First Turbine Foundation Has Been Designed and Constructed by Royal BAM Group

The first turbine foundation that has been designed and constructed by Royal BAM Group has started its journey towards installation as a part of the Blyth Offshore Demonstration Wind Farm project. The turbine foundation has been constructed at the dry dock in Walker, Tyneside and will then be transported up the River Tyne in order to be installed just off the coast of Blyth. The foundations are being constructed as part of a cutting edge wind farm development operated by EDF Energy Renewables. EDF acquired the project from Narec, now called ORE Catapult in October 2014 and has been working ever since in order to install five turbines that will be powerful enough to generate 41.5MW of power. The wind farm will be located 6.5km away from the coast in Blyth and it has been estimated using the capacity of the turbines that the farm will be able to generate enough low-carbon electricity in order to provide power to 34,000 homes. The concrete gravity based foundations, or GBFs that have been constructed as part of this wind farm project will make up the first part of the construction. The foundations will be installed using the float and submerge method, the first time for an offshore wind turbine construction project. Over the course of the past 12 months BAM Nuttall has been working on creating these foundations at the Neptune dry dock. However, yesterday, the 11th July, it was announced that the first foundation was on its across the River Tyne to the installation site. It is thought that each of the foundations that are being constructed as a part of the project to build an offshore wind farm weighs more than 15,000 tonnes when they are properly installed on the seabed. There will be a distance between the base and the access platform is 60m. Once the foundations have been installed, cables will be buried into the seabed that will then be connected to each of the turbines.
