“…At early stages of device development, numerical models can allow rapid estimates of the energy capture performance of a device (Pizer, 1992;Josset et al, 2007;Payne et al, 2008;Kurniawan et al, 2011;Babarit et al, 2012), and provide powerful tools to gain insight in the behaviour of novel device configurations (Renzi and Dias, 2012;Alam, 2012;Farley et al, 2011;Lovas et al, 2010). The use of efficient numerical models allows extended parametric studies and optimization to be performed more rapidly than can be achieved experimentally (Malmo and Reitan, 1985;Babarit et al, 2005;Folley et al, 2007a,b;Vicente et al, 2009;Gomes et al, 2011;Oskamp and Ozkan-Haller, 2012;Falcao et al, 2012).…”

a b s t r a c tThis paper reviews key issues in the physical and numerical modelling of marine renewable energy systems, including wave energy devices, current turbines, and offshore wind turbines. The paper starts with an overview of the types of devices considered, and introduces some key studies in marine renewable energy modelling research. The development of new International Towing Tank Conference (ITTC) guidelines for model testing these devices is placed in the context of guidelines developed or under development by other international bodies as well as via research projects. Some particular challenges are introduced in the experimental and numerical modelling and testing of these devices, including the simulation of Power-Take-Off systems (PTOs) for physical models of all devices, approaches for numerical modelling of devices, and the correct modelling of wind load on offshore wind turbines. Finally, issues related to the uncertainty in performance prediction from model test results are discussed.

“…This is the remarkable case of the nodding Duck (created by Stephen Salter, from the University of Edinburgh) ,that has been appearing since the1970s and early1980s [15] ,that are probably the best known offshore devices among those, and which of several versions were developed in the following years [16]. One of the example of this oscillating-body systems is Searev Wave energy converter developed at Ecole Centrale de Nantes, France [17], it is a floating devices that consist of a heavy horizontal-axis wheel serving as an internal gravity reference (Fig. 6 (b)).…”

With considering the increasing of global temperature, and also the concern of global climate change, many policy makers worldwide have been accepted the importance of reducing greenhouse gas emissions, in particular from the power industries so the importance of the renewable energy is obvious. Wave energy is one of the renewable energy sources. And has the potential to play a valuable part in a sustainable energy future. Wave energy is also one of the predictable energy sources that depending on oscillating the surface of water. The wave energy system for generation electricity in the last few years has been growing rapidly. There are several methods that have been proposed to classify wave energy converters with considering working principle, location and size such as the oscillating water column (OWC), oscillating body systems, overtopping converters and etc. In almost every system, optimal wave energy absorption includes some kind of resonance, which implies that the geometry and size of the structure are linked to wavelength. The resonance allows to relatively small device to producing large power. This paper discusses about the various technology of wave energy converters.

“…Kurniawan and Moan (2013) stated that for geometry design of a WEC, especially wave absorbers, the minimum of submerged surface area, submerged volume, as well as the surface curvature will lead to the lowest construction cost as well as construction difficulty. Babarit et al (2005) conducted a geometric optimization of the SEAREV by focusing two objectives: to maximize the absorbed power at a given site and to minimize the total mass in order to minimize the cost. To simplify the multi-objective problem, some researchers consider two types of ratios as simple criteria for optimizing wave absorbers: the ratio of the submerged surface area to the absorbed power and the ratio of the reaction force to the absorbed power (French et al, 1996).…”

SeaWEED(Sea Wave Energy Extraction Device) is a multi-body floating wave energy converter (WEC) with hinged joints developed by Grey Island Energy Inc.(GIE) in Canada. Initial conceptual studies have been carried out to evaluate the performance of the first generation device by testing an 1:16 scale model in a wave basin. The experimental results were compared with the numerical solutions. Based on the experimental studies, improvements were made and a second generation model with a new geometry of the hull and a new connection structure was developed. This thesis is mainly focused on the numerical analysis and optimization of the second generation SeaWEED model. In the numerical studies, the hydraulic power take-off (PTO) system was simulated by a linear spring damper system coupled with the motion of the hinged bodies. The vertical hinge motion was computed at a series of wave periods using WAMIT. Optimization was focused on the PTO damping and the geometrical parameters in terms of the draft and the length of the truss structure between hinged bodies by using the response surface method. The optimization was conducted in regular waves and in irregular sea states. An optimal combination of length, draft and PTO damping was recommended for an intended operation location. Thanks to all the other colleagues in our group; we studied together, worked together; and I am glad to see that we all made big progress during the study in the Advanced Marine Hydrodynamics Laboratory.
