JAN DE NUL COMPLETES INSTALLATION OF FORMOSA 1 PHASE II FOUNDATIONS
As part of Jan De Nul Group’s EPCI contract for building of the overall Balance of Plant, Jan De Nul Group 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 Group managed to complete the fabrication process, the sea transport, the load in and out at the marshalling harbour in the Port of Taichung, and finally the installation of all foundations offshore. With the parallel installation of scour protection, export and inter array cables being well underway, Jan De Nul Group are fast tracking the completion of the project.
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 6 kilometres off the west coast of the Miaoli district in the Taiwan Strait, with water depths ranging between 15 and 30 metres. The project comprises 2 phases: phase 1 of two wind turbines with a total capacity of 8MW. Extended from phase 1, 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.
