Article Type: Research Papers
J. Offshore Mech. Arct. Eng. October 2020, 142(5): 051601.
Paper No: OMAE-19-1208
Published Online: March 30, 2020
...Hamed Azimi; Hodjat Shiri Prediction of subgouge soil deformation during an ice gouging event is a challenging design factor in Arctic subsea pipelines. An accurate assessment of ice keel–seabed interaction requires expensive model testing and large deformation finite element analysis. Proposing...

...Ahmed Reda; Gareth L. Forbes; Ibrahim A. Sultan; Ian M. Howard Flow of gas in pipelines is subject to thermodynamic conditions which produces two-phase bulks (i.e., slugs) within the axial pipeline flow. These moving slugs apply a moving load on the free spanning pipe sections, which consequently...

... of the major methods available for estimating the drag forces on pipelines and piles caused by a mass gravity soil movement has been presented and compared with one another. The methods available are limited in terms of the application and provide a wide range of estimates. There is significant room...

...Arash Nobahar; Shawn Kenny; Tony King; Richard McKenna; Ryan Phillips In cold environments, marine pipelines may be at risk from ice keels that gouge the seabed. Large quantities of material are displaced and soil deformations beneath a gouge may be substantial. To meet safety criteria, excessive...
