Three export cables successfully installed
Jan De Nul Group’s Cable Laying Vessel Willem de Vlamingh has successfully installed the three export cables on the 120MW Formosa 1 Phase 2 wind farm in Taiwan.
As part of Jan De Nul Group’s EPCI contract for building of the overall Balance of Plant, Jan De Nul Group mobilised its Cable Laying Vessel Willem de Vlamingh to install the 17 inter array and 3 export cables.
These three export cables have been successfully installed within one week. Thanks to its shallow draft design, the Willem de Vlamingh was able to position in water depths of not more than 7 metres, thus limiting the shore pull distance to around 1,750 metres. At the beach landing, the cables have been pulled through three HDD ducts into the transition joint bays. The Willem de Vlamingh is also acting as Trenching Support Vessel for the jet-trenching of both the export as well as the inter array cables.
For the installation of the export cables, Jan De Nul Group relied on its local supply chain network for the performance of the beach pull assistance works including installation of the HDD ducts, dive support and supply and operation of the support vessels.
About the Formosa 1 Phase 2 OWF
The wind farm is owned by Formosa I Wind Power Co. Ltd., a partnership of Orsted (35%), JERA (32.5%), Macquarie Capital (25%) and Swancor Holding (7.5%).
The offshore wind farm is located around six kilometres off the west coast of the Miaoli district in the Taiwan Strait, with water depths ranging between 15 and 30 metres. The original demonstrator project, comprising two wind turbines with a total capacity of 8MW, is currently being extended. This second phase will add 20 offshore wind turbines with a total capacity of 120MW to Formosa 1's current 8MW capacity. Formosa 1 will be the first commercial-scale offshore wind farm in Taiwan before 2020.
