construction for the Borssele
V offshore wind
farm is expected to start next month. The project was awarded to the Two
Towers consortium (Van Oord, Investri Offshore and Green Giraffe) in April
2018 as an innovation site.
Located 20 km off the Dutch coast, the site will feature two V164-9.5
on monopile foundations manufactured by Sif. Installation of the monopiles
is due to get underway in April. Van Oord's construction vessel Aeolus
is due on site after completing foundation installation at the Borssele
farm, currently under construction.
Borssele V will share a grid connection with Borssele
the Borssele Beta offshore platform. The 3,700 tonne topside is scheduled
for sail away mid-March and will be operational later this year.
Two Towers intends to implement an innovative 'split joint' clamping connection
solution between the foundation and tower. This technology, developed in
collaboration with Van Oord, offers an alternative to flanged or grouted
connections and is expected to be maintenance-free, and reduce installation
time. The consortium will also use innovative aluminium-based protection
coating (TSA), which ensures a higher life expectancy of the mast and requires
less maintenance will be tested. Impressed Current Cathodic Protection
(ICCP) monitoring system and an oval cable hole will also be deployed at
Furthermore, new eco-designs for scour protection will be tested to determine
effects on the maritime environment. This includes the use of scour protection
in creating reef systems, such as oyster reefs, which are designed to help
promote a healthy and diverse marine ecosystem.
The Dutch government aims to increase the installed offshore wind capacity
to 4.5 GW by 2023 across the Borssele,
wind energy areas. The tender for the latter is due to open for bids in
April 2020. A further 7 GW of new projects are scheduled to enter construction
during the latter half of the decade, with least 11.5 GW expected to be
operational by 2030.
