Model testst in Concept basin,
As part of the Blue Mining project MARIN has conducted model tests in their Concept Basin. Aim of the model test was to determine hydrodynamic loads on typical riser sections and a pumping station (see Figure ).
This is achieved by three different tests:
1 tow tests to determine drag loads,
2 oscillations in still water, which is important for e.g. the estimation of the damping of vibrations and
3 towing with oscillations to determine the excitation levels of vibrations in the risers.
The resulting force coefficients will be used in computations that simulate the overall riser dynamics.
