While interacting with a sloping structure, an ice floe may fracture in different patterns. For example, it can be local bending failure or global splitting failure depending on the contact properties, geometry and confinement ...

This paper presents a novel automatic real-time remote sensing algorithm that uses radar images and global positioning satellite system measurements to estimate the ice-drift velocity vector in a region around a free-floating ...

In the autumn of 2015, the Norwegian University of Science and Technology (NTNU) and the Swedish Polar Research Secretariat (SPRS) performed a research cruise named the “Oden Arctic Technology Research Cruise 2015” ...

This thesis is a collection of papers focusing on various aspects of dynamic positioning of marine vessels in ice. Most emphasis is put on the dynamic broken, or managed, sea-ice environment where pioneering operations ...

Studies of wave-ice interactions include field and laboratory experiments, theoretical model developments, the implementation of these theoretical models in simulation tools, and the validation and calibration of these ...

Floating glacial ice features of various sizes pose a substantial threat to the structural integrity of offshore structures in ice-prone regions. Relatively small ice feathers, e.g., bergy bits and growlers, are a major ...

The ice floe shape and size distribution are important ice parameters in ice-structure analyses. Before performing an analysis at full scale, the dynamic positioning (DP) experiments in model ice at the Hamburg Ship Model ...

Sea ice’s fracture properties are in general difficult to measure and there is still on-going debate on the proper way to conduct valid measurements. Among many controversy fracture test conditions, the size of the test ...
