School exam 100/100 4 hours G

### Course content

Methods and principles for estimation and calculation of ice action on Arctic Marine structures, both offshore and coastal. Both bottom fixed and floating structures will be treated.

The course has four basic parts:

a) Ice actions on ships and floating structures, moored and non-moored including hydrodynamic effects

b) Ice actions on bottom fixed structures, in particularly ice-induced vibrations

c) Ice actions from ice ridges

d) Scale-model experiments for Arctic structures and ships

A short introduction to the relevant ice parameters/ice environment, a thorough description and discussion of the assumptions behind all model will be given, including the deformation pattern of the ice and its interaction with the structure.

Both simple engineering models and advanced models will be described and discussed.

The difference between ice actions and actions from waves and wind will be stressed.

### Learning outcome

The students shall have a general knowledge and competence about:

• Standard methods to estimate ice actions on fixed, floating and coastal Arctic structures.
• Fundamental assumptions and limitations of the Standard methods.
• Advanced model for estimation/calculation of actions from the Arctic Marine environment.
• Fundamental principles and practical solutions for scale-model testing with sea ice

### Learning methods and activities

Lectures and mandatory exercises. 8 exercises needs to be approved

• Exercises

### Further on evaluation

If there is a re-sit exam, the examination form may be changed from written to oral.

### Required previous knowledge

Basic engineering mathematics, statistics and mechanics corresponding to a BSc within Civil Engineering, Marine/Maritime engineering or mechanical engineering.

### Course materials

Compendias and articles.
