Jan De Nul Group successfully completed the installation of the 4 export and 47 inter array cables on the Formosa 2 Offshore Wind Farm in Taiwan.

With the achievement of these major milestones, Jan De Nul brings its EPCI scope onto the final straight towards completion in the coming weeks.

During the installation activities, Jan De Nul also managed the underwater noise monitoring and marine mammal observation in compliance with the environmental restrictions and permits.

In 2020, Jan De Nul subcontracted the manufacturing of 34.5 km of export cables and 87 km of inter-array cables to LS Cable. Jan De Nul’s shallow water Cable-Laying Vessel Willem de Vlamingh and Multipurpose Vessel Connector picked up, transported and installed the cables in 2021 and 2022 respectively. Both vessels also acted as trenching support vessel to bury the cables with a jet trencher in certain sections of the cable routes. Jan De Nul’s Trailing Suction Hopper Dredger Niña and Francis Beaufort performed pre-trenching in the harder sections.

The four export cables were pulled through the drilled HDD pipes nearshore in 2021, and were finally joined onshore with the land cables at the transition joint bays. Installation of the 47 inter-array cables commenced in May 2022 and was completed on 1 September.

In the coming weeks, Offshore Support Vessel Orient Constructor of local partner DFO will continue facilitating walk-to-work access for the teams finalising the terminations of the cables, allowing the energization of the entire wind farm.

Offshore Support Vessel Grand Canyon 2 and Jan De Nul’s Connector will complete the remaining cable burials and stabilizations in the course of September.
