Abstract
Based on a small prototype of the McCabe
wave pump device, this paper studies the optimal size
of an interconnected pontoon system, where the power
take-off systems attached to each barge are equipped with
optimal linear passive dampers. To this end, an optimization procedure is developed, where the objective is to
maximize the extracted energy of the device under given
sea states. A multi-DOF mathematical model is presented to
describe the device motion, and associated hydrodynamic
parameters are computed using a boundary element model
tool, based on linear potential flow theory. Numerical
results, under regular and irregular waves, are presented.
Simulation results show that the optimal dimension of
the device, under given sea states, can be found using
the developed methodology. In addition, it is found that
the three-body hinge-barge device tends to perform like
a two-body system under optimal control conditions. This
indicates that a two-barge control system may be a better
design solution in those situations, considering the high
cost of power take-off systems.
