.... Time histories of total platform force (net mooring force) and platform position are presented. Ice coverage, floe sizes and thickness are varied in the simulation set. The work represents a further exploration of the possibilities of GEM technology, which was previously used to explore both resistance...

... of load application. In advance and parallel, numerical simulations have been performed and their results will be given and compared with the measurements. In this paper the obtained test results are presented and conclusions are drawn with respect to the next tests and numerical simulations. marine...

... techniques is that only structures with an initial crack can be modeled. Other drawbacks of these techniques are geometry dependence and validity limits. In contrast, CZM can simulate fractures in any structures, with or without a crack. CZM is not confined to a class of materials, but can be used...

... Numerical simulations are carried out to examine the interaction of a managed ice cover with a drillship. Station keeping is maintained using a mooring system and Thruster-Assisted Mooring. The ice model is based on solving the momentum and constitutive equations, which determine the stresses...

... Numerical simulations are carried out to represent the historical data of ice interaction with the Kulluk during the 1980s. Three dimensional simulations include dynamics of the ice cover and the response of the mooring system. The results give modes of ice accumulation, clearing and ice forces...

... The paper explores the use of an event-mechanics approach to assess vessel performance in pack ice. The methodology is developed using massively parallel programming strategies on a GPU enabled workstation. A set of simulation domains, each containing hundreds of discrete and interacting ice...

... consequences. Preliminary numerical simulations of ice floe impacts on ice-class LNGC hull structures have shown this type of shock response as a result of flat-on-flat collisions. This paper aims to investigate the nature of flat-on-flat ice collisions and subsequent structural response through controlled...

... for each of the seven PC classes were examined: grillages with "built T" framing and grillages with "flatbar" framing. In short, the following simulations directly employ real-time/real-space measured full-scale ice loads, and thus provide insight into the structural capabilities of the various IACS URI...

... This paper presents the predictions of ice loads on a moored hull, based on model experiments and numerical simulations. Three levels of mooring stiffness were considered, which varied from an almost infinitely stiff system (used for ship resistance) to a mooring stiffness typical of those used...

... The combination of active learning classroom review of Arctic marine environment and ice navigation principles with realistic ship simulator exercises provides for reliable retention of nautical knowledge and skills. The Alaska Maritime Training Center in Seward, Alaska (AVTEC), has developed...
