An n-body displacement framework for marine hydrodynamics Conference Paper uri icon


  • The wide variability of ocean platform designs, the increasingly common specification of multi-body configurations, and the random nature of the offshore environment present some interesting challenges. Experience with models of a single platform or a ship is well established and has provided an important linkage for the engineer to evaluate a design concept and provide a basis for design modifications prior to construction and installation offshore. The use of multiple models, i.e. n-bodies, in model tests is not new, but the procedures used in the analysis of the data are still evolving. This study presents a framework to study the data from n-body measurements and encompasses a wide range of offshore environments used in design. In order to illustrate the methodology experimental data for a two-body problem involving the coupled motion behaviour of a mini-TLP and tender barge subject to random waves is investigated. The selection of reference and relative scaling values are illustrated and discussed. 2009 WIT Press.
