    Of interest in this project are the states of stress and deformation in pipelines buried in soil scoured by moving ice ridges. Specifically, acomputational tool customized for the analysis of the complete ridge-soil-pipeline system will be developed and applied to a parametric study of pipeline deformation due to seabed scour by ice ridges. long (Hotzel & Miller ). Ice scour affects lakes as well. The floor of Lake Erie has ice scours up to m wide, 2 m deep and 6 km long in water depths of as much as 25 m (Grass ). The seabed may preserve ice scour marks for many years. Blasco et al. () estimated the age of a 50 km long scour . A general framework is described for the solution of two-phase fluid-object interaction problems on the basis of coupling a distributed-Lagrange-multiplier fictitious domain method and a level-set method, intended for application to the problem of seabed scour by ice ridges. ice scour.

Noun. ice scour (plural ice scours) a narrow ditch on a seabed caused by the movement of pack ice;.

Krissek, L. A., Late Cenozoic ice rafting records from ODP Leg sites in the North Pacific: Late Miocene onset, late Pliocene intensification and Plio-Pleistocene events. Proc. Ocean Drilling Prog. Sci. Results, (), – The first, major part of the book is devoted to marine pipelines, describing in detail all kinds of scour scenarios, and also making recommendations for scour protection.

Other kinds of structures considered are single piles (slender or large), groups of piles, complex subsea structures, breakwaters, and by:   In addition, ocean-seabed-infrastructure interaction can cause sediment transport and scour, altering the seabed geometry and causing changes in embedment and support.

Ice scour and seabed engineering book This Geotechnique lecture tackles the geotechnical challenge of designing infrastructure for an evolving seabed, examining ‘whole-life’ changes in seabed strength and geometry.

In Konuk et al. (), an ice Ice scour and seabed engineering book problem is studied with two different soil media, one representing the seabed soils and the other representing the infill material in the pipeline trench. It is. The scour was less severe than that shown in Figure 5(a) as (a) the structure had a 235 m diameter flat-bottomed foundation (rather than a deep skirt) which had been placed about 35 m below seabed level, (b) the scour model simulated the placed filter material mobility rather than the natural seabed and (c) the water depth was greater.

An in-situ program was carried out in the Van Mijen fjord on Spitsbergen during the and winter seasons to investigate the ice ridge scour process. Two ice scour tests and one shear off. Scouring of the seabed by ice masses poses great threat to structural integrity and safety of buried structures such as oil and gas pipes.

Large ridge motions and large seabed deformations. Ibrahim Konuk, In recent years, several computational models were published for the analysis of pipelines subjected to ice scour.

With one exception, most of these models assumed uniform seabed soil properties. This paper studies the effects of different seabed soil stratigraphies on the ice scour : Ibrahim Konuk, Shenkai Yu.

Sediment is mobile at the seabed and is transported by marine currents. Mobile sediment creates features from small ripples to large sediment banks and waves that can migrate on average meters per year.

Oceanographic currents can scour the seabed and remove sediment especially where the shape of the seafloor is Size: 3MB. Get this from a library. Evaluation of sea bottom ice scour models.

Seabed scouring by ice is a large-scale disturbance to polar coasts. Grounding ice modifies seabed topography, reworks the sediment, and ploughs and crushes the seabed biota.

The effects of ice scour on soft-sediment benthos were examined in Barrow Strait in High Arctic by: The seabed disturbance in Arctic regions comes predominently through horizontal cutting mechanisms induced by natural processes such as iceberg scour.

Shrinking sea ice is significantly increasing the rate at which the icebergs scour the seabed and the study predicts that the Antarctic Peninsula is going to get hit more frequently. Seabed gouging by ice is a process that occurs when floating ice features (typically icebergs and sea ice ridges) drift into shallower areas and their keel comes into contact with the seabed.

As they keep drifting, they produce long, narrow furrows most often called gouges, or scours. This phenomenon is common in offshore environments where ice is known to exist.

Impact of environmental factors on the distribution of extreme scouring (gouging) events, Canadian Beaufort Shelf. Seabed repetitive mapping surveys between and and again from to have led to the identification of 17, new ice scour (gouge) events across the Cited by: 2.

A submarine pipeline (also known as marine, subsea or offshore pipeline) is a pipeline that is laid on the seabed or below it inside a trench. In some cases, the pipeline is mostly on-land but in places it crosses water expanses, such as small seas, straits and rivers.

Submarine pipelines are used primarily to carry oil or gas, but transportation of water is also important. “A review of recent iceberg scour survey data from the Labrador Shelf”.

This feature is less than a few tens of meters in size and typically occurs within 30 km from a river mouth, in the sea ice expanse that is fastened to the coastline (known as fast ice).
