Commissioning
in progress The
commissioning of the 80 wind turbines in the wind farm is in progress.
At present (November 5, 2002) 30 wind turbines have been commissioned
and 13 are under start-up. The commissioning is 3-4 weeks behind
schedule. Vestas
has increased the number of commissioning teams and transport boats,
and the two previous crane vessels permanently function as floating
hotels in the wind farm area. Furthermore, nightwork is performed
under tight rules. These
initiatives mean that all the wind turbines will be commissioned by
Christmas 2002.

Damage
to the 2 MW offshore wind turbine in Tjæreborg At
approx. 9.00 a.m. on Monday November 4 the new 2 MW offshore wind
turbine in Tjæreborg was damaged. The wind turbine is a prototype of
the 80 wind turbines, which Elsam has erected at Horns Rev. Eye
witnesses recount that the wind turbine exceeded the maximum allowable
numbers of rotation whereupon the blades collapsed. The wind speed at
that time did not exceed 10 m/s. The wind turbine has not yet been
finally taken over by Elsam. Already on Monday engineers from Vestas
started investigating the reason for the damage and to find out
whether the fault can also occur on the Horns Rev wind turbines.

Helicopter
transport Elsam
has entered into an agreement with Uni-Fly A/S on helicopter transport
to the offshore wind turbines at Horns Rev. Uni-Fly A/S is to
transport service engineers to the wind farm in connection with
service and inspection. The
helicopter to be used for this transport, has just arrived at Esbjerg
Airport, where Uni-fly marked the occasion with an open house
arrangement. The helicopter is to transport service engineers to the wind turbines where they are hoisted down onto the platform placed on the wind turbine roof. Subsequently, the service engineers are hoisted from the platform like when rescue helicopters pick up people in distress. This method is widely used abroad, where, among other things in the channel area, shipping pilots are moved from vessel to vessel by helihoist.

New
offshore foundation type used in Frederikshavn On
Wednesday October 30 the new patent pending foundation type “bucket
foundation” was used for the first time in full scale. The
foundation is to carry Denmark’s largest wind turbine so far, which
is one of the four 125 m high offshore wind turbines to be erected off
the harbour of Frederikshavn. The
company MBD Offshore Power A/S – a development company with Novasion
aps, Ørskov Staalskibsværft A/S, Bladt Industries A/S, MarCon A/S
and Elsam A/S as shareholders – has been in charge of the commercial
development of MarCon’s patent. The foundation has been developed in
a close and formalized co-operation with Aalborg University Centre. The
wind turbine to be placed on the new foundation type is Denmark’s
largest – a 3 MW Vestas wind turbine. The wind turbine is expected
to be placed on the foundation in week 49 and is to be in operation by
the end of 2002. For time reasons the remaining three wind turbines
are placed on traditional foundations and are expected to be put into
operation by June 2003. |

Clean-up
on site As
part of the clean-up after the on-site works at Horns Rev, the
compression chamber was removed from the transformer platform. The
compression chamber was placed on the platform as a safety measure in
connection with the numerous diving operations performed in connection
with the construction of the offshore wind farm.
