Oscillating water column supporting structures: A review

Abstract

Numerous studies on the potential for wave energy in Indonesian waters have been conducted using Wave Energy Converter (WEC). One of the most extensively studied and developed wave energy conversion technologies is the Oscillating Water Column (OWC). Although OWC technology has the good potential, there are still several difficulties and problems that prevent its widespread development and use. One is the difficulty of keeping the systems working in hostile marine conditions. The supporting structure is an integral part of the design and operation of an OWC system. An OWC system's structural design must guarantee lifespan, stability, and dependability in a severe marine environment. More study is required to create durable and dependable systems, mainly supporting structures functioning in these conditions. This study reviews existing literature to analyse the structural strength of OWC systems, aiming to provide insights into methods for enhancing their durability and reliability, particularly in harsh marine conditions. Key findings include the classification of various supporting structure technologies used in OWC projects, providing insights into their effectiveness and applicability in different environmental settings. Moreover, the study emphasizes ongoing efforts to address obstacles limiting the widespread adoption of OWC technology, underscoring the need for further research and development.
