Per Olav Moslet is a PhD student at NTNU and UNIS. The background for Moslet’s doctoral thesis is that there are uncertainties regarding the magnitude of ice loads on structures. The load calculations should to a larger extent be based on in-situ ice properties.
Moslet’s research is based on measurements of level ice on Svalbard and has three parts: Small-scale measurements of the ice properties and ice strength to better understand the relationship between the physical and mechanical ice properties and strength; measurement of ice load on a construction, and measurements of pressure caused by increased temperatures compared with metrological measurements, to improve the understanding of thermal expansion of ice and to better estimate the pressure on structures in landfast ice.
Moslet’s thesis has brought new data on ice properties and ice load on structures, and can in the long run contribute to better estimation of ice load on structures.
UNIS, Statoil, The Norwegian Research Council, Store Norske Spitsbergen Coal Company and the Norwegian Polar Institute have funded Moslet’s doctoral research.
The defense lecture will take place at the auditorium “Lassegrotta” on Monday, January 15 at 13:15. A trial lecture will be held at the same place at 10:15. Both lectures are open to the public.
