Graduation Thesis - Effect of Time - Varying Current Loads on Station Keeping

Are you looking for a challenging Master graduation assignment in which you can put your acquired knowledge and skills to the test? We can give you this challenge within our Marine Engineering team.


The Engineering department at HMC is responsible for the engineering of all our projects, from the installation or removal of fixed and floating platforms through to the installation of subsea pipelines and infrastructures. The department brings together people from a wide variety of technical and engineering disciplines. Within the Engineering Department Marine Engineering performs essential analyses and calculations for the transportation and installation of offshore structures. When working on location, they provide engineering support for the Vessel Management Team and the Project Team.

HMC consistently pushes the boundaries of what is possible in demanding marine conditions. We work on projects that pose unique planning and engineering challenges. Our clients rely on us to develop ground?breaking solutions. Therefore we are currently looking for a talented Master student with a hands?on mentality for our Marine Engineering team.

Graduation Assignment
Dynamic Positioning (DP) is the main method for station keeping of HMC's vessels during offshore operations. During project preparations, DP capacity assessments are performed using numerical models, while the actual performance of the system during execution is monitored and logged. Systematically comparing and analyzing these two improves the models.
A possible improvement is taking into account the effect of non-stationary current loads. This non-stationary character of current loading can originate from the space-time variation of current itself, as well as from vortex shedding of a current flow from the hull. It is possible that both effects are also dependent on water depth.

The goal of this graduation thesis is to determine the presence and effect of non-stationary current loading on the DP-footprint of SSCV Thialf.

You are a highly motivated and enthusiastic student who can contribute to solutions to our current and future challenges. Ideally we are interested in the following profile:

  • Master student who is enrolled in a Maritime / Offshore or comparable Engineering program;
  • Keen interest in hydrodynamics and station keeping (DP);
  • Knowledge of / experience with Matlab or Python;
  • Strong analytical mindset;
  • Critical thinker with excellent problem solving skills;
  • Independent and enjoys working together;
  • Urge to deliver quality and take ownership;
  • Strong verbal and written communication skills in English and Dutch.
