The wind turbines were transported along purpose-built gravel roads.
The addition of these 54 wind turbines, supplementing the existing 152 wind turbines at Clyde Wind Farm, makes the Scottish wind farm, covering 47 square kilometres, one of the biggest in Europe. And, as in 2009 when the farm was constructed, DSV Projects is again responsible for delivering the 54
Siemens wind turbines. DSV had overarching project responsibility and managed the shipment of blades, nacelles and hubs from the Danish cities of Aarhus and Aalborg to Glasgow. The towers, however, were picked up from a factory in nearby Campeltown and shipped to the King George V Docks in Glasgow. The last leg of the transport from Glasgow to the Clyde Wind Farm was by road through hilly terrain roughly 100 km south-east of Glasgow.
Concurrent with the Clyde Wind Farm order, DSV was commissioned to deliver a total of 147 wind turbines to six other wind-turbine projects in Scotland.
The remote location of the Clyde Extension posed many challenges. More than 105 km of gravel roads were built in 2009 to access the remotest corners of the wind farm, which, when fully ready for commissioning later this summer, will generate a total of 528 MW (172 MW from the added turbines alone).
Thirteen ships from Denmark and seven from Scotland were used to transport the turbines. Six hundred loads were conveyed from the Glasgow waterfront to the wind farm itself, many of which were oversize with a total weight of up to 150 tonnes.
The Glasgow waterfront was a big challenge as many projects were coming in via Glasgow during this same period. This required large-scale coordination to ensure that the components could be placed in the storage area – and this coordination was done in close collaboration with Peel Ports, the overall port operator.
"We were delivering parts and components from late June 2016 to April 2017, and because of the area’s hilly landscape, shortage of public roads and large amount of rainfall and snowfall during the period, it was a very challenging process," explain Henrik Vammen and Mads Lunde, Project Managers, DSV Projects.
Clyde Wind Farm is not situated along a public road, so conveying the 600 loads – with a total weight of almost 150 tonnes – through the hilly area was far from problem-free.
"Safe and successful" transport
Both heap praise on their partner, Mammoet Wind, which was contracted by DSV to handle
transport from the waterfront to the site and for the professional management of road transports in Scotland. But the project would not have been successful were it not for the efforts of the customer, Siemens, to thoroughly familiarise itself with the challenges that actually emerged.
Countless factors affect a project of this size, but Siemens fielded a team who took a very solution-oriented and proactive approach to the task,
Henrik Vammen says. He and his DSV colleagues were highly commended by the customer, who urged a meeting of everyone involved to summarise which factors had been crucial for the "safe and successful" transport of the wind turbines.
"The Siemens organisation does not say such kind things very often, so we’re very proud of this. And we’re keenly aware that the praise also goes to our colleagues seconded to Glasgow for a long period of time, not to mention our very adept partner Mammoet Wind and the dockworkers involved in the project. It was a team effort involving many different partners," he says.
