Jan De Nul has completed installation of all twenty foundations on the 120MW Formosa 1 Phase 2 wind farm in Taiwan.
As part of Jan De Nul’s EPCI contract for building of the overall Balance of Plant, Jan De Nul mobilised the Seaway Yudin to install the 20 foundations.
The foundations consist of a monopile and transition piece structure with a grouted connection. The monopiles range from 752 to 1230 Ton with a maximum diameter of 8.4 meter and a length ranging from 60.1 to 79.5 meter. Each of the transition pieces weigh 465 Ton and consists of five internal platforms, an external platform and boat landing.
Over a period of less than one year Jan De Nul managed to complete the fabrication process, the sea transport, the load in and out at the marshalling harbour in the Port of Taichung, and the installation of all foundations offshore.
With the parallel installation of scour protection, export and inter array cables being well underway, Jan De Nul is fast-tracking the completion of the project.
The offshore wind farm is located around 6 kilometres off the west coast of the Miaoli district in the Taiwan Strait, with water depths ranging between 15 and 30 metres.
