Arup is to undertake two significant studies for Wave Energy Scotland (WES) to identify alternative material choices for wave energy conversion devices.

For the first study Arup is undertaking a detailed engineering design assessment to better understand the potential for concrete to become the main structural material for wave energy conversion devices. The team expects to confirm the potential for concrete to bring about a step change in the levelised cost of electricity (LCoE) of wave power. Arup is leading the study, with participation from Cruz Atcheson, Sea Power, Wello and British Precast, to identify where structural concrete could have the greatest impact before progressing to develop a Front End Engineering Design (FEED) solution.

For the second study, Arup is supporting Cruz Atcheson in its assessment of hybrid structures with reinforced polymers as the main structural material. The project aims to better understand the use of reinforced polymers as the structural material for the prime mover of point absorbers. Arup will be undertaking structural analysis and providing composite design support.

On both projects Arup will apply its experience of designing complex, offshore structures in challenging environments. The team will draw on recent guidance in Wave Energy Scotland’s Forces & Stresses Landscaping Study, recently delivered by Arup and Cruz Atcheson.

 “Wave Energy Scotland is pleased that the programme will benefit from Arup’s considerable wealth of knowledge about structural materials and manufacturing processes,” said Tim Hurst, Managing Director, Wave Energy Scotland. “I am looking forward to hearing the conclusions from these studies and the materials’ applicability to wave energy converters.”

 “We are focused on finding a step change solution for wave energy conversion devices to help wave power reach its potential both off the coast of Scotland and worldwide,” added Jacob Ahlqvist, Arup Project Manager. “In our work with Wave Energy Scotland we will be drawing on decades of experience designing offshore structures and working with a range of materials in harsh environments.”
