May 21 (Renewables Now) - Wind industry supplier Sif Holding NV (AMS:SIFG) said Monday it will make two monopiles for the 19-MW Borssele V offshore wind project located at a designated innovation site in Dutch waters.
The project will feature several novelties such as the use of slip joint technology on one of the monopiles to connect it to the transition piece. One foundation will be equipped with conical-shaped end pieces of the monopile and the transition piece. This connection, which Sif described as stacking coffee cups in a cupboard, will help save installation time offshore.
The surface of the other monopile will be aluminium sprayed to avoid corrosion and minimise the maintenance, Sif said.
MHI Vestas Offshore Wind has been selected to supply two 9.5-MW turbines for the wind farm. Their grid connection is slated for 2021.
The site V in the Borssele wind farm zone was awarded in a tender to Two Towers BV, a consortium formed by Van Oord NV, Investri Offshore BV and Green Giraffe BV, in 2018. The small area is located more than 20 km off the coast of Zeeland within the Borssele site III.
According to the Netherlands Enterprise Agency, the area has been designated as an “innovation site” to provide Dutch companies with opportunities to develop and test novel offshore wind energy solutions, increase their market and export potential and contribute to the local economy.
