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

After successfully completed the course the candidate has ability to assess the properties of ice as a material and make calculations of the loads of ice on structures in different iceinfested areas.Knowledge:Candidates should have knowledge of:- Different Sea Ice Features- Characteristics of the different Sea ice Features- Ice physics- Classical ice mechanics- Fracture mechanics of ice- Material modeling of ice- Type of structures used in ice- Mechanisms that cause vibration of structures exposed to iceSkills:The candidate is able to:- Make ice load calculations using numerical tools- Make assessments of ice loads based on physical testing in ice tanks- Assess the use of full-scale data in the ice tank testing- Suggest design engineering for the reduction of ice loads and vibrations caused by iceGeneral knowledge:The candidate has:- General knowledge of ice physics and mechanics- General skills that can be used for design of offshore structures in iceinfested areas

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. To pass the course a score of at least 70 percent is required.

Specific conditions

Admission to a programme of study is required:
Engineering (PHIV)

Required previous knowledge

The course will be run if at least 3 students with relevant background wish to attend. If you wish to attend, please contact the course coordinator. Students not admitted to the PhD programme in engineering may be approved by the course coordinator.
