Site Preparation
In anticipation of the SeaGen installation in April 2008, the Horizontal Directional Drilled (HDD) bore hole for the power cable was been completed in June 2007, and the substation was completed in April 2008.

The SeaGen system will be connected to an existing grid connection adjacent to the sewerage substation south of Strangford in 2008 and first exported the full 1.2MW capacity in December 2008..
A 450m long HDD bore hole 300mm diameter was drilled 20m below the seabed so that during installation the 11kV power cable could be pulled through the duct.
In February 2008 temporary sub sea mooring piles were installed to anchor the construction vessels to. These will remain in place until SeaGen is decommissioned.
