Non-linear Slack-Mooring Modelling of a Floating Two-Body Wave Energy Converter
Vicente, Pedro C.; Falcão, António de O.; Justino, Paulo AlexandreMost floating oscillating-body wave energy converters that have been proposed and developed so far are two-body systems where the power is extracted from the relative translational motion between the two bodies. As any floating device, floating point absorbers are subject to drift forces due to waves, currents and wind, and therefore need to be kept in place by a proper mooring system. The mooring cables can be...
Optimization of mooring configuration parameters of floating wave energy converts
Vicente, Pedro C.; Falcão, António de O.; Justino, Paulo AlexandreFloating point absorbers devices are a large class of wave energy converters for deployment offshore, typically in water depths between 40 and 100m. As floating oil and gas platforms,the devices are subject to drift forces due to waves, currents and wind, and therefore have to be kept in place by a proper mooring system. Although similarities can be found between the energy converting systems and floating platf...
A time domain analysis of arrays of floating point-absorber wave energy convert...
Vicente, Pedro C.; Falcão, António de O.; Justino, Paulo AlexandreThe extensive exploitation of the offshore wave energy resource may require the deployment of dense arrays of point absorbers, the distance between elements being possibly tens of meters. In such cases, it may be more convenient and economical that only elements in the periphery of the array are directly slack-moored to the sea bottom,while the other elements are prevented from drifting and colliding by connect...
Hydrodynamics of triangular-grid arrays of floating point-absorber wave energy ...
Vicente, Pedro C.; Falcão, António de O.; Gato, L.M.C.; Justino, Paulo AlexandreIt may be convenient that dense arrays of floating point absorbers are spread-moored to the sea bottom through only some of their elements (possibly located in the periphery), while the other array elements are prevented from drifting and colliding with each other by connections to adjacent elements. An array of identical floating point absorbers located at the grid points of an equilateral triangular grid is c...
