Specific course information
Brief description  :

This course contains the definition and introduction to offshore structure, types, offshore structure system, integrated design of offshore structure (considering creation, mobilization, installation, and operational stages), repetition/deepening of several related topics i.e. hydrodynamics (fluid flow behavior, structure dynamic response due to wave force, random sea wave analysis, fatigue effect in material mechanics properties especially steel), buckling effect especially pipe section member, marine structure foundation, steel and reinforced concrete corrosion in saline environment, construction method, feasibility evaluation of offshore structure

Prerequisite Courses :

Calculus, Chemistry for Civil Engineering, Hydraulics, Statics, Steel Structure, Reinforced Concrete Structure, Structural Dynamics Analysis and Earthquake Engineering.

Required/elective : Elective
Studio work : N/A
Laboratory work : N/A
Specific goals of the course
Specific outcomes :

The students are expected to be able to apply knowledge in mathematics, solve practical problems in analysis and design of simple offshore structure from production stage to installation and operational stage.

Student outcomes :

(c)  An ability to design a system, component, or process in order to be able to face the real constraints in economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability

(e)  An ability to identify, formulate, and solve civil engineering problems by considering local resources

(j)   Knowledge of contemporary issues in civil engineering

(k)  An ability to use the techniques, skills, and modern engineering tools for civil engineering practice
