Abstract
This study is an experimental study corresponding to an analytical study presented previously, where a scaled-down model was built and tested in a water tank by following the size and shape of the structure applied in the analytical study. In this study, a wave energy converter of an oscillating water column (OWC) system is integrated with the infrastructure of a jacket-type offshore platform applied to an offshore wind turbine system. The purpose is to conduct a combination system through the simultaneous utilization of both wind power and wave power so that sustainable energy can be maximized. During the analytical study’s analysis, the airflow response and the converting efficiency of wave energy from an OWC system integrated with an offshore template structural system were evaluated. By following the analytical study’s analysis, the performance of all the systems is tested, including the airflow velocity, pneumatic power, and the converting efficiency of the power from waves. The experimental data are analyzed and discussed in terms of the variations of the OWC system’s geometrical parameters. The parameters under consideration include the exhale orifice-area of airflow, gate-openings of inflow water, and the submerged chamber depth. It is found from the experimental results that, through the comparison between the experimental data and the analytical results, the results of the analytical study’s analysis are countable, and an open sea OWC system can be successfully applied to the template structure of offshore wind power infrastructure as a secondary generating system for the multi-purpose utilization of the structure.
Highlights
Alternative means for the replacement of fossil fuels for electricity generation have been commonly accepted since severe climate change has induced enormous environmental impacts and caused dramatic disasters around the world
As introduced in the analytical results in Lee et al 2021, the parameters chosen in the analysis are basically related to the dimensions of the air chamber for the oscillating water column (OWC) converter that was situated on an offshore template structure
By following the analytical study, in the experimental test of the OWC system for the converting efficiency the responses to be discussed include the velocity of the airflow through the orifice, the power produced by the airflow, and the converting efficiency in terms of the ratio of the pneumatic power and power of incident waves
Summary
Alternative means for the replacement of fossil fuels for electricity generation have been commonly accepted since severe climate change has induced enormous environmental impacts and caused dramatic disasters around the world. Similar to the analytical study, the parameters to be examined in this experimental test of the performing efficiency of the OWC wave converter integrated in the offshore template structure will include variations in the orifice, the size of the air chamber in terms of its height, and the openings of the gate facing the incident waves. All of these parameters are presented in dimensionless form. It is noticed that due to the limit of the water depth and the relative size of the structure, the wave height is limited within a range for the simulated waves applied to the experiment
