Course content

The extent of the various subjects lectured may vary from one year to the other, but will typically comprise: Serviceability and safety design criteria, including requirements to overall stability and strength as well as evacuation and escape. Design rules for offshore structures including offshore wind turbines. Overview of functional, environmental and accidental loads for marine structures, with emphasis on wind - and wave induced loads. Methods for calculating characteristic natural loads with emphasis on use of statistical methods. Stochastic response analysis, long term response analysis, environmental contour method. Nonlinear, time domain simulation of offshore structures and wind turbines subjected to extreme environmental actions. Limit state design checks. Structural resistance against accidental actions-; fires, explosions, ship collision. Materials for marine structures. Alternative designs of facilities for the offshore oil and gas industry.

Learning outcome

Provide the candidate with the knowledge and skills to carry out basic tasks regarding structural design and dimensioning of marine structures.

Learning methods and activities

Lectures,exercises, mandatory project work using USFOS software . This subject is taught in the international M.Sc.program every second year. Exercises and lectures are normally conducted in English. Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam (60%) and exercises (40%). A mandatory 2 x 2 full day course in use of the SESAM system (WADAM, GENIE) may be included in the exercises. The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade. Postponed/repeated exams may be oral. Examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
