Paper presented at the Offshore Site Investigation and Geotechnics: Integrated Technologies - Present and Future, September 12–14, 2012
Paper Number: SUT-OSIG-12-34
... to study the stability of piles in sands and clays subject to a large variety of cyclic loading histories. Centri- fuge testing has proved its efficiency in conducting extensive series of tests, as it allows a large range of parameters to be varied while keeping associated costs relatively low, when...

... of dredged material. From economic and ecologic points of view, this amount should be reduced to the only what is most necessary. Steep slopes are most efficient, but their stability must be proven and be guaranteed at least until construction work finished. Neglecting disturbances from waves (etc...

...1. Introduction Evaluation of deepwater geohazards commonly en- tails assessment of slope stability either to under- stand the geologic history of a project area, or to an- ticipate the risk associated with future events, such as major earthquakes. This can be done qualitatively based on the...

... Abstract Submarine landslides are one of the major hazards for offshore pipelines. Progressive differential ground movements caused by earthquakes can initiate run-out/debris flows that can impact and damage pipelines. Hence, both the stability of submarine slopes caused by earthquakes and the...

... hydrate stabil- ity. Once melted due to the circulation of hot fluid in the casing, hydrate bearing sediments will suffer degradation in their mechanical properties (e.g. strength and stiffness), accompanied by overpressure development5. Moreover the gas released by hydrate dissociation may undermine the...

... ABSTRACT The Ormen Lange gas field is located in about 900 to 1100 m water depth in the slide scar of the enormous Storegga Slide that occurred about 8000 years ago. The slide left steep and high headwalls above and below the planned field development area. Today's stability of the headwalls...
