Offshore Windfarm

Aarsleff Ground Engineering has recently completed piling for a new substation as part of the Triton Knoll Offshore windfarm project in Bicker Fen, Boston.

The new substation, which is connected to the windfarm via 40 miles of underground cable to the Lincolnshire coast, will convert the generated electricity from the windfarm for the National Grid.

Once completed, the windfarm will be capable of providing clean and sustainable energy to over 800,000 UK homes.

Aarsleff Ground Engineering previously installed over 1500No.200mm and 250mm square precast concrete piles in April for the foundations of the substation buildings and equipment.

Subsequently, Siemens awarded Aarsleff the piling works for a gas main bridge that crossed the 3.8km access road.

The project saw Aarsleff install 8no. 600mm diameter CFA piles of 15m lengths, which were located either side of the gas main.

CFA piles were specified due to minimal vibrations it creates as the piles are being
installed. Siemens then laid a concrete slab to create a bridge over the gas main and prevent any future damage from service vehicles and machinery driving down the access road.
