RWE Innogy charters mobile accommodation platform
for Nordsee Ost Offshore
Wind Farm construction site
April 30, 2014 + + + RWE Innogy has awarded Dutch
company Jack-Up Barge B.V. the contract to provide an accommodation
platform at the construction site of the Nordsee Ost Offshore Wind Farm.
The jack-up vessel “JB 114” will temporarily accommodate up to 40
employees to carry out commissioning works at the wind farm’s internal
transformer station from mid-July.
“With this platform we are
providing a comfortable home for our employees during the transformer
station’s commissioning phase of about two months and safe access to their
place of work. The jack-up legs will lift the platform out of the water
right beside our substation. As a result, the vessel will be in an
elevated position and therefore won’t be exposed to the waves.
A
gangway connecting the accommodation unit with our substation will be
placed almost 25 meters above the water surface”, explains Marcel Sunier,
Project Director for the Nordsee Ost wind farm at RWE Innogy.
Maarten Hardon, Commercial Director of Jack-Up Barge B.V., adds: “Jack-Up
Barge is proud to be awarded a second contract by RWE within a year. After
the successful completion of the Gwynt y Môr project, Jack-Up Barge is
once again looking forward to working with one of the leading companies in
the offshore wind sector. This contract reaffirms the proven capabilities
of the JB 114 in the offshore wind industry.”
The platform provides
bedrooms for up to 40 persons as well as conference and office rooms.
Moreover, the vessel has a deck of approximately 1,000 square meters, and
a main crane with a lifting capacity of 300 tonnes. The existing
helicopter landing platform allows flexible crew turnover. This is
essential because up to 40 technical staff will stay offshore for the
total period of the commissioning works.
“We are happy to secure a
contract with a reliable partner who has already done a good job for our
sister project Gwynt y Môr off the coast of North Wales,” says Alexander
Ohff, Project Manager responsible for the marine operations at RWE Innogy.
The internal transformer station is the nerve centre of the wind
farm. It transforms the electricity generated by the wind power systems at
33 kilovolt, to a transmission voltage of 155 kilovolt so that it can be
transmitted by submarine high-voltage cable to the coast. The transformer
station of the Nordsee Ost wind farm is about 15 meters high and weighs
around 2,000 tonnes. Like the wind turbines, it is anchored to the seabed
on a steel jacket foundation and stands some 35 meters above sea level
once fully assembled.
The 700 tonnes steel foundation for the
transformer station was installed in July 2013. Welding work is initially
carried out during the commissioning phase to connect the transformer
platform (topside) with the foundation, which is referred to as “wedding”.
The overall system is then electrically put into service and the wind
farm’s internal cabling as well as the external cables of the grid
operator (Tennet) are connected.
The installation of all 48
foundations for the Nordsee Ost wind turbines were completed in mid-March
2014. The erection of the wind turbines is due to start in May 2014. Once
the wind farm is completed, estimated to be in Spring 2015, Nordsee Ost
Offshore Wind Farm will have an installed capacity of some 295 megawatts
(MW) and be capable of producing enough electricity to supply the
equivalent of some 300,000 residential households per year. Equipped with
the most powerful, modern offshore turbines, Nordsee Ost ranks among the
largest commercial wind power projects off the German coast
