GREEN MARINE Safely deploy wave energy device

Over the 4th and 5th of March 2017 Green Marine successfully deployed the Wello Oy wave energy device (Penguin) at the European Marine Energy Centre's wave test site at Billia Croo in the Orkney Islands. The 1600-tonne Penguin device is around 30 meters long, nine metres in height and has a draft of around seven meters. Only two meters are visible above the water surface.

Following the construction of EMEC's wave test site in 2011, the Penguin was initially deployed at Billia Croo in the summer of 2012 for its first full-scale sea trials and grid connection. After this initial testing, the Penguin left Orkney for some modification and maintenance work.

Following a programme of modification and refurbishment in 2016, the Penguin returned to Orkney waters in 2017 and after careful preparations at Hatston Pier, Kirkwall, Green Marine carried out the deployment and installation at the wave test site at Billia Croo on Orkney's west coast.

Great care was taken to ensure all was safe and secure for the overnight transit from Hatston Pier to Billia Croo. Green Marine's vessels Green Chief and Green Isle towed the Penguin out to site and carried out the installation.
