Fonseca, N., Pessoa, J., Pascoal, R., Morais, T. e Dias, R. (2010), “Design Pressure Distributions on the Hull of the FLOW Wave Energy Converter”, Ocean Engineering, Volume 37, pp. 611-626

This paper presents aprocedure to calculate the design pressure distributions on the hull of a wave energy converter (WEC). Design pressures are the maximum pressure values that the device is expected to experience during its operation all if e time. The procedure is applied to the prototype under development by Martifer Energy (FLOW Future Life in Ocean Waves). A boundary integral method is used to solve the hydrodynamic problem. The hydrodynamic pressures are combined with the hydrostatic ones and thein ternal pressures of the large ballasttanks. The first step consists of validating the numerical results of motions by comparison with measured experimental data obtained with a scaled model of the WEC. The numerical model is tuned by adjusting the damping of the device rotational motions and the equivalent damping and stiffnes softhe power take-off system. The pressure distributions are calculated for all irregular sea states epresentative of the Portuguese Pilot Zone where the prototype will be installed and alongt erm distribution method is used to calculate the expected maximum pressures on the hull corresponding to the 100 - yearre turn period.
