects in aquifers will not only rely on a comprehensive geological characterisation of the formation and capillary seal, but also on the ability to effectively monitor the ... -
A Framework for Versatile Shape of Yield Surfaces for Structured Aniso-tropic Soft Soils
(Chapter, 2016)A framework based on logarithmic contractancy is proposed to produce versatile shapes of yield surfaces for structured anisotropic clays. The recently proposed constitutive model (E-SCLAY1S) is an extension of existing ... -
A geochemical, mineralogical and geotechnical characterization of the low plastic, highly sensitive glaciomarine clay at Dragvoll, Norway
(Peer reviewed; Journal article, 2019)The sediments at the NTNU research site Dragvoll, Trondheim, Norway accumulated in seawater close to the glacier front during the Pleistocene-Holocene transition. A comprehensive site investigation and laboratory test ... -
A GIS method for assessment of rock slide tsunami hazard in Norwegian lakes and reservoirs
(Journal article, 2009)An evaluation of rock slide tsunami hazard is applied to all Norwegian lakes larger than 0.1 km2 based on their topographical setting. The analysis results in a topographic rock slide potential score that indicates the ... -
A macro-element for integrated time domain analyses representing bucket foundations for offshore wind turbines
(Peer reviewed; Journal article, 2018)The paper presents a macro-element model for bucket foundations to be used in integrated time domain analyses of offshore wind turbines. The macro-element has been formulated in the multi-surface plasticity framework, and ... -
A macro-element model for multidirectional cyclic lateral loading of monopiles in clay
(Journal article; Peer reviewed, 2018)This paper investigates numerically the impact of multidirectional cyclic loads on the response of a monopile in clay supporting an offshore wind turbine (OWT). The results indicate that multidirectional loading modifies ...
