DONG Energy - Half of 111 is 55½

In March 2013, the installation vessel, Sea Jack, had lifted the tower and the nacelle in position on turbine F26, which is positioned at the northern end of Anholt Offshore Wind Farm. 55½ wind turbines have now been erected at the wind farm, and the task of erecting the grand total of 111 wind turbines is now exactly halfway.

Sea Jack just managed to complete the operation before leaving the area to deal with other tasks, but turbine installation activities continue at full speed. The three installation vessels; Sea Installer, Sea Power and Sea Worker will continue work at the site and will be exploiting suitable weather windows to install wind turbines. In April, Sea Installer will be needed elsewhere, and the remaining two installation vessels will then complete the installation work.

DONG Energy expects the erection of all 111 wind turbines to be completed and the wind turbines to be operational by summer, as planned.

"We've reached a significant milestone with the installation of these wind turbines. Despite the installations having been carried out during the winter period, we've succeeded in maintaining satisfactory progress in the realisation of Anholt Offshore Wind Farm, and in February alone, 20 wind turbines have been installed," says Flemming Thomsen, DONG Energy’s Project Director.

The weather sets the pace:
Turbine installations are dependent on weather conditions, and the harsh weather seen this winter has meant that, for several periods, it has not been possible to install wind turbines.

Wind and waves have reduced installation speed due to technical limitations of the installation vessels, but all weather windows enabling installation have been used optimally.

Wind turbine installation activities commenced on 1 September 2012 and the first wind turbine was erected on 3 September. It was this very wind turbine that produced the first power generated by Anholt Offshore Wind Farm at 11.00 on Friday 21 September.

On 6 March at 14.43, 55½ wind turbines had been erected, and of these 48 wind turbines had been energised and 33 had produced power.

Facts:

• DONG Energy has worked to realise the extensive construction project since being awarded the concession in 2010.
• On New Year's Eve 2011, at 19.00 hours: the rest of Denmark was gathered for their celebrations. Meanwhile, the installation vessel, Svanen, hammered a foundation pile into the seabed and commenced construction activities in the Kattegat. By 27 July 2012, all foundations were in place.
• In June 2012, cable-laying vessels commenced work laying the connecting cables on the seabed between the substation and the 111 foundations. By 12 September – three weeks ahead of schedule, all cables were in place.
• On 5 December, technicians reported that all cables were ready and, shortly afterwards, on 13 December 2012, all 111 installations were energised and connected to the Danish electricity grid.
• Wind turbine installation activities commenced on 1 September 2012, and the first turbine was erected on 3 September.
• Anholt Offshore Wind Farm will have a total capacity of 400MW, which means that it will be Denmark’s largest offshore wind farm.
• The wind farm is being erected by DONG Energy, which owns 50 per cent. The remaining 50 per cent is co-owned by PensionDanmark (30 per cent) and PKA (20 per cent).
• The overall production for 2012 was 31.5GWh corresponding to the annual electricity consumption of 7,875 households. This was possible even though the first wind turbine in the array only started production on 21 September 2012.
