“…Debido a que los costos de inversión requeridos para la puesta en marcha son elevados, es útil disponer de estimaciones de potencia de salida [35]{Reikard, 2015, Simulating and forecasting ocean wave energy in western Canada}, que considere localidades en donde se emplazará y características morfológicas de la costa y del suelo marino, ya que dependiendo de éstas la distribución energética se presenta de manera particular [31]. Además, otros focos que no han sido abordados son la incertidumbre sobre el impacto generado por las granjas de olas en el mar y la costa [36][37][38][39][40][41][42][43][44][45][46] o el hecho de que se considere poco rentable [32].…”

RESUMENLas energías marinas están siendo cada vez más consideradas en el mundo como un recurso importante y prometedor. Unas de ellas, la energía undimotriz, utiliza la energía mecánica proveniente del movimiento de las olas del mar para la generación de electricidad. Este artículo presenta una revisión bibliográfica de las siguientes temáticas: situación energética mundial, beneficios en la recolección de energía undimotriz y tipos de convertidores utilizados actualmente. Chile presenta una situación energética que requiere el uso de nuevas tecnologías. La región de Tarapacá posee un potencial considerable de generación de electricidad por medio de las olas, por lo que el aprovechamiento de este tipo de energía se presenta como una opción altamente vinculante con las industrias que forman parte del motor económico de la región.Palabras clave: Energía, ERNC, energía undimotriz, potencial undimotriz, convertidor undimotriz, potencial eléctrico, fomento productivo, región de Tarapacá, Chile.

“…Wave energy resource assessments have been an important factor for wave energy developments in recent years, and the focus has been on the assessment and characterisation of wave energy resources [1][2][3][4][5][6][7][8][9][10][11][12][13], with the global wave energy resource assessments on the overall resources and the distributions of wave energy [3][4][5][6], and the regional and national wave energy resources on the potentials for developing wave energy [7][8][9][10][11][12][13]. As pointed out by Cahill et al [7], the primary purpose of these studies is to examine the available potential energy at the locations of interest, and of the seasonal and annual trends in the resources.…”

A Method for Energy and Resource Assessment of Waves in Finite Water Depths

This paper presents a new method for improving the assessment of energy and resources of waves in the cases of finite water depths in which the historical and some ongoing sea wave measurements are simply given in forms of scatter diagrams or the forms of (significant) wave heights and the relevant statistical wave periods, whilst the detailed spectrum information has been discarded, thus no longer available for the purpose of analysis. As a result of such simplified wave data, the assessment for embracing the effects of water depths on wave energy and resources becomes either difficult or inaccurate. In many practical cases, the effects of water depths are simply ignored because the formulas for deep-water waves are frequently employed. This simplification may cause large energy under-estimations for the sea waves in finite water depths. To improve the wave energy assessment for such much-simplified wave data, an approximate method is proposed for approximating the effect of water depth in this research, for which the wave energy period or the calculated peak period can be taken as the reference period for implementing the approximation. The examples for both theoretical and measured spectra show that the proposed method can significantly reduce the errors on wave energy assessment due to the approximations and inclusions of the effects of finite water depths.

“…Most commonly the site assessment is based on either field measurements or numerical modelling or both. Large scale studies can either be on a global level providing information on the global wave energy resource and the distribution of wave energy [1][2][3][4], or on a regional level where national wave energy resources are assessed [5][6][7][8][9][10][11][12][13][14]. From such types of studies, the global offshore wave power is estimated at 32,000 TWh/year [2], and the availability of wave energy resources can vary significantly.…”

For cost savings and ease of operation, nearshore regions have been considered as ideal regions for deploying wave energy converters (WECs) and wave farms. As the water depths of these regions may be frequently limited to 50 m or less, they can be considered as being transitional/intermediate to shallow when compared to the wave lengths of interest for wave energy conversion. Since the impact of water depths on propagation of waves is significant, it cannot be ignored in wave energy assessment. According to the basic wave theory, in order to work out accurate wave energy amounts in finite water depth, detailed wave spectral distributions should be given. However, for some practical reasons, there are still some cases where only scatter diagrams and/or the statistical wave parameters are available, whilst the detailed wave spectra are discarded. As a result, the assessments of wave energy and resources are frequently determined by ignoring the effect of water depths or using very simplified approximations. This research paper aims to develop more accurate approximation methods by utilising a number of available parameters such that a better estimate on the wave resource assessment can be achieved even if the detailed wave spectra are not available. As one important goal, the research can provide some important indications on how the measured wave data are effectively presented so that they can be very useful for assessing the wave energy resource, especially in the cases including the effects of finite water depths.
