Gravity Tripod Foundation Put through Paces

first_imgHydraulic engineering and offshore renewable energy specialist HR Wallingford is conducting physical model testing for a new offshore wind foundation known as the Gravity Tripod. The company is working with Offshore Design Engineering (ODE), DNV-GL, Cambridge University and the Offshore Renewable Energy (ORE) Catapult to test and certify the new offshore wind foundation concept designed by Offshore Wind Logistics and Construction (OWLC). The project is funded by the UK’s Department for Business, Energy and Industrial Strategy (BEIS).Matt Bleasdale, Director of OWLC, said: “The Gravity Tripod is a unique structure combining the best aspects of other foundation concepts into one low cost solution. It requires no piling, is low drag, low scour, and installed with minimal seabed intervention. The structure is able to accommodate turbines from 3 to 16 MWs, and, having been designed for low bearing pressures, is capable of accommodating a wider range of seabed types, with less seabed preparation, than other gravity base designs.”The Gravity Tripod foundation project will go through a series of stages, with certification from DNV, in preparation for demonstration of the design with a prototype structure.Design work and optimisation will be undertaken by ODE, with testing of the physical components conducted by ORE Catapult. Cambridge University will conduct geotechnical sediment modelling, looking at the interaction between the structure and sea bed.HR Wallingford will conduct physical model testing to investigate the loads applied to the structure during installation, those caused by exposure to large waves once the foundation is in place, and to determine the amount of erosion (scour) that may develop around the base of the structure if left unprotected.Dr David Todd, Business Development Manager for Research at HR Wallingford, said: “The foundation will be subjected to rigorous physical testing in the Fast Flow Facility, a unique wave-current-sediment flume designed for the offshore wind market, making it the ideal location for installation, survival and scour testing of offshore wind foundations.”last_img read more

DONEGAL U15s WIN FIRST ALL-IRELAND CAMOGIE TITLE

first_imgThe Donegal U15 team with their coaches and mentors.The Donegal U15 camogie team have made history by winning the county’s first All-Ireland at this level.The Donegal camogie girls and their mentors undertook the long journey to Trim, Co Meath on Saturday to participate in the All Ireland Tier 2 blitz competition.The girls were slow to start in the first match against Roscommon and conceded a late goal to finish in a draw 1-03 each.In the second match against Monaghan, Donegal found their rhythm and dispatched some great scores to win on a scoreline of 7-04 to 1-0. Wicklow were the next opponents and in a closely fought contest the Donegal girls dug deep to got some late scores and won 4-04 to 2-02. Donegal and Roscommon both finished on equal points and met again in the Shield final. This was a strongly contested match with two evenly matched teams. The half time score was 0-1 each.Donegal started the second half quickly and went two points ahead. However Roscommon came back and the defence battled to keep them out.In the last two minutes Donegal pushed on again and a goal from Captain Maria Coyle just before the final whistle ensured the Shield for Donegal.Caroline Murray, Camogie Association presented the Shield and medals to Maria Coyle. The squad of 19 girls from all over the county deserved their win on the day for their determination, work rate and spirit.
