■ Renewable Energy Project – Gwynt y Môr Offshore Wind Farm
■ 164 Electric Wire Rope Hoists Supplied to Granada Material Handling for Offshore Foundation Crane Systems
Lifting equipment manufacturer, Demag Cranes & Components Ltd, has won an order from Granada Material Handling Ltd to supply 164 electric wire rope hoists for a renewable energy project. The order comes in the wake of a contract, awarded to Granada by RWE npower renewables, to design, supply, third party certify, deliver, test and commission crane systems for the new Gwynt y Môr offshore wind farm.
Granada has incorporated the Demag hoist within its specially designed “Python” Crane system, which will be mounted on the foundation platform of wind turbines and each of two substations in the offshore wind farm. The “Python” units have been developed for offloading heavy service components from supply vessels to the lay down areas of the offshore structures. The driving factors in the development of the crane units have been health & safety, functionality and ease of use for operators.
The 1.3 tonne SWL Demag FDR PRO 5 electric wire rope hoists have been designed to meet the requirements of the offshore application and incorporate a range of features. Hoist stability, slow lifting speeds for precision handling, fast lifting speeds for load take off and a 24 metre height of lift ensure precise hook positioning for simple and safe unloading of supply vessels, even in rough sea conditions. The hoists feature IP65 rated enclosures and an offshore specification C5M paint finish to withstand the ingress of water and salt in the arduous marine environment.
Mark Sidwell, director of Granada Material Handling Ltd, stated:
“We have had previous happy experience of working with Demag Cranes on similar offshore wind farm projects. We have worked closely with Demag Cranes in the development of a material handling solution, which meets the specific requirements of the Gwynt y Môr project. The company’s depth of technical expertise has complemented the skills of our own renewable product and service division.”
Thomas H. Hagen, Member of the Management Board of Demag Cranes AG and COO added:
“With the solutions and products of our two strong brands, Demag and Gottwald, we support both the offshore and onshore wind turbine industries, throughout the lifetime of power generation equipment. Our products are in daily use during the manufacture of the turbine components, the loading and unloading vessels with our Harbour Cranes and materials handling applications on wind turbines.”
Gwynt y Môr offshore wind farm is being constructed 13 km off the north Wales coast, in water depths of 12 to 28 m. The development will comprise 160 wind turbines and two substations, making it one of the largest European wind farms currently under construction. Turbine foundation installation is scheduled for the fourth quarter of 2011, with the first power generation likely to take place during 2013. It is anticipated that the wind farm will be fully operational towards the end of 2014, generating 576 MW, which is equivalent to the average annual power supply for approximately 400,000 homes.
