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.
