... Abstract In ISO19906 (2010) (Arctic Offshore Structures) specific algorithms are provided for level ice loads on sloping structures; they are based on the separate work of Ralston and Croasdale. These methods were developed decades ago and comparisons with full scale data, especially from...

... can be estimated using a variety of methods [ Croasdale, 1980 )], [ Nordgren and Winker (1989 )], [ Wang (1984 )]. " A study was undertaken to revisit the theories for breaking and ride-up of MY ridges and if possible to improve them. A new simplified method for long ridges has been developed which...
