Teaching Period (valid 01.08.2018-31.07.2020): 


Learning Outcomes (valid 01.08.2018-31.07.2020): 

The aim is to introduce the student to winter navigation system in the Baltic Sea and basic principles for ship power requirements and hull ice-strengthening. After the course, students understand the definition of various ice conditions and their effects on the ship design, hull shape, power requirements, navigation in ice and safety of ships. Power requirements needs a comprehensive knowledge of the various methods to calculate the ship resistance in varying ice conditions such as level ice, ridged ice and ice channels. For the hull design, most important is to know how to calculate the ice induced loads on the hull. In addition the principles of model scale testing in ice are introduced.

Content (valid 01.08.2018-31.07.2020): 

Winter navigation system in the Baltic Sea, definition ice conditions, ice mechanical properties, ship resistance in various ice conditions, propulsion in ice, power requirements, ice induced loads on ships, ice strengthening principles for ship hull. Excursion to an icebreaker operating in the northern Baltic Sea.

Assessment Methods and Criteria (valid 01.08.2018-31.07.2020): 

The assessment will consist of weekly exercises, the group work and the exam. Weekly exercises are related to the topics presented in the lectures and they will give the students skills to conduct the important ship design related tasks. Group work will be based on the full scale observations conducted during the visit to the icebreaker in real operations and the idea is to apply the theoretical to simulate ship performance in ice and compare those with the full scale observations onboard the icebreaker.

Workload (valid 01.08.2018-31.07.2020): 

On the final grade group work is 30 % and exam 70% contribution, in addition there is a minimum amount of weekly exercises (50%) the students have to conduct to get the permission for the exam.
