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.

  • valid for whole curriculum period:

    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 for whole curriculum period:

    The assessment will consist of weekly exercises, 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. In addtion, iB excursion is possible, but most prpobably only part of the students will get allowannce and the criteria will be the success of the course progress

  • valid for whole curriculum period:

    On the final grade exam 100% contribution, in addition there is a minimum amount of weekly exercises (50%) the students have to conduct to get the permission for the exam and when all exam done properly, max 6 points added to the eaxm points

    Lectures: 3 h/week, 54 hours in total

    Exercises: 1 h/week, 48 hours in total

    Preparing for the exam: 24 hours
