In order to be eligible for a second cycle course the applicant needs to fulfil the general and specific entry requirements of the programme that owns the course. (If the second cycle course is owned by a first cycle programme, second cycle entry requirements apply.)
Exemption from the eligibility requirement: Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling these requirements.

Course specific prerequisites

Mathematics (including probability, statistics and numerical analysis), mechanics and strength of materials and engineering materials.


The course gives students knowledge and tools about how to design marine structures using limit state based approaches by means of probability and risk analysis. A variety of simplistic and advanced methodologies are compared with objectives to demonstrate their advantages and limitations. Realistic and typical examples for marine structures are used throughout the course in order to introduce real examples to students with their challenges of complexity which require solid and well-motivated assumptions.

Learning outcomes (after completion of the course the student should be able to)


- show the ability to describe regular and irregular waves in the frequency domain
- show the ability to handle irregular waves from a statistical and probabilistic point of view
- show the ability to make simple estimates of wave induced loads on floating structures
- show the ability to make simple estimates of motions in waves
- show knowledge about derived responses in waves
- show the ability to estimate the probability of the derived responses
- show knowledge about extreme motion response in waves
- show the ability to use a modern computer software for ship motion analysis
- show knowledge on methods for ship manoeuvring analysis
- show knowledge about how to assess the course stability of a ship
- show knowledge how to analyze common ship manoeuvres
- show knowledge about background theory and simplifications for manoeuvring - show knowledge of steering devices - show knowledge about basic design principles for seakeeping and manoeuvring


- Waves, wave spectra, regular and irregular waves, wave statistics, probability
- Forces due to wave loads
. Equations of motion for a floating structure
- The seakeeping problem
- Equations and approximations for seakeeping
- Response due to wave loads in heave, pitch and roll for regular and irregular waves
- Frequency domain analysis
- Derived responses, velocities, accelerations, propeller emergence
- Slamming
- Parametric roll
- The manoeuvring problem
- Equations and approximations for manoeuvring
- Course stability
- Manoeuvring in deep and restricted water
- Propeller, rudders and thrusters for manoeuvring


The learning is accomplished by learning sessions where the contents of the course are presented together with examples, tutorials and the theoretical background. A computer software for ship motion analysis is introduced during the learning sessions. The software is used for an assignment on ship motions in waves. The learning is supported by visits to a wave laboratory and a ship manoeuvring simulator.
