dc.description.abstract
Numerical models of wave energy converters (WECs) have been successfully used
since the 1970s to understand a device’s characteristics and improve its performance
before advancing to costlier, higher-risk stages of development such as tank testing
and sea trials. In the last decade several software packages have become available to
the industry specifically for time-domain multibody WEC modelling using potential
flow theory. One of these tools is InWave, developed by Innosea, which is based on
a reduced-coordinate multibody dynamics solver. However, one of the main challenges
in developing a WEC modelling tool is the fact that the wave energy sector has
not yet converged on a particular technology and there are many different designs
currently in development, featuring a wide range of working principles. This thesis
presents a novel WEC modelling tool: InWave-HOTINT, which uses a third-party
multibody dynamics code (HOTINT) based on a redundant coordinate multibody dynamics
method. This approach enables InWave-HOTINT to model a much wider range
of mechanical topologies - including WECs featuring closed mechanical loops, multi-
DoF PTOs and net mooring systems. The thesis describes the development and verification
of the tool, as well as a demonstration of some of the new capabilities via a
model based on the Albatern S12 WEC.
