This
morning around 09:30 hours at sea the OHVS
(Offshore High Voltage Station) was
lifted onto its final resting place at the Eneco
Luchterduinen offshore wind farm,
The specifications of the OHVS
are awesome requiring the
RAMBIZ
to lift a structure that :-
- Weighs as much as four Boeing 747's
(around 900 tonnes)
- Is equivalent of a modern 4 floor office
building
- Is 24 meters long, 23 meters wide and
16 meters high.
- Is full of transformers and switchgear.
- Is full of computers for security and
control; includes emergency and air conditioning systems.
- In case of emergency or the need to
stay on the
OHVS there is room for maintenance
staff to sleep and is stocked with emergency rations.
The
transformer station collects
the electricity generated by the 43 wind turbine transforming the delivered
33kV to 150kV, and then acts as the starting point of 25 kilometer power
cables to the landfall on the coast at Noordwijk. From here an 8km underground
cable will transport the electricity to the onshore substation at Sassenheim.
All foundations and cable connections for the wind farm were completed
in 2014.
Van Oord acted as the main contractor
for Eneco
Luchterduinen offshore wind farm.
Van Oord was responsible for the the design, construction and installation
of the OHVS with the FICG consortium (a collaboration between Cofely Fabricom,
Iemants and CG). The overall design, design and assembly was executed by
Cofely Fabricom in Hoboken (near Antwerp). Iemants from Arendonk, Belgium
were responsible for the design and manufacture of the steel work for the
platform. CG did the design, supply and installation of high voltage components.
The construction of Eneco
Luchterduinen offshore wind farm
is now in full swing. The foundations
for the Substation
were installed back in September
by Van Oord, the one of a kind foundations in which the monopile and the
transition piece were built as one were installed by the vessel Aeolus.
From April this year 43 Vestas wind
turbines will be installed by Van Oord and at the end of 2015, Eneco
Luchterduinen offshore wind farm
should be operational and generating green electricity for nearly 150,000
households. The wind farm is a joint project of Japan's Mitsubishi Corporation
and Eneco Group.
For the spectacular operation the heavy
lift vessel the Rambiz and the Belgian Scaldis were deployed. This floating
crane (Rambiz) raised its
lifting arms of 80 meters to lift OHVS
station yesterday in IJmuiden.
The wind farm is a joint project of Japan's
Mitsubishi Corporation and Eneco Group.
