NAREC WIND TURBINE DRIVE TRAIN TEST FACILITY
The UK National Renewable Energy Centre (NAREC) has been the driving force behind the creation of an offshore wind drive train test facility rated at 15 MW. IDOM’s engineering services comprised the design of the pile foundation, concrete superstructure, strengthened floor & anchoring systems, as well as the design of steel supports for the test piece, force application system and motor. These services were completed by a vibration transmission control analysis. On-site technical assistance was also provided during the whole fabrication, construction and assembly stages.
The UK National Renewable Energy Centre (NAREC) has been the driving force behind the creation of an offshore wind turbine test facility at its existing facilities in Blyth. This facility has the capacity to test the latest generation nacelles up to 15 MW (The FUJIN Project).
In the framework of this project, IDOM has been contracted by Shepherd Construction Ltd to take responsibility for the design of the foundations system, anchors and metal supports for the main elements of the facility.
The scope of the contract also included the provision of technical assistance during construction works as well as the assembly and installation of these elements.
The design consisted of 4 metre deep pile foundations (43 m X 12 m) – a 1600 m3 monolithic concrete slab which was poured continuously over 18 hours – various heavy metal supports anchored to the slab with pins of 100 mm in diameter.
One of the most notable features of the design is that it should not only be able to withstand considerable dynamic loads and fatigue, but also to achieve tight assembly tolerances.
