Decommissioning Penguin WEC 1 and Mooring Components

Abstract

Project Information Summary 

Through the Horizon 2020 Clean Energy from Ocean Waves (CEFOW) project, Wello developed the Penguin device and successfully installed the wave energy converter at the European Marine Energy Centre (EMEC) in 2017. The device underwent a successful testing campaign and remained on site for over two years. In March 2019, the device’s integrity was undermined the device begun to take on water. The floating device sunk to the seabed where it has been regular monitored, when weather and sea conditions have allowed. This document has been produced has a project summary to support a marine licence application in order to remove the device from the seabed and return to shore. The work is anticipated to take place during summer 2020. The removal work is currently being tendering through a rigorous procurement process and a marine contractor is expected to be selected shortly.  Once the contractor has been selected further details regarding the removal method and vessel spread will be available. A high-level method statement has been produced as an accompanying document to this project summary.  As lead partner to the CEFOW project, Fortum Energy UK is completing the removal work.  

Environmental Report and Monitoring Programme

This programme has been developed as an addendum to the Environmental Report and   Environmental Monitoring Programme submitted in July 2018 as part of the overarching marine licence application to deploy and operate a three-device array. The array was planned to be composed of three Penguin devices developed by Wello Oy and owned by Fortum Energy UK through the Horizon 2020 Clean Energy from Ocean Waves (CEFOW) project.   This programme reviews the potential environmental risks associated with the removal of the Penguin WEC 1 from the seabed and the removal of mooring components. The report is based on EMEC’s site-wide Environmental Appraisal for the Billia Croo test site and therefore it is recommended that the appraisal in read concurrently to this report. The proposed mitigation and monitoring measures that are planned to be employed during the works are also described within the programme.
