Bottom Founded Structures

Even today, the majority of new structures built in the sea are of this type. Their most common form is a steel truss structure supported by hollow steel piles driven into place just after the structure has been installed on the sea bed. There are a few thousand of these structures already in use around the world in water depths of up to about 500 meters.

A relatively new activity is the development of a single steel monopile structure to support wind turbines placed in offshore wind farms. Although these structures usually are of modest proportions, their design is just as challenging.

The core curriculum for bottom founded offshore structures consists of 3 subjects totaling 16ECTS. Including this into the offshore core curriculum gives 91ECTS including the thesis. This leaves 29 ECTS for elective courses. The core bottom founded offshore structures subjects are as follows:

Bottom Founded Offshore Structures - 6ECTS

During this course, students will perform a full cycle of the BFOS design process. At the start of the course, the students will gain a thorough theoretical understanding of the design process and its structuring, including an understanding of the philosophy behind the design codes. Then, by means of a large assignment, the students will design a bottom founded offshore platform and thereby learn how to apply the existing design codes. Throughout the assignment, students will judge their design and be able to modify and improve their design based on the knowledge gained from the lectures.

Structural Dynamics - 4ECTS

The goal of this course is to introduce various dynamic models of structures and to acquaint the students with the main ideas and methods of structural dynamics. The course prepares students to carry out dynamic response computations on structures that have distributed masses.

Floating Structures & Offshore Moorings - 6ECTS

The course provides an introduction to floating structure types used in the offshore oil, gas and renewables industry and an introduction to mooring systems for floating structures. 
The goal of this course is to familiarize the students with analysis techniques used in research and in the industry.
Central to the course are the equations of motions and the stochastic character of input (waves) and responses for single and multibody systems.
