Course content

The course addresses the molecular structure of ice, the formation, growth and classification of ice. Rheological properties of ice are presented, stress-strain relations, temperature effects and fracture mechanical behaviour. Ice conditions in cold waters of interest for the oil industry are described. Further, ice-structure interaction is highlihted with emphasis on analytical, empirical and numerical calculations of loads from sea ice on fixed and floating structures.

Learning outcome

The purpose of the course is to give the student an introduction to physical and mechanical properties of ice and loads ice may exert on marine structures.

Learning methods and activities

The course consists of a lectured part and project work. The project work shall lead to a report that accounts 40 % of the exam. The report shall be delivered latest one week before the exam. Questions to the report may be raised during the examination.
