First Monopile Loaded at Sif’s Maasvlakte 2 Location

Sif loaded its first monopile on board a seagoing vessel. The ship in question is the Innovation, a heavy-lift jack-up vessel owned by Geosea, part of the Belgian DEME Group. It was also the first job handled at the new section of Maasvlakte 2’s deep-sea quay (port number 8317). Monopiles are used for the foundations of offshore wind turbines. They can weigh up to 1,000 metric tons apiece. All in all, four monopiles will be loaded for transport today. Together with the so-called ‘transition pieces’: connecting sections that are used to join the turbine towers to the monopiles.
