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 ocean 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

After completion of the course the students shall have knowledge and skills to carry out basic tasks regarding structural design and dimensioning of marine structures. The students shall be able
- Describe the layout of marine structures from a functional and safety requirements point of view
- Conduct fundamental global stability checks of various floating and bottom supported offshore structures
- Describe the fatigue limit state and ultimate limit design format
- Describe relevant resistance formulation for FLS and ULS design of beam-columns, stiffened plates and shells
- Conduct simple calculation of the resistance against accidental actions, notably collisions, explosions and fires
- Conduct hydrodynamic analysis of floating platform and Interpret transfer functions and extreme response statistics on the basis of a thorough understanding of the governing physical effects
- Perform time domain, extreme response analysis of a jacket in irregular seas using the computer code USFOS and write a technical report of the investigation
- Understand and describe the difference between deterministic and stochastic response analysis
- Find and understand important recommendations in standards and recommended practices regarding environmental conditions and load estimation.
- Predict characteristic environmental parameters corresponding to different annual exceedance probabilities
- Switch from annual target probabilities to t-hour exceedance probability
- Perform design wave analysis
- Perform long-term response analysis by
i) all sea states approach i
ii) random storm (POT) approach
- Estimate long-term extremes using short term method (environmental contour line approach).

Learning methods and activities

Lectures,exercises, mandatory project work using USFOS software. A mandatory 2 x 2 full day course in use of the SESAM system (WADAM, GENIE) may be included in the exercises. This subject is taught in the international M.Sc.program every second year. Exercises and lectures are normally conducted in English.

Compulsory assignments

  • Exercises

Further on evaluation

Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam (60%) and exercises (40%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade.
Examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
Postponed/repeated exams may be oral.
For a re-take of an examination, all assessments during the course must be re-taken.

Required previous knowledge

Structural analysis, finite element analysis, sea loads, probability concepts, statistical methods, stochastic analysis.
