Carnegie: Perth Project Offshore Foundations Installation Complete

Carnegie Wave Energy Limited concluded the offshore foundation installation activities for the Perth Project off Garden Island, Western Australia.

The subsea drilling and installation of all pile type foundations has been successfully completed with the third and final pile completed over the weekend. The installation vessel will be demobilising from the site this week clearing the way for offshore pipeline lay to commence.

Carnegie advised in December 2013 that the foundation installation vessel, the Endeavour (previously named the Eunsung 1200), was mobilised with all foundations and installation equipment sea fastened on the vessel. The foundation installation vessel was then mobilised offshore to the Project site where installation activities commenced.

Onsite activities confirmed the geotechnical conditions, suitability of the pile design and the installation approach. Work was also carried out on improving accessibility to the installation vessel via preparing the vessel for helicopter transfer of the work crew. After a Christmas to New Year break, drilling and grouting of the pile foundations commenced with the third and final pile installation completed over the weekend.

Carnegie Project Engineer Neil de Tisi said: “The relationship developed between Carnegie and Fugro Seacore Pty Ltd has been integral to the successful installation of the foundations. I’m pleased we were able to work together to find solutions to the inevitable challenges that one encounters with these sorts of offshore activities and to successfully complete the installation of all foundations.”
