HDD, A Key factor in the construction of Beatrice Wind Farm Project
22 November 2017
The Beatrice Offshore Wind Farm will be located on the north-western point of Smith Bank in the Outer Moray Firth, Scotland, approximately 13.5km away from the Caithness coastline. It will be comprised of 84 Siemens wind turbines, erected on jacket foundations, in ocean depths between 35 and 56 meters. Each of the turbines will produce 7MW. Upon completion, the project will generate 588MW of renewable electricity, which will be enough to meet the electricity needs of 450,000 UK households.
Eco Drill (England) Ltd were awarded the HDD sub-contract by the principal contractor, J Murphy & Son’s, on the Beatrice Offshore Windfarm.
Eco Drill have completed 16 of a planned 20 single bores and are currently set up for drilling at the Keith Dufftown private railway. They’ve been pilot boring with a Ditch Witch JT60 All Terrain Directional Drill. The next process of reaming the hole out to a larger diameter is achieved by utilising a Ditch Witch JT100 Directional Drill.
The final ream is with a 700mm hole opener, the rock is certainly taking a toll on the reamers and tooling. The product pipes to be installed into the 700mm bore cavity are 3x 225mm and 1x 125mm Polyethylene pipes.
This week should see the completion of the remaining water crossing with Network Rail and the final road crossing is planned for completion in January 2018.
Project Quick Facts:
-Beatrice, once fully operational, will be Scotland's largest offshore wind farm.
-Located approximately 13.5km from the Caithness coast, Beatrice will create around 90 full time roles for the duration of its 25-year lifespan.
-Onshore construction began in Moray in May 2016 and offshore construction began in April 2017.
-Beatrice will be energised in phases and will be fully operational in 2019.
