The second offshore transformer station topside for the Hollandse Kust Zuid (HKZ) grid connection has departed Drydocks World Dubai’s fabrication yard and is on its way to the Netherlands for installation.


The topsides – Alpha and Beta – will connect the offshore wind farm with the Dutch mainland at the Maasvlakte. The 700 MW Beta topside weighs 3,950 tonnes and was loaded onboard Boskalis’ heavy transport vessel Mighty Servant 3. 

Mammoet was commissioned to perform the weighing, transport and load out. The Dutch heavy transport specialist also supported the load-out of the Alpha topside, which departed the UAE during November 2021. It has since been installed at the wind farm site by Allseas’ installation and decommissioning vessel Pioneering Spirit.
