Paper presented at the Arctic Technology Conference, October 24–26, 2016
Paper Number: OTC-27355-MS
... Abstract Flexural failure of sea ice is of interest in many different applications, ranging from understanding rubble formation processes to modeling bending failure of ice sheets against sloped structures and ship hulls. In this paper we present a brief summary of recent in-situ experiments...

Paper Number: OTC-27405-MS
... Abstract In preparation to the SALTO JIP (Safe Arctic Logistics, Transport & Operations) work was done towards developing an improved model for icing due to sea spray at the bow of a ship. The so-called SHIPICE model may be used in a probabilistic risk-based approach and consists of two...

... Abstract This paper describes the essence of establishing a dynamic fugacity model, mainly in the framework of assessing the potential risk posed by oil spills during Arctic shipping. Key to evaluating this risk is the fate and transport processes as they occur in ice-covered waters. A review...

Paper presented at the OTC Arctic Technology Conference, March 23–25, 2015
Paper Number: OTC-25519-MS
... Abstract Iceberg ice is complex to model as properties tend to vary with a wide range of parameters (temperature, strain rate, bubbles, etc.) resulting in complex failure envelopes with low tensile strengths. This is compounded by the presence of size effects where larger areas typically have...
