The Boskalis/Volker Wessels joint venture needed to transport and install 67 monopile foundations on the Veja Mate offshore wind farm using Seajacks’ jack-up vessel Scylla. TWD designed seafastening cradles as well as a custom lifting beam and rigging arrangement to safely lift the monopiles.
Since the monopiles had a diameter of 7,8 meters and weighed up to 1300 tonnes, we had to tackle the challenge of fitting all the monopiles on the deck. Therefore, our teams designed the seafastening cradles in a way that maximized the deck space and distributed the transit loads effectively. In addition, TWD managed the fabrication process, which included the follow-up of technical queries, checking the fabrication and test procedures, performing site inspections as well as providing consultancy during the dimensional control, FAT and SAT tests.
