DNV GL has been contracted by Transmission System Operator TenneT to deliver complete project certification for two offshore substations (OSS) for the Hollandse Kust Zuid offshore wind farms in the Dutch North Sea.
TenneT is to deliver five offshore substations to guarantee power transmission to the shore. Each substation will have a capacity of 700 MW, and will be connected to two wind farms in the Dutch North Sea. DNV GL recently issued a Statement of Conformity allowing the jacket installation of the Borssele Alpha OSS, and expects to issue the full project certificate in 2019. Project certificates are expected to be issued in 2020 for Borssele Beta, 2021 for Hollandse Kust Zuid Alpha and 2022 for Hollandse Kust Zuid Beta (subject to the project receiving final approval). Following a tender process, TenneT awarded the contract to certify the Hollandse Kust Zuid Alpha and Beta OSS projects to DNV GL. This follows a previous agreement for DNV GL to certify the first two OSS platforms – Borssele Alpha and Beta – which are currently under construction. The certification will be carried out according to DNV GL guidelines DNVGL-SE-0073 & DNVGL-ST-0145.
