Course content

Structure design is, in this course, defined as design of load bearing structures Offshore.

The subject aims to teach the students to do design load bearing structures, with respect of dimensions and material quality.

Key words: analysis, drawings, etc. for fabrication, assembly, erection, maintenance and inspection. This structures design course focus on structural steel as construction material

Module 1 : Introduction to -Offshore Structures

Module 2 : NORSOK Overview Material selections Terms, definition ( Design class I, II, ... etc.) Overview load conditions (ULS, FLS, ALS)

Module 3 : Design of steel structures according to NORSOK and Eurocode. Plated, trusses and frame structural elements Design of bolted and welded joints

Module 4: Practical 3D CAD exercises with supervision

Module 5: Practical analysis exercises with supervision

Modul 6: Wind wave and current evaluations

Modul 7. Stability evaluations

Learning outcome
