... conventional approach than those commonly employed for offshore failure scenarios, use of bow-ties can support effective management of these risks, especially those requiring proactive management of safeguards, particularly ice feature overload, offshore collisions, multi-line mooring failures, and loss...

... takes place. The 10-year or 100-year environmental ice features should be established for MODU and permanent moorings respectively considering the following: Site-specific ice features such as level ice, ice ridge, ice floe, iceberg, etc. For each ice feature, define the limiting mechanism for ice...

..., and various storage and platform combinations are designed to passively resist the full spectrum of ice forces to which they are likely to be subjected. Active structures, which in some way actively destroy or avoid ice features capable of causing damage to References, nomenclature, and figures at end...

... ABSTRACT In offshore oil exploration, it is often necessary to protect sub-sea equipment from damage from anchors, fishing nets, ice features or other marine hazards. Equipment protruding from the sea floor in high traffic areas, such as shipping lanes or areas with submarine activity, has...

... scenarios of environmental parameters were defined, representative of the northern, central and southern regions of the Bering Sea. These three locations, indicated in Figure 1, were selected because the extent of ice cover and size of ice features varies considerably from the northern to southern...

... over the ice to create typical "limit-stress" loads on narrow structures. With the move towards platforms for the offshore arctic, structures became wider than had been previously built, and much thicker ice features became part of the ice interaction scenarios for design. Loads calculated using...

... Abstract Most ice mechanics research for arctic structures has been devoted to predictions of the maximum design ice force in global terms. It is now being recognized that the local pressure between the ice feature and the structure is also a very important design variable. Local design...

... loads on structures assume that sufficient driving force is available to sustain failure of the design ice feature against a structure. This paper assesses limits to the environmental driving force in a first-year ice field by considering analytical models of ridge formation, wind and current driving...

... below the depth reached by an ice sheet having the maximum natural thickness for the area. This configuration is designed to fail thick ice features in flexure. In the depth region of the natural ice sheet formation where adfreeze may occur, a cylindrical leg section is used to limit the area exposed...
