DEME Offshore reaches milestone on wind farm

Published by

DEME Offshore has announced that its work on the foundation structures for the Moray East Offshore Wind Farm has reached a key milestone, with all 37 000 t of pin piles for the project now installed in the Moray Firth concession area.

Having designed the piles to contend with a complex and varied seabed geology, this stage of the project required DEME Offshore’s specialist installation vessel ‘Apollo’ to carefully drive each of the 309 piles into place within strict positional and vertical tolerances. This highly precise operation was achieved through the use of innovative pile engineering and the development of a patented piling template, designed to integrate with the jack-up legs of ‘Apollo’.

As well as this, DEME Offshore developed a special underwater drilling tool to cope with hard and rocky layers and relief drilling to install the piles in these challenging conditions.

DEME Offshore was supported by the services of a number of specialist UK companies, and particularly notes those which conducted heavy fabrication works at Arnish and Methil, and those that provided onshore logistical services via facilities at Invergordon.

DEME Offshore looks forward to the second stage of offshore works when its newbuild, next generation offshore installation vessel ‘Orion’ will integrate 103 jacket foundation structures and three topside modules with the pin piles now in place.
