Fluid-structure interactions and wave energy

Fluid structure interactions

Our research has encompassed many projects associated with wave scattering by fixed and floating offshore platforms, relevant to investigations of loading, motion responses and local free surface behaviour. As part of this work the group has developed two major software tools:

  • DIFFRACT for linear and second order analysis in the frequency domain;
  • OXPOT for fully nonlinear potential flow analysis in the time domain.

Both have been associated with extensive validation through experiments and alternative modelling. Recent projects have focussed on Floating Production, Storage and Offloading systems (FPSOs); water projection beneath semisubmersibles in extreme conditions; the dynamics of coupled systems (in close association with the Centre for Offshore Research and Engineering at the National University of Singapore, where Prof Taylor and Prof Eatock Taylor are Visiting Professors); and wave energy (see below).

Wave energy

We are currently using both DIFFRACT and OXPOT (see above) in projects concerned with the effects of interactions in arrays of floating wave energy converters. Implications of wave directionality, different power take-off devices, and the complex phenomenon of “near wave trapping” are under investigation.
