Arctic and Marine Civil Engineering

Marine physical processes. Description of waves, currents, wind and formation and mechanics of ice. Resulting consequences for marine activities. Fundamentals of statistical methods used in physical marine environment.

Knowledge of:

The student should have knowledge of:

• Spectra of wind, wind forces and structural response
• Vertical wind profile
• Linear wave theory - wave kinematics and dynamics
• Wave statistics including wave spectrum
• Wave forces
• Ice conditions in the Barents Sea
• Some basic conditions of sea ice physics
• Methods for calculating ice loads from level ice on marine structures with oblique and vertical waterline (application of ISO 19906)
• Physical phenomena regarding vertical deformation of floating ice sheets (carrying capacity)
• Assumptions behind the mathematical models to calculate the carrying capacity of floating ice sheets

Skills:

The student is able to:

• Make simple calculations with the static wind load
• Apply the wind profile, extrapolate vertically and discuss wind force and structural response
• Calculate the movement of non-breaking surface waves on water, according to linear wave theory, and the impact from such waves on vertical walls and circular-cylindrical structures
• Interpreting a directional spectrum of waves
• Calculate sea state parameters from time series of waves - wave-to-wave analysis
• Estimate the extreme values ​​for marine environmental parameters on the basis of long-term measurements
• Calculate how regular waves change height, length and direction as they propagate into the shallow water against a coast with straight and parallel bottom contours
• Assess the local ice conditions in the Barents Sea
• Calculate ice growth and estimate ice thickness of floating ice
• Using ISO 19906 and estimate forces from level ice on marine structures with oblique and vertical waterline
• Consider safety with respect to the carrying capacity of floating ice sheets (operations and transport)

General qualifications:

The student has:

• Basics to read, understand and apply key guidelines, standards and recommended practices for design and dimensioning in the field of marine civil engineering
• A good background to be able to communicate with experts in the disciplines of oceanography, meteorology and arctic technology
