Spanish tidal energy developer Magallanes Renovables has returned to the EMEC: European Marine Energy Centre tidal test site in Orkney for the re-installation of its turbine following upgrades.
Magallanes’ second-generation 2MW tidal platform, ATIR, was reinstalled last week following removal for maintenance and optimisation. The Magallanes team worked in collaboration with Orkney-based marine service provider Leask Marine Ltd, along with the Orkney Harbour Authority tug Thor, to install the platform in an operation lasting eight hours.
In order to optimise the performance the platform was transported to the dry dock of Dales Marine Services Ltd for maintenance, supported by GAP, Leask Marine Ltd, Briggs Marine & Forth Ports Limited.
The maintenance involved having to position the platform horizontally in the sea by using a system of buoys to fit into the dry dock via the locks. During this positioning operation in Leith, maintenance tasks were carried out to optimise the platform, including anti-fouling & performance verification, to allow the platform to operate more efficiently.
